How to change default size of UART FIFO?
Posted: Wed Feb 26, 2020 10:47 am
Hi all,
from ESP32 technical reference manual I've learned that UART controllers share a total of 1024 bytes RAM and default size per Rx/Tx FIFO is a block of 128 byte. Furthermore it says "Rx_FIFO of UARTn can be extended by setting UARTn_RX_SIZE".
However it is not clear to me, where this UARTn_RX_SIZE parameter is actually found to be adapted? Is it somewhere in IDF source? Can anyone help on this?
