Hi guys,
I've been trying to get this code working for the past week now and i'm out of ideas. I'm trying to control the ws2812 LEDs with PWM. These LEDs have tight timings and require a single 800kHz data...

Hello again,
Im decided to switch my first project stm32 from the HAL driver library to the SPL. I was able to get a blinky program working using the STCubeMX software and Kei1 with the HAL drives, but i wa...
Posted on May 21, 2015 at 03:46Hello,I bought a ST link v2 and stm32f103 dev board from ebay (http://www.ebay.com/itm/331348706014?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT) plugged up the st link to the header on the board as such. s...
Posted on June 03, 2015 at 03:10Hi clive,Turns out my code has been working all this time. The LED wasn't light up cause it was burnt out, and the myDAQ scope i was using didnt have a high enough sample rate. The max frequency it could handle was 40...
Posted on June 01, 2015 at 19:23Hi clive,the USART output was just for debugging. My plan is to eventually move to a circular buffer, but i haven't read up on them yet, and im not sure how to implement them with DMA.Since im not getting the 800kHz s...
Posted on May 27, 2015 at 02:38I see. This is my first time using DMA so i'll have to read up on that later. In the mean time i need to figure out how to get the PWM wave working properly for these LEDs. Thanks so much for your help!
Posted on May 27, 2015 at 02:07Thanks clive1, I knew it was something stupid! Is there a reason why you would not recommend the TIM2CH3 and DMA1CH1 combo? is there another combo you would recommend? Edit: Just for clarification for other users, the ...
