Hi Guys I update you, doing some debugging I found the problem uf2-samdx1/src/main.c Line 306 in 2fd0593
the problem is about usart_sharp_received () going backwards. uf2-samdx1/src/usart_sam_ba.c Line 170 in 2fd0593
the problem is about usart_is_rx_ready () going backwards. Line 177 in 2fd0593
the problem is here, however FT232R is connected with the RX / TX pins of the Metro, I also tried always on main to send a byte on UART1 (SERCOM3) with: Any suggestions |
