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...
Hi!How to set Gpio pin high while MCU is in deep sleep mode to keep power supply on?I cant find any information.
hi guys, i work on STM32 L4R5ZI without HAL functions.I use DMA for LPUART(for HMI) and SPI (for component) and I want synchronize these communication with DMAMUX. I see in the reference manual, some synchronization signals (EXTI, dmamux_evt,…), I wo...
Anyone know of any alternative hardware solution(s) from other manufacturers that is equivalent or providing similar protection features as the STSAFA100DFSPL02? Namely STSAFE.Thanks.Ref to STSAFA100DFSPL02: https://estore.st.com/en/stsafa100dfspl02-...
Hello Dear Engineers and Developers,This one is an advance question for me, perhaps as easy as ABC for you.I want to put image data on the external ram. Either of Keil or Stm32cubeIDE compilers are acceptable. I know that I should change the linker s...
