Hi, I'm trying to figure out the reason behind the NOP in ESP32 uart_ll_read_rxfifo https://github.com/espressif/esp-idf/bl ... _ll.h#L203 Is this related to esp32 errata 3.16 ?szmodz Posts: 8 Joined: Thu Mar 21, 2019 10:11 am Re: esp32 UART FIFO read...
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1200588/tda4vm-uart-fifo-settings-clarification 器件型号:TDA4VM 您好、TI 支持团队、 您能否在 UART 的以下几点上提供支持。 1.根据参考手册第"12.1.6.4.6.3节 FIFO 轮询模式操作"部分 FIFO_EN 位已关闭,但我们怀疑...
With the multibyte read "success" in mind, I'm going to try out a solution / workaround. My next plan is to replace the single byte read function with a UART_RCFIFO_REG check. If > 0, then I'll read in that number of bytes immediately, and set the timeout to (N * intercharac...
DAC8740H 只有 UART 接口、不使用 FIFO。 MOD_IN (或 MOD_INF)上传入的数据将放置在 UART_OUT 上、而来自 UART_IN 的任何数据都将放置在 MOD_OUT 上。 FIFO 在 DAC8741H 中实现、并通过 SPI 通信访问与 HART 或 FF/PF 的通信、以到达基于寄存器的 FIFO。 吴约瑟 ...
It seems that when calling uart_read_bytes() the hardware FIFO buffer is not flushed, see this thread. This causes problems when you need to quickly react to events, such as the UART_PATTERN_DET event. It causes the following issue: I ha...
