WONDER! .. i was following controller tech video from the last year for my project and today i heard my village Dwarahat songs.. thanks now i don't need any extra tab to play kumoni songs ...
got quite a lot of errors: ----Core/Src/sysmem.c:38:1: error: unknown type name 'caddr_t' ----Core/Src/sysmem.c:51:25: error: 'caddr_t' undeclared (first use in this function) ----Core/Src/sysmem.c:56:25: error: expected ';' before 'prev_heap_end' What is wrong?
Hi nice tutorial ! Is it possible to stop a sound clip in the middle and play another random selected clip ? Like for example if I am playing 1.mp3, can I stop 1.mp3 and play 4.mp3 ? Also is there any way to understand if a clip is completed playing ;flag pin etc ?
You can try yourself. Also check the datasheet for different sets of commands. It shouldn't be difficult. You already have a base now and u just need to add things to it
Amazing job! I'm working on a design that will use SD card with file system and SPI with DMA to read PCM audio to a DAC. A peripheral to peripheral mode. The hope is the DMA controller can handle transfers while the main loop is running. I wonder if you think this a feasible approach.
Hi, are you going to match you ADC with the PCM bitrate? If you is somehow possible, but really doesn't make much sense, you losing any chance to apply some filtering or more interesting signal processing. If you intend to use some ST32F1, your DAC probably is 12bits, PCM with medium quality is 16 bits, so you can't do it directly.
@Nhân Cao Anh anh ơi, anh có thế cho em cách liên hệ với anh được không ạ, em có vài vấn đề muốn tham khảo anh về cái phát file WAV này á anh, mong anh chỉ giáo giúp em với ạ?
@@ControllersTech I want to play mp3 files from SD Card through SPI communication using STM32 but I don't know how to do it. I saw your video about play WAV file but it used USB. Beside, I want to know how to decode mp3 file.
