Posted on February 19, 2016 at 06:44Hi all,I am writing a program for the STM32F030 in which I want to update TIM3->CCR2 using a DMA transfer. This transfer will be triggered to control PWM waveform generation, although I have simplified the code be...
Posted on July 19, 2015 at 21:44Hi All! I am having a hard time making the communication between the audio codec and the microprocessor to work.I was able to configure the audio codec to output the audio picked up by two digital mics directly to the...
Posted on November 12, 2015 at 19:10 Hello everyone, I just started using the STM32F7-DISCO board and i wanted to start with writing a small UI app with a single image, with the image data being stored in the NOR flash. but the applicatio...
Posted on November 26, 2012 at 15:22Hi, I tried and I failed, now I'm asking here If someone please could provide an USART Data transmit and recieve example which uses interrupts (and if possible DMA for large datatelegrams ~ 5Kbyte). I'm using the ...
Posted on January 26, 2016 at 23:53Hey everybody. I`ve been browsing the forum for a while trying to solve my problems with SDHC, but I can't find an answer. I have this 4gb SDHC card and it won't initialize at all! I just can't make it work. It wor...
Posted on February 17, 2016 at 23:14 Guys, Can I use SPI1 as VS1053 and SPI2 as SDcard, It seems that after VS1053 initialized, it can not read SDcard ?? why is that ? Thanks void Init_FAT() { char FAT_cnt = 0; if ...
