你好,我现在首次使用esp32-s2这款芯片,使用的esp-idf进行开发,我查看esp32-s2_technical_reference_manual_cn.pdf这个手册,里面对交换矩阵有一个表的描述,但是我发现了不太对劲的问题。 截屏1.png这里写的是ws信号不能通过io mux输出,但是我再GitHub上找到的一个参考程序,却可以这样配置并正常使用 截屏2.png,...
Oh, the technical reference manual notes that the DMA channel is shared. So I guess it's a hardware limitation? GP-SPI3 is also a general purpose SPI controller, but shares a DMA channel with ADC and DAC modules. GP-SPI3 works as either a master or a slave. As a master, GP-SPI...
However, to get better performance, we would like to use DMA mode. This requires us to setup the DMA descriptor. As per technical reference manual, the desciptor needs to be in internal RAM. Data can be accessed from external RAM.

打开ESP32-S2 技术参考手册 (“esp32-s2_technical_reference_manual_cn”),可以看到下图: ESP32 S2的Arduino 环境对于 SPI 的定义是有问题的。 ESP32 S2 SPI框图 对于S2 这个芯片来说,有四个 SPI,其中“SPI0 和 SPI1 仅供内部使用,通过仲裁器共享 SPI 信号总线”。因此,对于用户来说,只能使用 FSPI(GP...
