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: ...
What is the difference between gpio modes OPEN_DRAIN and OUTPUT_OPEN_DRAIN?by mchahn » Thu Nov 11, 2021 1:47 am Aren't all open-drain pins output pins? I have i2c pins (with pull-ups). Which should I use? I'll assume I should use OUTPUT_OPEN_DRAIN for now....
Re: What's the difference between ESP32-S3-WROOM-1 and -2? PostbyESP_Peter»Thu Jan 06, 2022 1:59 am Hi kartg0058033, The GPIO35 ~ 37 is used by internal Octal SPI PSRAM/Flash, when you use ESP32-S3-DevKitC-1-NxR8V (with ESP32-S3-WROOM-2) and ESP32-S3-DevKitC-1-Nx...

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 ...
Here are some common terms that we will use in microprocessor field. Bus A bus is a set of conductors intended to transmit data, address or control information to different elements in a microprocessor. Usually a microprocessor will have 3 types of buses : Data Bus, Control Bus and Address ...
AFAIK power should be good. It comes from the FTDI (probably fake) USB-TTL adaptor and is 3.5v. On the reset pin I have a100n cap to gnd, a 10k pullup to vcc and a 330 connection to gpio16. Reset seems to always work. in the sense that the boot (after deep sleep) always sta...
Microcontrollers are very small computers, however, they don’t have large volume storage. Also, they have no peripheral devices that can be plugged in like normal computers. The Raspberry Pi Pico comes with GPIO pins, which is similar to a Raspberry Pi computer. This means you can use this...
My Network Firewall / Gateway / proxy / MQTT server is a tiny nanopi (need to be replaced but I want something as power efficient that can also handle TVhat tuner. My wifi gateway is a Gl-inet / openwrt device. My GPIO servers (IoT) a...
