如果未设置成员SPI_transaction_t::标志中的SPI_TRANS_VARIABLE_CMD和SPI_TRANS_VARIABLE_ADDR标志,则驱动程序会在设备初始化期间自动将这些阶段的长度设置为默认值。 (回头仔细看,可能有用) 如果命令和地址阶段的长度需要可变,则声明结构体spi_transaction_ext_t,在成员spi_transaction _ext_t::base中设置spi_TRANS...
1.UVC 开启 传输视频数据的时候,SPI DMA(GPSPI3) 刷屏卡住,I2S DMA 方式刷屏会花屏,ESP32S2 USB 数据量大会影响外设? 2.ESP32-S2 UVC 传输开启WiFi的时候,设备log 不断输出 phy: pll_cap_ext 10,一会后 pll_vol_cal 会引发 abort。日志见附件。测试了2块开发板其中一块(esp32-s2-hmi-devkit-1)(模...

It's not a perfect example. First, I'm only doing DMA operations. Next, I could not get QuadSPI reads to work (e.g. master/host PC reads data from ESP32S2 slave device). Writes worked fine. My work-around is to only ever use QPI mode, which firmware automatically enters during ...

ESP32-S2 External RAM / PSRAM + I2S LCD + DMAby faptastic » Sun May 19, 2024 1:16 am Hello. The TRM seems to imply that one can create a buffer in PSRAM memory, and use EDMA to send out via the I2S peripheral (for parallel output LCD mode). However, any attempts I try ...
