Your issue is likely that the uart hardware tries to minimize interrupts, that is, it will wait until there is no more data incoming for a while before software actually receives the data. You could set that timeout to 0 using uart_set_rx_timeout() and see if that solves the issue. Thank you for yo...

Hello, I'm trying to use uart_echo example as the base for my code. I want to read 4 bytes (with 4800 baud rate), then transmit them back, but the problem is I get about 20ms delay between Rx & Tx. The code is so simple, but I can't understand what is the problem. Can anyone help me? I'm so confused...

Hello,

I want to start a project with ESP32 and a tft LCD with 8080 parallel interface. I know that ESP32-S2 supports 8080 parallel interface (using I2S). I was wondering if ESP32 also supports 8080 (I get confusing answers on different websites).

Can anyone help me?
