How to flash firmware
Use esptool in python to flash firmware on esp.
Press flash button and reset and then release first reset button to get in flash mode
Flash command für precompiled Firmware oben
esptool.py -p /dev/tty<SERIALPORT> write_flash 0x00000 0x00000.bin 0x10000 0x10000.bin
or with newer versions of esptool (e.g. 0.4.6 on debian): esptool -ca 0x00000 -cf 0x00000.bin -ca 0x10000 -cf 0x10000.bin
How to flash .lua files
Use for example the nodemcu-uploader:
nodemcu-uploader -B 115200 upload *.lua
Beware: The tool will not tell you that lines are too long and can not be uploaded but instead throw some error messages you do not understand and exit... The solution is to remove the comments at the beginning of the file before uploading or split them up.
Todo
- Add schematics of current setups for elektrinkkammerl and scannerraum
- Add more doku on how to flash and import the scripts
- Design a breakoutboard with standardized connectors for I-button, and relays
