Microchip PIC Arduino based programmer

I love to program programmers. Yo dawg...

Similar projects worth following
This is more software than hardware project running on vanilla Arduino, but for sake of completeness I'm going to build simple dedicated hardware instead.
More to come.

For #Micro progmeter project I want to deliver full set of open-source materials, but it would be shame if folks trying to replicate the project would have to buy another programmer to flash the PIC MCU, so I decided to do a little bit of brain stretching and implement PIC16F1xxx programmer with... Arduino, just because it is low cost and available platform.

Together with SDCC compiler this serves as completely open-source basis for PIC16F1xxx and similar projects.

The current project status: Programmer working, sources need cleanup.

  • version 0.99

    jaromir.sukuba06/28/2018 at 11:17 1 comment

    Support for new PIC18FxxQ10 is added (by the way, its FLASH is programmed in different way than most of the other new PIC16 and PIC18 devices, thank you Microchip for another programming algorithm to implement), now it's 439 devices in total. It looks like there are no other LVP programmable 8-bit PIC devices, so probably I can polish it and release version 1.00 soon.

  • version 0.98

    jaromir.sukuba06/19/2018 at 13:13 0 comments

    As usual, on github.

    I added some new devices - PIC16F184xx, PIC18FxxK40 and PIC18FxxK42, support list having 433 entries by now.

    Also, programming speed for some devices is increased.

  • version 0.97

    jaromir.sukuba06/18/2018 at 11:59 1 comment

    60 new devices from PIC16F153xx, PIC16F183xx, PIC16F188xx and PIC16F19xxx added, resulting in support for 379 devices in total. For a moment, I'm adding support for new MCUs faster than Microchip can develop them, neat!

    I tested 5 new ones, resulting in 52 MCU types tested.

  • version 0.96

    jaromir.sukuba06/17/2018 at 23:11 0 comments

    After nearly two years, I refreshed this project again.

    Apparently, Microchip introduced new programming specification for newer PIC devices, like PIC16F1xxxx and PIC18FxxK20 and PIC18FxxK22. The old format was LSB first, either with mix of 8/14 bit long words (for PIC16Fxxx) or 8-bit long words, but a lot of direct instructions entering (PIC18). This seems to be unified now (see the famous XKCD comics) with MSB-first and 8-bits only words. Nice initiative, only if there were already a few different formats among PIC devices.

    Honestly, I was too lazy to implement it, but there is already quite a few "new format" devices in the wild, so I finally got myself to add it to pp3 programmer, so here you go. Only PIC16F188xx are added, but more will follow.

  • pics of PICs, version 0.95

    jaromir.sukuba09/16/2016 at 11:15 1 comment

    Today I made some more progress. I added support for more PIC18FxxKxx devices, so the total supported devices count is 305. There will not be much more of them.

    I tested a few new ones, including PICs in TQFP package. Unlike for DIP packages, breadboard and wires are not enough, so I had to use TQFP adapter I made few years ago for PIC24 and PIC32 series, but with single cut trace it works for PIC18 too.

    There is nothing more than micro and decoupling caps. By the way - JS09 really means year 2009. The time flies.

    For this adapter I made simple testbench of perforated PCB.

    With this one I tested PIC18F66J15, 67K22 and 67J50, each on its own breakout.

    And this is gallery of all PIC devcies I programmed with this Arduino programmer. Every single MCU here has blink a LED program flashed. Much blinking power, very wow.

  • version 0.94 - PIC18FxxKxx CAN devices added

    jaromir.sukuba09/14/2016 at 16:42 0 comments

    In version 0.94 I added support for CAN devices like PIC18F25K80, 12 new in total. New firmware is released too.

    Everything is on github.

  • version 0.93

    jaromir.sukuba09/12/2016 at 09:28 0 comments

    I hunted a bug with programming PIC18F24J10, but finally I got it working - so version 0.93 is out.

    I ordered some more PIC18FxxJxx devices to test the programming protocol implementation. After tested, I'm going to do the final sources cleanup and release version 1.00.

    Files are on github, as usual.

