I've been recently trying to implement code to display the time in hours and minutes via the UART terminal. I've run into the issue where the time is inaccurate and increases by a minute every second and am not sure what is wrong with my code. I use ...

I recently created a digital potentiometer breakout board for the MCP4541-104E/MS, where I would set the resistance value dependent on a particular wiper value. Here is the schematic and layout (I changed the pullups from 10k to 4.7k): Here is the c...

I have a program that displays the current temperature of a room on the UART terminal and I want to start getting into the habit of separating my functions into their own source and header files, however, I'm running into a couple of problems. Here i...

I have a custom PCB I designed where I intend to use UART via PuTTy, however, I'm not entirely sure how to do this through the cube IDE. Normally with the Nucleo L476RG, the device is recognized and I upload code via USB, however, I need to flash the...

I recently wrote some code with the help of stack exchange regarding an MQ2 gas sensor. I needed to alter the code to use DMA as the MCU I'm using for the project only has one ADC channel. My goal was to measure the ADC value of the MQ2 sensor along ...

I got it to work but changed the command address from 0x00 to 0x01 for the set time and get time function.

I read the file wrong, yes it is the main.c and not main.h silly mistake...Extern variables make a lot of sense, I knew there was a way to call the functions from the main in separate c files but didn't know how. Thank you very much!

I got it to work! All I needed to do was set the BOOT0 Pin high when uploading the code, then in PuTTy set it to COM4 with a baud rate of 115200 b/s. After that, by hitting the NRST pin I can display my text on the UART terminal! I still don't know i...

There's no way I can directly upload code via USB for my device on STM32Cube IDE? That was my original intention with this board as I wanted to upload code without having to use the ST-Link every time and read it from PuTTy. The device was able to b...

I see, what books or courses do you recommend I take? I was thinking about taking a programming class that teaches C, but maybe I'd be better off taking something that involves Embedded Engineering instead.
