esp32c3 > gpio > mapping spi2 pinsby BugSimpson » Tue Dec 17, 2024 9:34 am Hello community, I'm trying in vain to get the pins from the SPI2 interface to the pins specified in the source code. What have I forgotten? Code: [Select all] [Expand/Collapse] gpio_pin_map_to_...
Since there are so many analog input pins, it would be good to convert it to a digital pin. I've tried this but it doesn't work for the ESP32. Is this still in the works or it isn't possible?WiFive Posts: 3529 Joined: Tue Dec 01, 2015 7:35 am Re: Pin mappingby...
Therefore, when using any one of these pins as a digital input pin, we need to connect an external pull-up or pull-down resistor. GPIO34 GPIO35 GPIO36 (VP) GPIO39 (VN) Check this tutorial: How to use push button with ESP32 Note: The maximum operating current which GPIO pins can ...
pin mapping issue, I confirmed that all the pins do not conflict with any C3 core functions (but a second set of eyes is probably a good idea). I am going off of the Version 1.1 C3 datasheet from Espressif - which does seem to have a few conflicts in the pin table. Cross posted ...
