Uart driver with transmit buffer & interrupt

[tve]

Does anyone have some code to buffer uart output (TX) and send characters to the uart using an interrupt? The driver in the AT demo only uses interrupt for RX. Thanks!

BTW: does anyone know how deep the uart TX fifo is?

I will update a uart buffer and interrupt instruction.
The UART tx/rx FIFO depth is 128 bytes.

Cool, thanks, looking forward to it! I fixed-up the uart.c that comes with the FreeRTOS SDK (https://github.com/jeelabs/esp8266-brid ... ver/uart.c if anyone cares) but stopped short of adding TX interrupt support. I'm using 115200baud and I realized that with a 128 char buffer I can simply delay for a tick (~10ms) if the HW buffer is full 'cause the buffer holds ~11ms worth of data.

Nice, thanks!
