Problem: Incompatible connection on UART/SPI/I2C or Data transfer via UART, SPI, or I2C is unreliable, with occasional data loss or corruption.
Make sure to configure proper clock settings and work between devices, especially over SPI and I2C.
Check for signal integrity problems such as reflections or crosstalk, by using termination resistors or appropriate shielding.
Ensure that the baud rate, parity, stop bit, and other communication settings are consistent between the transmitting and receiving devices.
Use error checking techniques such as checksums or CRCs to detect and correct corrupted data.
