I had not come across a FSPIWP pin (GPIO14) on an SPI bus before, and although its mentioned in the ESP32S3 datasheet I cannot seem to find an expalanation of what its for. If your using SPI do you have to leave the FSPIWP pin unused ?
We are using a ESP32 WROOM module and the design uses a "power enable" signal to keep the power supply turned on. This is wired to GPIO21 on our ESP32. I set this pin high at start up using a bootloader hook, to make sure that the power supply stays on. It's also set high ...
Today I tried with ESP-IDF v5. and after checking the wiring 2 times, it does work correctly with an SPI SD card module and a 16 GB card: Code: Select all I (316) example: Using SPI peripheral I (316) example: Mounting filesystem I (326) gpio: GPIO[10]| InputEn: 0| OutputEn...
It would help if I could find the c code for gpio_matrix_in and gpio_matrix_out. I have searched the esp/components folder and cannot find the source code for these functions. They are not in gpio.c. Where is that code? WiFive ...

Breaks out GPIO,power, and serial pins on popular ESP32 WiFi/BT module. 0.1″ pitch castellated connection pads for easy breadboard use. USB-serial interface eliminates need for FTDI cable. Ready to load MicroPython firmware out of the box. ...
Multiplexers, both GPIO: input, output, Analog: input, output if you can find any (I don't teach this yet) Other IOT connectivity examples such as websockets, MQTT connectivity, LoRa and LoRaWan, Radio etc After all these examples are working we can say that the new board is mcu-stable...
But in case you’re working with resistors, LEDs, or other components that usually won’t work unless you physically solder everything to the GPIO pins, then breadboards can save you the pain of desoldering everything when you make a mistake or decide to build a new project. How to ...
But it has GPIO for low level output and sensors. The logic side of my arduino home automation project is a AMP stack (currently WAMP) and I think I might use the Arduino as the PHP server for it. For $35 its not bad. My usual boring signature: Something Reply With Quote Jun...
