I’m trying to install esphome and I’m experiencing very poor camera image quality (the horizontal line is scanning from top to bottom and the vertical lines seems to be sync lines).
The demo application that came with the device had much better image quality, so I’m reasonably sure it’s not the hardware.
Here’s my yaml config, it’s based on the official example (m5-docs):
esphome:
name: atoms3r-m12
friendly_name: M5Stack AtomS3R M12
on_boot:
priority: 800
then:
- lambda: |-
gpio_set_direction(GPIO_NUM_18, GPIO_MODE_OUTPUT);
gpio_set_level(GPIO_NUM_18, 0);
vTaskDelay(pdMS_TO_TICKS(1500));

Here’s an extract from the build log with issues:

Things I already tried:
- Changing up and down clock frequencies
- activating/deactivating aec/agc, changing aec/agc settings
- changing brightness
- Messing around with the lambda (this got rid of the “Recovery: failed, SCL is held low” but the camera issue remains):
// 1. Enable I2C/Sensor Power (GPIO18 LOW)
gpio_set_direction(GPIO_NUM_18, GPIO_MODE_OUTPUT);
gpio_set_level(GPIO_NUM_18, 0);
// 2. Hardware Reset the Camera (GPIO38)
// The sensor needs a LOW pulse to reset properly.
gpio_set_direction(GPIO_NUM_38, GPIO_MODE_OUTPUT);
gpio_set_level(GPIO_NUM_38, 0); // Reset active
vTaskDelay(pdMS_TO_TICKS(100));
gpio_set_level(GPIO_NUM_38, 1); // Reset released
// 3. Give the hardware time to stabilize after power-up
vTaskDelay(pdMS_TO_TICKS(1000));
- Disabling sensors
- trying different usb-c wall chargers
Any help in fixing the issue would be appreciated.
