My Configuration:
PSRAM Camera Module with ESP32 WROVER (OV2640)

1 to 3 HUB Expansion Unit

ENV II Unit with Temperature Humidity Environment Sensor (SHT30+BMP280)
https://m5stack.com/collections/m5-unit/products/env-ii-unit?variant=32128295698522
Extend Serial I/O Unit (PCA9554PW)

Has anybody an Example ino for to do i get the Groove working with the CameraWebserver.

Which Board should I use, actually I use M5Stick-C -> Partition no OTA this works with the CameraWebserver

The Camera should work as a Webserver this already works. but how can i add the ENV II Unit and later a Serial I/O Modul?

I tried to combine these Codes, but I get some Errors.

The first Problem was a conflict Adafruit_Sensor sensor_t already exists in esp_camera so i changed it in Adafruit to sensor_te. But now it tells me the sketch is too big. I only added the ENV II to the CameraWebserver for now.

text section exceeds available space in boardSketch uses 2158522 bytes (102%) of program storage space. Maximum is 2097152 bytes.

Global variables use 55560 bytes (16%) of dynamic memory, leaving 272120 bytes for local variables. Maximum is 327680 bytes.

if anyone has a Solution this would be great.

thanks
