We're using a STM32L4a6 with an ABRACON 32.768KHz crystal (ABS06-127 which is on listed in AN2867 as a compatible crystal) however we seem to be observing error in to order of +200ppm (not the +/-20ppm given in the crystal specs). Using 1p2F caps an...
I am working on STM32L476ZGT6 EVAL-Board for transferring data on the SPI to one of the audio codec which is SPI slave. I am trying to read the data from codec at 20 MHz SCLK. I am seeing that the data is getting right shifed 1 bit for of every byte....
Hi forum.I have a question regarding the STM32L496G-discovery board. I want ADC1 to sample PC4 located on the on board Arduino connector, take 10 samples for this example and have the DMA xfer these to memory. I have a CubeIde project set up and have...
Hi,I'm trying to program code into custom PCB with STM32H7B3.I was first able to connect to STM32H7B3 (read Device ID etc.), but after flashing, the target cannot be found!ERROR: STM32: Connecting to CPU via connect under reset failed.I created code ...
On the STM32L0 I have a callback defined based on RTC alarms. In parallel I have a number of external interrupt (EXTIs) . Scenario Callback function is running due to RTC Alarm interrupt. Now EXTI is triggered as well (or visa verse -> EXTI function ...
Hi all,I am working with the ADC of the STM32G484 microcontroller, and I would need to have two different reference voltages, in order to gain resolution.I can't find anything about this in the datasheet, so it leads me to think that it is not possib...
Now that there is an STM32 cpu chip with larger on-board memory, I would like to make use of it, but I have not found any working examples in that line. Reading the SRAM module in the HAL driver section is not much help.
