Glass LCD STM32L0

Posted on April 13, 2016 at 23:25Hi,I facing problem with custom segment glass LCD interfacing which include 4 COM pin and 20 SEGMENT pin with 1/4 duty cycle and 1/3 bias (Refer Attachment).I tries to understanding HAL library provided on ST site ex...

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...

CubeMX 4.26 Timer with Input Capture doesn't turn off

Hi,In CubeMX 4.25 it worked properly then I was forced to migrate my project to 4.26 and the timer with input capture stopped working properly. If I overwrite the driver with 4.25 then it works fine again. I suspect this function is wrong: HAL_TIM_IC...

STM32F0 discovery - How to generate exact number of PWM pulses?

Hi,I am using STM32F051R8T6(used in STM32F0 Discovery). In my application I need to provide clock input to a device to read specific number of bytes at a time and stop the clock. I am currently using the idea of generating PWM from timer 1, provide t...
