did you ever encounter some RP2040 GPIOs just not... working? i.e. you tell it to output a logic high level, but the actual pin is close to GND? we have some pocket keyboards that are like that. there is no short on the board. so i'm wondering how this can happen. damage during soldering, handling?

@mntmn do you initialize for GPIO function? There are several registers to set, sometimes default values may change

Търсим си колега, който да програмира на C/C++. Може и с малко опит, но да има желание за учене. Предимство е ако се е занимавал с Ардуино, ESP32 и програмиране на електронни джаджи! Предлагаме работа само на място във фирмата в Пловдив. Няма възможност за отдалечена работа.
