AM3359: PRU 9-bit UART

Part Number: AM3359

Hi all,

I'm investigating ways to interface a AM335x with a 9-bit serial protocol.

I knew that the AM335x doesn't support 9-bit data through the UART hardware and PRU-ICSS's UART.

However, when I read the thread below I seem to be able to do with PRU-ICSS.

Please teach me whether I can realize it.

Best regards,

Sasaki

Hi,

This may be possible, depending on your requirements, however there are no ready examples for this. You will need to write the software by yourself. This may be useful: processors.wiki.ti.com/.../Soft-UART_Implementation_on_AM335X_PRU_-_Software_Users_Guide
