Hello ,
I 'm trying to start working with HT-CT62 , and lookin for info about the Shell Schematic ( [ESP32 Dev Backplane] , seems that there is no available in the heltec web.
I’m unable to get working the I2C , an looking for pin conflicts with the shell… anyone can help ?
Thanks "!
This is the actual place for all Heltec documents: https://resource.heltec.cn/download/
If I’m not mistaken, this is the right file for the ESP32 Dev Backplane: https://resource.heltec.cn/download/HT-DEV-ESP/HT-DEV-ESP_V3_Sch.pdf
But of course have a look for yourself there as well
Steven , thanks for the fast feedback , yes it is the schematic.
Now I’m taking a look , but seems there are not much pins available , I’was thinking on add SPI and I2C for test…, anyone was successful with this ?
I’m trying to use GPIO 18 & GPIO 19 for SCL & SDA , but it doesn’ t work , and these pins seem not used …
Thanks ,
