  • 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...
  • 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...
  • Added A4 firmware and STL files for the case

  • The A4 firmware contains all the sub menus populated into the main menu, better adjusting precision for the voltage and currents, updated component values for calculating the voltage feedback and the current and many more. I also added another logo...
  • [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. ...
  • [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...
  • 20230219c -- ROM test file

  • 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...
  • Smooth operator

  • Put the capacitive reading code to use.Started with code from here: https://forum.pjrc.com/threads/31797-Teensy-FSR-based-MIDI-controllerAdded a calibration stage where it detects the base capacitance at startup.Modified it to use this library for smoothing...
  • 20230214a -- Memory, cont.

  • Operating under the current assumption that RAM is 32 KiB banked at address 0000-7fff, with the first 256 bytes masked off by special function registers and internal SRAM, some other code sections of interest were found.  E.g.:ED00 loc_ED00: ED00...
  • 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...
  • 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....
  • 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...
