  • Multi-boot Multicomp (Part 2)

  • 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...
  • Software-only solution

  • 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,...
  • muahaha, I cheated :)

  • 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...
  • How ESP-NOW really works ?

  • 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...
  • Pro Trinket and Pro Micro Compatibility

  • 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...
  • Points about using an ARM uC

  • 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....
  • Squeezing the code because 85 bytes is too many...

  • 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...
  • Z80 (CP/M) Writing to SD Card

  • 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...
  • [E2][M] First Concept

  • [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...
  • [E2] Initial extruder tests

  • So I turned off the minimum extrusion temperature so that I can send over a print without heating up the hotend first. It didn't seem like the extruder wanted to move at the start of the print at all until I tried spreadcycle mode. ...
  • Debugging

  • Debugging Need to get this project working. One problem is that the Nano does not have enough pins. So I have used a Meduino (a Mega2560 Pro Mini). Here is the schematic: Here is the PCB: The ports (P1 & P2) match the TTA8 bus. A problem with the Meduino...
  • [E2][M] Tweaks

  • First up, I want to say that the doorstop Tetrinsic shape unexpectedly helped out in this design. Thumb1 would've instersected Finger2 and Fingers2-4 would've intersected the same fingers on the other side if not for this design: Tetrinsic 2.0 didn't...
  • [E2] Extruder issues

  • So I connected power and nothing broke so that was a good sign. Thus, I connected the extruder wires and heated up the nozzle. As you can see by the title of this log, the extruder motor didin't turn when I commanded a retraction. So I got...
