Resolved! How to Change PWM Polarity without DeInit Timer??
I have read STM32f1 Reference Manual and tested STM32CubeMx functions but have not found any solution. Is there a way to change PWM polarity without Deinitializing Timer??
STM32H753xI SDMMC data corruption with IDMA and CPU DCACHE enabled
Reading blocks from a SD card often result in corrupted data if IDMA and CPU Data Cache are enabled. I am not sure if this falls under erratum 2.1.1 of STM32H753xI. Attached are the STM32Cube project and modified main I used to run tests.The code in ...
Resolved! Can't download any STM32 related development tools (CubeIDE, CubeProgrammer, CubeMX, and so on).
As title says, it seems ST website is currently not available for downloading dev tool. I have tried different browsers, computers, networks (mobile and LAN), nothing works. I get the error message shown below:
How to implement the CAN OPEN STACK?
Hello,I am working on STM32F4 series of microcontroller. I am specifically looking for is a CAN Open stack implemented in STM32F4 series of microcontrollers. I have to interface one ENCODER .So i have to implement the CAN STACK. So how I can implemen...
Resolved! Sample code for Hyperflash with OctoSPI
We are new to HyperFlash and OctoSPI and it seems that working through the Datasheet and write my own driver from scratch will be very time consuming... Does anybody have a driver or sample code on how to erase / program a HyperFlash (S26KL512S) wit...
CAN Open stack implementation example
Hello,I am working on STM32F4 series of microcontroller. I am specifically looking for is a CAN Open stack implemented in STM32F4 series of microcontrollers. The regular CAN messages will not work for my board and the target stepper motor (with CAN O...
ADC and DMA conversion time
I am working on a project where I use the NUCLEO-L433RC-P board and CubeMX to configure the settings. The project use ADC and DMA, when I calculate the conversion time, I get a value less than 15 ADC clock cycles.I calculate the conversion time by me...
STM32L431RB Timer15 1 microsec interrupt generation. Is there anything incorrect with my timer15 peripheral configuration?
The APBCLK/AHBCLK is 80MHz. when I toggle the GPIO in the callback, the scope trace gives me interrupt generation of 2.3 usec instead of 1usec. Is there any timing limitation for interrupt generation?
Resolved! ADC CAL problem
Hi, I'm trying to calibrate the ADC3 on my STM32F303RE microcontroller. In according to the REF MANUAL, I enabled the ADC voltage regulator and then started the calibration but code get stuck in the while loop forever (ADCAL is always 1). I put the f...
