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 something?I tried adding the following to my SPI setup:...
I am new to the ESP32 and electronics design in general, so please be patient with me. I am trying to use the PICO-V3-02 with a display (specifically an SSD1351) controller connected via 4-wire SPI. However, I cannot seem to figure out the SPI configuration of the Pico-v3-02. It...
In the Pin Layout section (2.1) of the datasheet, Pins 19 and 20 (SPIHD and SPIWP) of the ESP32C3-FH4 are labeled as NC (Not Connected). However, in the table in section 2.3, they are designated as default GPIOs. I tested using them as outputs, and it worked for me, but ac...
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。 具体而言,Strapping pins是一组用于配...
I have seen here that CS pins may not work: https://www.esp32.com/viewtopic.php?f=1 ... SPI#p45176 I have on default SPI pins (VSPI i guess) a SD card connected. I would prefer not having multiple devices on the same bus, but maybe its the only solution. Do you have any ...
This example is supposed to work together with the SPI sender. It uses the standard SPI pins (MISO, MOSI, SCLK, CS) to transmit data over in a full-duplex fashion, that is, while the master puts data on the MOSI pin, the slave puts its own ...
I would like the following command to work: esptool.py --chip esp32s3 write_flash --spi-connection 19,20,9,35,47 0x0 storage.bin Describe alternatives you've considered I've tried to run the command above but it complains the pins are above 31 Additional context Is this something I ...

I am trying to connect the ESP32 Thing from Sparkfun to 3 SPI slaves (ADCs) but I am not able to finalize my pin assignment regarding the Slave Select (SS or CS) pinsCould I do the following: GPIO 23 -> MOSI GPIO 19 -> MISO...
