||
| **Description:** This error typically occurs with IR camera modules and similar specialized cameras. | ||
| It happens when the camera module is still initializing or calibrating itself, but `viam-server` is already attempting to read frames from it. | ||
| This can also be caused by I2C communication issues between the board and the camera module, particularly on Raspberry Pi 5 systems. | ||
|
|
||
| **Solution:** Try one of the following approaches: | ||
|
|
||
| 1. **Reduce the refresh rate for I2C cameras**: | ||
| For I2C-based cameras (like some IR modules), try setting the refresh rate to a lower value (for example, 2Hz instead of 4Hz). | ||
| This can help with I2C bus timing issues, especially on Raspberry Pi 5 systems. | ||
|
|
||
| 1. **Check physical connections**: | ||
|
|
||
| - Ensure the camera module is properly connected. | ||
| - For I2C cameras, verify that the SCK (clock) pin is properly connected and not shorted to ground or power. | ||
| If the pin has been shorted, this can permanently damage the hardware. | ||
|
|
||
| If these steps don't resolve the issue, check your machine logs for additional error messages that might provide more specific information about the problem. | ||

This error might not be generic to all i2c IR cameras - we only have the one module using adafruit's APIs.
It's also mine, not viam official. https://github.com/randhid/waveshare-thermal. Do you want me to just put this guide in that readme?

Ahh okay yeah that sounds good 💡 I will close this PR
