Как из аппаратного цифрового входа, сделать цифровой выход? Схема с внешним транзистором «костыль»
Занимаюсь проектом, на модуле ESP32 не хватило выводов! Не особо хотелось применять расширители портов на PCF8574 и ей подобные, в связи с чем пришлось городить костыль.. DevKit v1 на базе ESP-WROOM-32, на своих выводах (pins) имеет GPIO сконфигурированные только под цифровой вход, т.е. Input! Но ни как Input/Output. Это порты: GPIO34, GPIO35, GPIO36 и GPIO39.
Looking for recs for breadboards / wiring kits for adult beginners!
It's time I finally dive into the hardware end of things, I have some odds and ends lying around I've been meaning to tinker with

Expected to create a 10us pulse in python using time.sleep() on my raspberry pi:
GPIO.output(pin_trig, GPIO.HIGH)
time.sleep(10E-6)
GPIO.output(pin_trig, GPIO.LOW)
Only to see a 95.5us pulse with my #siglent scope
ESP32-P4 + ESP32-C5 board features Raspberry Pi-compatible MIPI connectors for official displays and camera modules
We've come across an ESP32-P4 + ESP32-C5 board that looks similar to the Wireless Tag WTDKP4C5-S1 board, but is even more compact and features four MIPI connectors, including two whose pinout is compatible with Raspberry Pi camera modules and displays. Maker Go calls it the "ESP32P4C5 core board" and features an "ESP32-P4-Module" with ESP32-P4 MCU with 32MB PSRAM, an ESP32-C5 dual-band WiFi 6 SoC, nd a 16MB NOR flash. Besides the MIPI connectors, the board features three USB ports, one for debugging, and two Type-C/A ports sharing a USB 2.0 data connection, a built-in MEMS microphone, a speaker connector, and two 34-pin headers for expansion. ESP32P4C5 Core Board specifications: Main SoC – Espressif Systems ESP32-P4 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz with 8KB of zero-wait TCM RAM
Потоковая запись ADC семплов на STM32
В этом тексте я показал как настроить потоковую запись ADC семплов на микроконтроллере STM32. ADC модель это основа любого электронного измерения. Основа любого DMM. Всё что за корпусом микроконтроллера - это аналоговый мир. ADC это портал который позволяет аналоговым сигналам просачиваться в мир цифры.
