Re: RS485 UART returns incorrect messages

RS485 is half-duplex communication, the data sent is also received, so when you finish sending data, you need to call `uart_flush_input`.
Not sure if it solves your issue

Re: Esp32 i2s parallel driver with FreeRtos

Hi, Baldhead ESP_Angus provided some good suggestions for you, also you can use queue to make two buffers work synchronously. The code can be like this: //DMA idle flag int dma_idle_flag = 0; //We used the out_eof interrupt, but the eof interrupt was not generated before the transfer started, // so ...

Hi,
The I2S DAC in the master branch is currently not working. We have refactored the driver and have not merged into the master branch (will be OK soon). It can work on release 3.3.

thanks !!

Re: UDMA Decoder and linked-list

Hi, Binogof, The encode and the decode is optional. If you don't want to use encoding and decoding, you should clear the following register: [ conf0: seper_en, head_en, crc_rec_en, encode_crc_en ] and [ escape_conf: tx_c0_esc_en, tx_db_esc_en, tx_11_esc_en, tx_13_esc_en, rx_c0_esc_en, rx_db_esc_en, ...