  • Version 0.92 - major rework

    jaromir.sukuba09/09/2016 at 11:14 0 comments

    I reworked the MCU selection code. The if-then structure was OK for dozen of devices, but with more than 200 supported MCUs, it became messy. So I rewrote it into simple plain text file database with entries like

    # PP3 device database for version 0.92
    # 
    # name   flash page  ID  mask family_type
    # flash size and page size in bytes 1 WORD = 2 BYTES
    # 
    # PIC16 family
    16f1503   4096   32 2CE0 FFE0 CF_P16F_A
    16lf1503  4096   32 2DA0 FFE0 CF_P16F_A
    16f1507   4096   32 2D00 FFE0 CF_P16F_A
    16f1508   8192   32 2D20 FFE0 CF_P16F_A
    16f1509   16384  32 2D40 FFE0 CF_P16F_A
    16lf1507  4096   32 2DC0 FFE0 CF_P16F_A
    16lf1508  8192   32 2DE0 FFE0 CF_P16F_A
    16lf1509  16384  32 2E00 FFE0 CF_P16F_A
    16f1454   16384  64 3020 FFFF CF_P16F_A
    16f1455   16384  64 3021 FFFF CF_P16F_A
    ...
    ...
    so it is easy to edit (add new PIC devices or fix mistakes in existing) by hand without recompiling the code. The pp3 takes all the information about device to be programmed from here. The original source shrunk from 2700 to 900 lines of code.

    I also added 67 more PIC18FxxJxx devices and one PIC16F, so it supports 273 devices in total. At last, I tested support for another 7 devices, all of them working on a first try. I feel like time for 1.0 release is near.

    Everything is on github, as usual.

  • After 0.9 comes 0.91, obviously

    jaromir.sukuba09/06/2016 at 12:16 5 comments

    I decided to release version 0.91 - the previous should be 0.90, then.

    No matter what, I added some more devices - 205 devices supported in total.

    I also changed somehow serial port handling, resulting in higher programming speed, especially under windows. PIC16 programming algorithm got a bit more intelligence, resulting in faster programming.

    Before 1.00 release I'd like to rework the MCU type selection into table driven function instead of huge if-then-else behemoth and set support for all LVP ICSP-able 8-bit PIC devices.

    Everything is at github, as usual https://github.com/jaromir-sukuba/a-p-prog

  • Version 0.9 - 175 devices supported

    jaromir.sukuba09/05/2016 at 20:55 0 comments

    Oh here we go, version 0.9 - this means first "normal" release 1.0 is close.

    I added a lot of new devices, some new are tested. I fixed some bugs around serial port and hex file handling. The PIC name is now case non-sensitive. 175 devices is in support list in total.

    Everything is on github, as usual.

first of all, I want to greatly thank you for sharing this project with us.

I'm using Arduino Mega 2560 to program a pic 18f5k50 but I'm getting an error that I have not been able to solve. I would appreciate help :D

I took  a look into the arduino code in order to make myself with some clues but I had no success, there was no much that I could understand.

This is the output of the terminal after running pp3 ( I placed the hex file in the sw folder )

juan@juan-pc:~/Desktop/a-p-prog-master/sw$ sudo ./pp3 -c /dev/ttyACM0 -t18f45k50 -s 1700  Mne.X.production.hex

Wrong device ID: 0000, expected: 5c00
Check for connection to target MCU, exiting now
juan@juan-pc:~/Desktop/a-p-prog-master/sw$ 

I'm guessing that somehow the pp3 script is having issues to get device id from the device.dat file, but thats just a hunch, I have no technical reason to say that.

EDIT: 

When running the same commad as above as root user, the terminal output log changes a bit, here it is:

Hi, I've successfully used your programmer on linux (with a common Arduino UNO) to flash a PIC18F47Q10!

Please note that the Device Id of PIC18F27Q10 and PIC18F47Q10 are exchanged, so I've corrected at first them in your "pp3_devices.dat" files.

I've also noticed that  the MCLR/VPP pin (A3) is normally at HIGH level. This can be an issue when connecting your programmer to self-powerd boards. I've checked on both the MPLAB Pickit 4 and MPLAB SNAP programmers and they leave the MCLR/VPP pin at GND or 3-stated.

So I've modified your .ino and added a small switch on A2 so I can put your programmer into a "stand-by" state with all the ICSP pin at GND (or 3-stated) . This allows to connect safely the ICSP cable with an un-powered target board while the Arduino Uno is powered. Then I can power the target board and change the position of the switch to let  the programmer operate as intended.

