Analogue input 40mv out.

Hi I am using a stm32L433 100 pin with an external 2.5v reference chip connected to vref+. I have tried placing a voltage (tried different values) onto one of the a/d channel, but the result is 40mv low. I then programmed the D/A , which uses the ...

ADC and Asynchronous clock mode?

Hi guys. I designed a simple PCB for measuring the battery voltage of a biomedical instrument. But I faced a simple problem. I use HAL to generate the code. So when I set the ADC clock in Asynchronous clock mode the while(1) is not executed!!!IS it b...

Is Full Duplex Possible with DMA and how to use it with CubeMX

Hello there,up to now i have used an Audio DAC on a STM32F407 with DMA and Half/Full Transfer Interrupts with CubeMX. So far so good.But now i am a little bit confused. As i have read some Posts it seems that it might be not possible to use Full Dupl...

When choose the same timer / different channels vs another timer?

Hello, I am seeking more clarity on the usage of different STM32 timers vs possible usage of a different channel in the same timer when there is need to share resources in MCU. My chosen Cortex M4 MCU has many timers but sharing pins for input captur...

Sample projects for TRUEStudio for the STM32L4R9I Eval board?

I am just starting with the STM32L4R9I Eval board (moving from a Kinetis CM4 processor). I would like to try TRUEStudio. I've downloaded STMCubeL4 and the latest TRUEStudio 9.01 but don't see any TRUEStudio sample projects in the STMCubeL4 firmware p...
