Hello,I am trying to transmit data to DAC using SPI DMA method on STM32h745 I tried all the methods that mentioned on forum. But i did not get the data on MOSI pin, when I use the polling method the data is successfully transmit .const uint16_t addr[...
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...
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 ...
following is observation with different OR
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...
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...
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...
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...
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...