After the programming I do in sequence: set the switch to "stand-by" again, reset the Arduino UNO, un-power the target board, disconnect the ICSP cable, and finally un-power the Arduino UNO.

Here the changed part at the beginning of your "int main" function:

.....

int main (void)
{

  pinMode(13, OUTPUT);
  pinMode(A2, INPUT_PULLUP);
  while (digitalRead(A2))
  {
    digitalWrite(13, HIGH);
    _delay_ms(200);
    digitalWrite(13, LOW);
    _delay_ms(200);
  }

.....

The blinking Led of the Arduino UNO is used to give the feedback that the programmer is in the "stand-by" state, and the connection or disconnection to/from the target board is safe.

Thanks for this beautiful programmer!

I'll use it to give a simple and cheap way to program the PIC18F47Q10 MCU used inside my 68k-MBC board.

Here a couple of images of my Arduino Uno and the "ICSP Shield":

Hello,

I took a look at programming specs of Q43 and unless I overlooked some nasty detail, it should have the same programming protocol as some other newer PIC 8-bitters, so I think Q43 (and other Qxx for that matter) should be relatively easy to add.
I have some other TODO work at this project, so as soon as I get the Qxx parts in my hands I'll try to add support to those and release new version.

I found my problem. I skipped the part that says that you have to inject some code in your arduino to allow it to work as a programmer. I was digging on the project resources, found the .ino file under https://github.com/embhobbb/a-p-prog/blob/master/fw/pp/pp.ino and uploaded it to my Arduino successfully.

Now the problem I have is that when I run pp3.exe on port COM9 (my arduino port) I'm getting:

Thank you.

For Atmega168, AFAIK there are no modifications needed other than recompiling the project for given AVR.

PIC16F876A is not supported and will not be supported, as this is low-voltage (LV) programmer and can't do high-voltage programming without major hardware modifications. This particular PIC is older one, not supporting LV programming

  Are you sure? yes | no

mechtatelnyi1 wrote 12/25/2018 at 13:48 point

2.4.1 LOW VOLTAGE ICSP
PROGRAMMING MODE

Low Voltage ICSP Programming mode allows a
PIC16F87XA device to be programmed using VDD
only. However, when this mode is enabled by a configuration
bit (LVP), the PIC16F87XA device dedicates
RB3 to control entry/exit into Programming mode.
When LVP bit is set to ‘1’, the low voltage ICSP programming
entry is enabled. Since the LVP configuration
bit allows low voltage ICSP programming entry in
its erased state, an erased device will have the LVP bit
enabled at the factory. While LVP is ‘1’, RB3 is dedicated
to low voltage ICSP programming. Bring RB3
and then, MCLR to VDD to enter Programming mode.
All other specifications for high voltage ICSP apply......from datasheet, it does have support of LVP

  Are you sure? yes | no

jaromir.sukuba wrote 12/25/2018 at 14:12 point

@mechtatelnyi1  thanks for datasheet quote. I understood it as question regarding LVP on those parts - this mode requires manipulating PGM pin, either manually or from arduino. Apart from being cumbersome, it results in losing one IO pin; there are much newer parts supported by this programmer, being cheaper, more packed with peripherals and still being pin compatible. Thus, I'm not planning to add support for 16F877 and similar.

  Are you sure? yes | no

  Are you sure? yes | no

jaromir.sukuba wrote 12/26/2015 at 14:18 point

Yes, dsPIC33F are technically possible. 

Speaking from memory, all 16- and 32-bit MCUs from Microchip are using low voltage on MCLR and serial key on PGC/PGD pair to enter programming mode (as well as newer 8-bits, like PIC16F1xx, like PIC18F1829 and some PIC18, for example PIC18F46K22 and similar).

On the other hand, there are dsPIC33 with 512kB of FLASH. Programming such as amount of data with this simple and really slow programmer would be pain in the ass. Bottleneck of data throughput here is simple polled firmware architecture and slow serial transfer - acceptable only for few kB of data for 8-bitters.

But it is good to know there is demand for other than PIC16F1xxx devices. I'll start thinking about how to improve the programming speed and scan through programming specs of PIC devcies to determine what types are possible to implement.
