While whizzing through the code trying to scrounge verified keyboard scan codes and flags, I found some some buried treasure in the form of an undocumented test routine. It's not that exciting -- it just fills the current file with some sample...
Sometimes, I get burned out by the hardware aspect of the project. When this happens, I often wonder to myself, "Man, if only I had the Kestrel *finished*, then I can work on the software." I reached that point not too long ago.So, I worked...
Now it's time to build something cool ;)Unfortunately I don't have schematics for this one - I drew PCB as is (using pcb from GEDA) based on original nedoPC-85-A schematics with some thoughts from my mind regarding MK85 cloning - so the thing is...
today my chaos-driven round robin scheduler gave some processing time to this project - yay!Printed, laminated and cut out with standard office tools:..."assembled":First I tought about drawing the outer ring (time + business hours / rude to call ring)...
I've got the BIOS loading for Multi-boot Multicomp. It boots up to the Multi-boot prompt. > Available Commands: :ccxxxxiibbbbbb Load Intel-Hex file record Rxxxx Run from address xxxx Sddd System boot Iddd Init: Format directory Pddd[,xxxx] PutSys: write...
Paul suggested an alternate solution, namely to turn off LEDs by setting them to high impedance instead of 0V. That way the tiny LED capacitances have no way to charge and thus no ghosting. I tried it and it works! Awesome "zero extra components" solution,...
So since the Teensy++ 2.0 bootloader is not available and I'm not feeling comfortable to learn all the bells and whistles of USB communications I was looking for other options. Googling "at90usb1287 arduino" I found this https://github.com/mattairtech/ArduinoCore-avr...
To implement the ESP-NOW Protocol, we first need to understand how it works in details. The datasheet doesn't say much on the really low level, especially on the acknowledgment behavior. To understand what ESP-NOW does, I use Wireshark with my PC Wifi...
In preparation for the next logs I wanted to talk a bit about the pin compatibility between the Pro Trinket and the Pro Micro. The reason why I also want to integrate the Pro Micro is that it's more commonly available and cheaper.---------- more ----------The...
If you head on over to the SBC-85 project website, the documentation and build files for the cassette tape interface are available. Note that this interface is not limited to the SBC-85 project since the port to the computer is simple TTL and could...
Switching over to an ARM based solution is much better than an AVR+RTC chipset solution. Been looking at the STM32F030 chip and it is a perfect fit for this application! It has the following very desirable characteristics:32.768kHz oscillator on-chip....
I have started to squeeze the hook code. This can be done by merging the start, stop and data bits into a 16 bit register and use the same loop to transmit all the bits from the RS232 character (i.e. 10 bits). It also has a positive side effect that...
Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...
[15:30] First, I actually sketched a 1:1 with a pencil what I was going to model. I don't usually do this. The main ideas is that there are 2 displays (since other Tetent devices would have one one each half anyway) and Finger5 would be shortened...
