Hi srt,
Serial data is transferred one byte at a time. Each byte has a specific format with a start bit, data bits, parity, and stop bits. A framing error occurs when a byte of data is received, but it is not in the format expected.
Framing errors can be caused by a number of reasons. The most common reason is that your serial port and device are configured to use a different settings. To solve this problem verify that the Baud rate, Data bits, Parity, and Stop bits all match the settings of your device.
If your settings match your devices settings, and you are still receiving a framing error, you may be experiencing noise on your serial line.
Hope this helps!
Best wishes,
