QSPI is not currently supported in arduino, so can only be enable using the ESP-IDF drivers. If you aren't using those pins for QSPI, you should be able to use them for whatever you would like. Perhaps your board is using gpio 14 for something else, or has additional hardware ...

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...

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...
It starts by opening /dev/input/ to find a device that has a name: gpio-keys-polled (this name is obtained using ioctl call with request EVIOCGNAME). Then, it will start a thread (using pthread) to poll this device. The power button is a separate device from all other buttons, and ...
in an efficient embedded-friendly manner.5Usually, most of the features of a module will be available, but aspects that are considered edge-cases or redundant in an embedded context will not be implemented. All versions of MicroPython come with modules for interacting with the hardware, GPIO (...

GPIO testing Rockchip RK3588 is supposed to have five GPIO banks numbered from GPIO0 to GPIO4, but I can see six in the Debian image: $ ls -l /dev/gpiochip? crw--- 1 root root 254, 0 Jul 20 07:50 /dev/gpiochip0 crw--- 1 root root 254, 1 Jul 20 07:50 /dev...
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 Posts: 3529 Joined: Tue Dec 01, 2015 7:35 am Re: ...
