一块esp32c3 mini模块做从机,源码为 https://github.com/espressif/esp-at ;另外一块esp32c3 mini模块做主机,源码为 https://github.com/espressif/esp-at/tre ... 2_c_series 。主从机均已将主控设置为esp32c3,使用引脚如下:
(6) SPI sclk pin
(7) SPI mosi pin
(2) SPI miso pin
(10) SPI cs pin
(3) SPI handshake pin for slave send
报错如下:
主机:
E (37299) SPI AT Master: SPI recv seq error, 1, 2
E (37299) SPI AT Master: Maybe SLAVE restart, ignore
���������E (37375) SPI AT Master: SPI recv seq error, 1, 2
从机:
I (828) at-init: module_name: ESP32C3-SPI
I (828) at-init: max tx power=78, ret=0
I (829) at-init: v4.2.0.0-dev (unknown)
E (96743) at-spi: recv wrong len: 0, 4092, 0x0
这个错误应该怎么排查?
ESP32C3 SPI AT通信不上
