Posted on March 06, 2017 at 05:17I want to generate simple audio waveforms and send them out through the headphone jack, preferrably using a synchronous interface such as HAL_SAI_Transmit. (I know there are better/more efficient ways to do this whic...
Posted on September 21, 2017 at 13:19 I spent 3 hours debugging this. I'm using STM32L051 with FreeRTOS (initial code generated by STM32CubeMX v4.1). GCC version is the one that's coming with Ubuntu 04 by default: ~$ arm-none-eabi-gcc --versio...

Posted on September 22, 2017 at 07:26Hi All,I have a problem after adding a new interface for stm32 USB-CDC. I receive wrong data after sending about 1250 bytes. My code has:a) Two interfaces generated from STM32 CubeMX: . the first interface ha...
Posted on September 20, 2017 at 23:41Hi,I am trying to add the ADC handles into a struct that is in a seperate header file. For some reason I cannot get the ADC handles' typedef to be located after including stm32f4xx_hal.h.My struct looks is as fo...

Posted on September 14, 2017 at 13:50I'm using STM32f4-Discovery board for an audio application.I'm using the onboard codec CS43L22, in analog passthrough mode. But I'm getting high frequency noise on the output over headphones.Can anyone tell what ...
Posted on September 05, 2017 at 15:17Hello,I am working with stm32f4 discovery and linux systems.We have a larger number of discovery boards that are interfaced via USB, and want to be able to connect to each one uniquely. I normally do that by usin...
