How i can connect humidity sensor to CB1 with Manta M8Pv1.1
Due to lack of documentation, I can't figure out how to connect the I2C module to CB1. Perhaps this is not so much a ratOS problem, but simply the lack of normal documentation from BTT. I connected it now to
17 3.3V
19 PH7 GPIO231, SPI1_MOSI (DA)
21 PH8 GPIO232, SPI1_MISO (CL)
25 GND

Try to reconnect it to PH6 PH7 ?
a quick google search and I don't see a BTT I2C humidity sensor. Where did you get it?
I have a HDC1080 i2c module
It must be I2C Address 0x40
Also as HTU21D
Just want to connect it to CB1 GPIO
This is if you connect to M8P v2.0, and I have M8P v1.1
is the klipper config for setting up a HTU21D

doesn't look like the 1.1 has a i2c connector
That's partly why I'm asking how to connect it directly to the GPIO (40-pin connector) and initialize the rPI MCU as an additional klipper device
if you want to connect it via the GPIO pins you will probably have to write custom code to get the data you want and integrate it into klipper. Klipper is expecting it to be connected to a i2c connector
I understand how to connect it to the clipper, in principle, but now I can’t make it display on the i2c bus yet
