Sounds like a manufacturing defect or an error with the soldering.

Ai-thinker is a well-known manufacturer. But from the pics of AiPi-CAM-D200, it looks like it may not fully match the specifications of ESP32-CAM.

Thanks a lot for sharing. I used this red display a couple of times but such an idea never came across my mind. It looks really beautiful.

Ensure that the "spi.h" file is located in the correct directory within your project structure. If it's not, move it to the appropriate directory.

Experiment with different durations for deep sleep to see if the behavior changes.

Run an I2C scanner sketch on your ESP32 to confirm that it detects the LCD at address 0x27. If it doesn't detect the device, there might be a wiring or communication issue.

Using the wifi_fpm_do_sleep() function with a sleep duration of 0xFFFFFFF will effectively put the ESP8266 into deep sleep mode indefinitely until it receives a reset signal. You can use the timer wake-up from deep sleep: https://randomnerdtutorials.com/esp32-t ... eep-sleep/

The ESP32 chip itself supports this component. Its functionality may depend on the specific version of the ESP-IDF you are using and the configuration of your project.
