I used the spi_slave_transmit() and spi_slave_queue_trans() functions respectively, but all data frames could not be received normally. Therefore, I tested with the following code and found that the SPI frame interval was too short and the ESP32S3 could not receive all in time if i use...
程序使用IO12 IO14 IO15 从spi slave模式读取数据,发送到wifi指定的udp server上。 IO13(MISO)未用,所以写了-1; 程序采用spi_slave.c的例子程序修改的。 问题: 1 一开始运行正常 2 一段时间后(10-20分钟),IO12变为低电平,只有来数据是是高电平,没有数据时是低电平。(正常应该没数据是高电平) 怀疑: ...
Hardware: ESP32-C6 (dev board or any custom boards) Software: spi slave exsample Docs says: When an SPI Host is set to 80 MHz or lower frequencies, routing SPI pins via GPIO matrix will behave the same compared to routing them via IO_MUX. But in reality, when MOSI or MISO or SCLK...
