STM32H7 ADCs with DMA when D-Cache enabled
Dear all,I am trying to configure ADC1, ADC2 (ADC1 and ADC2 in multimode) and ADC3 running simultaneously with DMA.I have a running code for STM32F7 series and I assumed that I could use DMA in the same manner but DMA cannot store data taken from ADC...
First time programming a stm 32 - key matrix
Hello all!I'm in the process of designing my first full custom sim racing steering wheel. I have designed and ordered a pcb with a stm32f103cbt6 mcu. The pcb works good (so far) and i have it connected to my pc via a swd clone st link debugger. I am ...
In STM32U5, What is the right Oversampling Ratio for ADC1 14bit to achieve 16 bit. Is there a formula?
following is observation with different OR
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...
