Hi,
I'd like to ask whether it would be difficult to modify micropython source to enable hw flow control on esp8266 board.
You can see, that the board has hw flow control - e.g. here https://www.esp8266.com/viewtopic.php?f ... 60&start=8
In uart.c (https://github.com/micropython/micropyt ... 266/uart.c) there are some signs of probably turning it off... (at least on RX side):
WRITE_PERI_REG(UART_CONF1(uart_no),
((0x10 & UART_RXFIFO_FULL_THRHD) << UART_RXFIFO_FULL_THRHD_S) |
((0x10 & UART_RX_FLOW_THRHD) << UART_RX_FLOW_THRHD_S) |
UART_RX_FLOW_EN |....
....
Maybe it is possible to just hardcode to enable it and compile micropython for my usage... but I'm not sure if it is so easy...
Anyone can help, hint, please?
