racemaniac Fri Apr 22, 2016 6:55 pm Just a little brainfart i wanted to post here . I wanted to see how fast DMA could drive the ports, so i set up a DMA memory ..
Rintin Thu Dec 15, 2016 1:14 am Hi, I needed to detect if a button is pressed once, twice or long. For this I wrote the attached code. The used pin is configured ..
stevestrong Sat Nov 11, 2017 8:22 pm Hi, just for fun: (the real sound is much better than on the video ) It is exclusively timer based, so all 4 timers are reserved, ..
stevestrong Sun Oct 29, 2017 9:20 am I have a project in which I need some short sound effects, without reading WAV files from SD card. To output PWM audio, current ..

Vassilis Mon Aug 17, 2015 5:37 pm Today I received my new STM32F103VET board and I tried to test the DAC feature. I did a quick search on this forum but I didn’t ..
petertumler Thu Sep 24, 2015 10:58 am Hi, I’m trying to underclock a STM32F103 (Maple Mini) to 48MHz (for energy efficiency reasons). According to the datasheet ..
Rick Kimball Thu Jul 14, 2016 5:21 pm A while back I had created a template based ring buffer (circular buffer) using C++ templates for the msp430 mcu. It was faster ..
Slammer Wed Apr 13, 2016 11:58 pm I miss very much the old-school printf() function…. I am tired to write again and again Serial.print() commands to display ..
