Question 1

I am building a system using a Waveshare RP2040-Zero ( like a Raspberry Pi Pico ) with an HD44780-2004 LCD over I2C. I'm facing a strange issue where the text on one line of the display occasionally ...

Question 2

I am trying to communicate between 2 nRF24L01+ and am using 2 Raspberry Pi Pico's to control them. Below is my code, schematic, and the datasheet. My problem is that the transmitter always prints <...

Question 3

JLCPCB is trying to tell me that the RPi Pico W needs to be baked to reduce moisture before putting it through reflow soldering. They're saying that "It is moisture-sensitive according to the ...

Question 4

I have built a small device that fits inside an Altoids tin because it neatly fits in your pocket. In the tin: Raspberry Pi Pico 2 W 2 x Solar panels 10F supercapacitor (to power device in the event ...

Question 5

I want to get 2 picos to communicate via UART and a HC12 chip and I managed to get it to work in the past but somehow it just stopped working. Here are the 2 picos with the HC12 chip And the code just ...

Question 6

I want to use a MDDRC10 motor driver with a Raspberry Pi Pico. But I can't get it to work from the manual. As I understand it from page 3, anything over 1.5 V will activate the channel and then I can ...

Question 7

I designed a circuit for a portable infinity mirror tetrahedron. It includes a battery to power it while it isn't docked, a pi pico W to run the 6 APA102 based LED strips, some contacts on the outside ...

Question 8

I have a 2.6 in 320x320 display that I would like to drive with the Raspberry Pi Pico 2 but I am having some issues with my code that I am not sure how to fix. I am not quite familiar with this ...

Question 9

I've written a simple program the transitions GPIO0 and GPIO1 high to low and low to high "at the same time". The board is powered over USB and not connected to anything. I've got my ...

Question 10

I want to use a nRF24L01 module with a pico but I geek on getting an error that the Hardware is not responding. I followed this video for the pinout: and the code is: ...

Question 11

I am designing a board that will be required to switch on many relays, hence I am using TPL9202 to do the work. I have validated the psuedo-circuit on a single TPL9202 on a breakout board and it works ...

Question 12

Basically I have a connection like this. My processor is a rp2040. And when I tried to read the voltage like this: ...

Question 13

I will preface saying that this is my first time posting here so please forgive any obvious mistake I could make. I am in the process of designing a PCB for a simple terrarium control system. Mainly, ...

Question 14

I am working on a project, where I have a Raspberry Pi Pico and then a DS1302 chip to keep time when the pico is not powerer. The whole thing is powered by a single lithium battery. The battery powers ...

Question 15

This question arises from a confusion about theory and seeing successful projects online. I want to connect a DFPlayer Mini MP3 module and a speaker to a Raspberry Pico Pi 2 microcontroller and it's ...
