Hey. I am trying to read multiple ADC channels using DMA but with no luck. My project settings:I have selected 4 channels and enabled Continuous conversion mode as well as DMA Continuous requests. I have also created a circular DMA for ADC : #include...
Hello,At work we have developed firmware on a stm32l0 based on different time base with systick and counters of elapsed time (10ms, 100ms and 1s). Therefore, some function are executed periodically.The board is powered with 3.3V.In order to measure c...
I am using below commponet MCU: STM32H7B3IIT6SDRAM: IS45S16800F-7CTLA1-TR FLASH: MX25LM51245GMI00I am revising the card design according to high speed signals. But how do I calculate the length of the paths to be drawn for SDRAM and FLASH?How many m...
Hi, I'm trying to read ADC data with 2us periods using ADC interrupts on Nucleo F334R8. I'm triggering ADC with TRGO event of Timer 2. I'm toggling a pin whenever callback function is called to debug using an oscilloscope. However, I cannot observe 2...
Hello ST community! We're using STM32F401RDT6.We use the RTC to maintain scheduled events that occur in the time we set, but not with the RTC's Alarm mechanism, rather our custom-made mechanism based on the current epoch time which is being updated e...
Hello, This has been asked many times but still can't find easy solution...I followed this tutorial : https://www.youtube.com/watch?v=ly3_JEC_d9w&ab_channel=ControllersTechbut still have some random failure ;(Also looked at https://github.com/STMicro...
Hello, I'm using an stm32f429zit6's ADC in triple interleaved DMA mode. They're giving me 7.2 Msps currently.The ADC is continuously running in circular mode and filling a buffer with a size of 3000.So I wanted to find out the DMA buffer pointer when...
