WebSep 5, 2024 · Hello everyone, I'm currently trying to develop an UART application in the esp32-wrover. But when I enable the pattern interrupt, I get the UART_FIFO_OVF event multiple times, repeating at least each 2 seconds. I have tried to increase the `rx_buffer_size ` to 20KB when calling ` uart_driver_install `, this reduces the issue, but it stills ... Web3 R RX_FIFO_OVF_FLG The interrupt flag indicating FIFO overflows. 0: invalid. 1: valid. Notes: The register polarities are controlled by INT_POLAR, meaning that, when INT_POLAR = 1, 0 represents interrupt is valid and 1 represents interrupt is invalid. The registers irrelevant to FIFO are not discussed in this document. 1.2 FIFO Operating Mode
