This is connected to one of the adc inputs of the ESP32 (set to 12 bit width and atten_11db). Taking adc data every 1 second which is published via MQTT (using the mqtt_as) to a broker. A ...

Re: Interfacing with industrial PLC and HMI

Re: Cannot erase flash, ESP32
Can you add the --chip=esp32 to the erase_flash option? These are the commands I . usually use: esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flash esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z 0x1000 esp32-20190125-v1.10.bin It is possible that the download of the fir...
