Hii would like to use the backup SRAM of the STM32F407 MCU to share boot flags between the bootloader and main firmware.The flag should be used to signal a "boot into bootloader" requested by the main firmware.To boot into the bootloader the main fir...
I am using the STM32F302R8 for motor control application. Need to do pulse-by-pulse current limiting.I have a BLDC drive board that has a comparator that can be used to give shutdown signal to the PWM. For this purpose, I need to give the comparator ...
I purchased a controller board from HiWonder, who use your STM32 MCU. I asked them if I can use python to program the STM32 but they do not know. Can I use python to program your microcontroller? Do I need to download specific software?
If I want to receive a known number of bytes I can use the library function: HAL_SPI_Receive_DMA()But I would prefer it if when nSS falls to check how many bytes have been transferred and interrogate the DMA buffer.An alternative is to poll, using F...
At startup I do initializations, then go to STOP1 mode. Initializations include setting a wakeup in the RTC and setting the wakeup clock to the MSI clock. The RTC successfully wakes the MCU. In the wakeup callback, I do some things then start a LPTIM...
Hi,i develop 100% of my code in my workshop or office, but sometimes i wish i could do some very light modification to a parameter or baud or something in the field and i dont really fancy carrying my expensive workstation laptop around. So i wonder ...
Hi,I'm having a problem with SPI interface. I am using STM32H753XI Evaluation board. When I issue HAL_SPI_Receive function I get HAL_ERROR due to timeout for receiving data on SPI. What could be the problem?I attached my core dir.Thanks in advance.
Hello,I've been trying to transfer some data from AXI-SRAM to DTCM via MDMA but it seems not functional.The transfer occurs the flag of end of transfer is set yet the data that I have in my DTCM isn't the orignal one contained in the AXI-SRAM.Also im...
Hello,I am facing random HardFaults on a STM32F722. They happen at various places in code, sometimes even during stack's initialization.Stack's analysis do not show any risk of overflow : most of the time, the problem happens while executing main() l...
