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 17, 2017 at 10:28Hi,I'm trying to implement some audio processing functions for my mp3 player project based on processing libraries provided by ST, but I have some problems getting that to work. The UM1798 Audio engine post-proce...
Posted on September 07, 2017 at 13:04Hello,to achieve a SIL2 by using a STM32F4 MCU a periodical core self-test is required. So the CPU itself and the FPU shall be tested. STM is giving us the manual 'UM1840: STM32F4 series safety manual' (http://ww...
Posted on September 05, 2017 at 17:33Hi !I am currently designing a test plan for my software/hardware application. During the tests, I need to know if the ADC is functionnal and correctly calibrated.We have an idea to test it with an hardware solut...
