Hello,for acquiring Data I run a timer that does a I2CRead with DMA transfer and using a ISR for averaging HAL_TIM_PeriodElapsedCallback -> HAL_I2C_Mem_Read_DMAHAL_I2C_MemRxCpltCallback -> "Ava-Function"/Lowpassfilter"AvgCnt ==16" -> "Schedule a Task...
Hello, I recently tried to use a stm32 controller as an full speed USB host to communicate with low speed devices over a full speed hub. To my regret I had to figure out that the stm32 controller have issues with the Preamble PID which makes communic...
I would like to implement in-firmware firmware upgrades. E.g. I send the binary data to the running device, it checks it and saves it into flash bank not currently used. After saving the firmware itself, I save to flash a byte with info on which firm...
Enumeration seems correct, I can select the audio device on the PC, but mem[] buffer is not filled if I send audio to the device. If I set the exact same settings for a F407 or 411, the mem[] buffer is filled by the incoming stream.I searched a lot w...
I got the AAC decoder LIB from STMicroelectronics for an M4 processor.I need to decode MPEG4 LATM (DVB-S) audio.Is there an example program that shows me what exactly has to be in the "DSI" data and where exactly does it come from?The documentation s...
