Being new to ESP32 programming in Arduino, I have tried very hard to enable verbose logging, referencing this link (https://esp32.com/viewtopic.php?t=5730) but I have had no luck (INO below). Am I missing somet
SPICOMMON_BUSFLAG_NATIVE_PINS :与 SPICOMMON_BUSFLAG_IOMUX_PINS 功能相同,表示使用本机(native)引脚进行 SPI 总线的配置。 具体可参照 spi_common.h 中的 SPICOMMON_BUSFLAG_ 配置项* intr_flags 中断分配标志可选项有: ESP_INTR_FLAG_IRAM:分配 IRAM 中的中断处理程序。 ESP_INTR_FLAG_SHARED:在多个处理...
I did find a pre-made library for the MCP3204 at: https://github.com/gfurtadoalmeida/esp32-driver-mcp320x Code: Select all #include "driver/spi_master.h" #include "driver/gpio.h" #include "esp_log.h" #include "esp32_driver_mcp320x/mcp320x.h" void app_main(void) { spi_bus_...

BOOT模式用于运行ESP32上的程序,而FLASH模式用于上传程序到ESP32。Strapping pins(引脚配置开关)用于配置ESP32的工作模式。通常情况下,带有内置USB/Serial的开发板会自动将这些引脚配置到正确的状态,以支持烧录或启动。然而,如果其他设备使用这些引脚,可能会导致ESP32进入错误的模式。
SD/MMC控制器支持两组外设工作，但不支持同时工作，其连接的拓扑结构如下所示：图37.1.5.3 ESP32-...
/* Configure SD_SPI pins: MISO */ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; GPIO_Init(GPIOA, &GPIO_InitStructure); /*!< Configure SD_SPI_CS_PIN pin: SD Card CS pin */
The ESP32-S3-DevKitC pinout uses the same pins for FSPI and SUBSPI (apart from SUBSPICS0) so I don't understand how one would wire up both simultaneously ... do you have to map one of them to other pins (using IO_MUX or GPIO matrix)?
Compiling a FastLED project with the FASTLED_ALL_PINS_HARDWARE_SPI flag enabled while targeting an ESP32-S2 board results in the following compile error: .pio/libdeps/adafruit_qtpy_esp32s2/FastLED/src/platforms/esp/32/fastspi_esp32.h:75:32: error: 'VSPI' was not declared in this scope ...
