I've rewritten DevTerm keyboard & trackball firmware

DevTerm
5

I created an automatic flashing package for the new firmware
The commands are as follows

sudo apt install dfu-util -y

wget https://github.com/clockworkpi/DevTerm/raw/main/Code/devterm_keyboard/bin/DevTerm_keyboard_firmware_v0.2_utils.sh


chmod +x  DevTerm_keyboard_firmware_v0.2_utils.sh

sudo ./DevTerm_keyboard_firmware_v0.2_utils.sh

Problems and solutions

  1. usually the first time of flashing will be no response,so you need to run
    sudo ./DevTerm_keyboard_firmware_v0.2_utils.sh again, and keyboard might not woking during the first flashing, so strongly recommend to do the whole job in SSH

  2. make sure you have /dev/ttyACM0 when the keyboard is ON the devterm,in the rare cases , keyboard will be renamed to other like /dev/ttyAEM0 or else, that will cause the flashing failed,try the flashing when /dev/ttyACM0 appears

here is no response screenshot


here is flashing successful screeshot

If you want old firmware back

sudo apt install dfu-util -y
wget https://github.com/clockworkpi/DevTerm/raw/main/Code/devterm_keyboard/bin/DevTerm_keyboard_firmware_v0.1_utils.sh

chmod +x DevTerm_keyboard_firmware_v0.1_utils.sh
sudo ./DevTerm_keyboard_firmware_v0.1_utils.sh

same process

for coding/hacking tips

I only did the coding under Linux with Arduino IDE ,and I found out that, I need to use root with Arduino IDE so that the uploading process will work mostly,and I never succeeded to upload the code with Arduino in Windows,don’t know why
