STM32H7, MDMA IRQ double hit... and working only with debugger attached.
Hello,I configured the following ADC flow:ADC3 => DMA2 => SRAM => MDMA => DTCMEverything was working well using the MDMA in single buffer transfer mode. In each MDMA interrupt I was reconfiguring the MDMA channel to get ready for the next DMA2 transf...
Does the STM32CubeIDE have a truncate function?
I am working with a Nucleo-L476RG board, and I am writing a program that generates HMAC-SHA-256 values. I want to truncate the output of the generated HMAC value to only output n amount of bits. For example, if my generated HMAC value is 80 bits, I w...
Resolved! STM32F7 Memory map in AN4839
We have a question about the memory map in section 3.1 of AN4839. The note states that "by default the MPU is disabled and that in this case the memory map is defined as the default address map".Immediately under this statement is a table with a memo...
How to wait for Interruption to continue code execution ? Or better non CPU blocking solution for my code.
Hey,I'm basicly filling a tank with liquid and I have 2 level sensors in this tank. These level sensors are connected to GPIO_EXTI of my MCU so when the water reached the sensor level, an interrupt occure. If the tank is filling or emptying, I must d...
STM32L4 ADC oversampling - What is the total sampling time ?
I using STM32L4 ADC in my project to sample analog acceleration data. The ADC conversion is triggered by 10kHz timer by which i was able to achieve 10kHz sampling rate using DMA. Now, i wanted to implement oversampling by a factor of 2. Now what is m...
Resolved! Is there any way to know when a STM32H7 SPI master has completely finished sending data, in endless-transaction mode?
When transmitting in endless-transaction mode with the STM32H7 SPI periph. (that is, setting TSIZE = 0), how can I know when the master has finished transmitting all data? Not only that its Tx FIFO is empty (which could be done with TXP) but also tha...
Debug message "Failed to assign value 8000f4d, to register 0" with STM32L432KC and CubeIDE
Hi,Since a few minutes, I'm experiencing a problem in CubeIDE v1.10.1 when I try to debug my code. Here is the message I'm getting in the console window:File download complete Time elapsed during download operation: 00:00:00.818 Verifying ... Dow...
Determination of the reason for wake up following shut down on STM32L471RGT6
Hi,I have the following code to enter shutdown with UART interrupts for the wake up. The processor does shutdown briefly (confirmed with power measurements) and then wakes up after ~.5 seconds. I cannot see any traffic on the serial ports and I can't...
Resolved! 2 memories
I have 2 memories with not the same type the first is hyperram and the second is nor flash and it is mandatory for my project to use both of them.i am not sure how to do so or if is it possible to use one on the st board and link the other one separa...
