For anyone having trouble suign these units, there does seem to have been an update which broke stuff.
However, it now seems to be more stable and vanilla from esphome rather than pulling off github links (thanks to those who did that code of course!)
The display driver changed wildly to use mipi_spi only.
Works with some init data.
The adc driver does not need to use fractured_blue c6_adc plugin (which won’t compile any more too) and can just go straight from the main:
esp32:
board: esp32-c6-devkitc-1
variant: esp32c6
framework:
type: esp-idf
We must also use “attenuation: auto” on adc definitions or it will not give full range (about 3-3.1V) and only give 1V range on ADC inputs
This sets a static IP, it falls over to making a wifi AP if no connection.
I have developed a PCB that has a 5V to 24V step up converter that can power 4-20mA sensors, so one can have 6 sensors on a unit. It can also take digital inputs if there is a little resistance set up.
The circuit provides a 24V output which can be sent to the sensor to power it and then the signal that comes back has a voltage divider so that 0mA=0Vdc and 20mA =3.3Vdc onto the pin.
So one sensor is converting a 0-10bar air pressure sensor and one is just volts on the input (not calibrated for anything). But it can give 6off 4-20mA inputs.
