Hi can i, if i change the lay-out of my board, replace the original stm32f427VIT6 with a ZIT6 without changing the code?Could get my hands on some ZIT6 instead of the almost unobtainable vit6 for free, but want to know if its possible without changin...
Hi everyoneI'm trying to write the timer interrupt code I wrote in C (pa3 pin blinks at 10 ms intervals) with arm assembly language, but it doesn't work.I don't know exactly how to do the timer interrupt in assembly language.I tried to write my own c...
Dear ST community,I am using ADC to measure different voltages and I need a total of 15 channels and I need to measure ADC in a polling mechanism. When I useHAL_ADC_GetValue(&hadc1);It gives me value for only one ADC channel I am unable to receive va...
As per the below screenshotThe result of regular channel data is to be subtracted with an offset value. But this works only when the regular conversion sequence starts with an odd channel number and offset correction is not happening when the regular...
Hi all,I'm trying to setup a DMA TX UART code using STM32H743VI MCU. The problem I'm facing right now is every time I call HAL_UART_Transmit_DMA function, I get a HAL_DMA_ERROR_TE in my DMA error call-back. The actual line of code is as follows:char ...
The min sample time is 2.5 ADC clock cycles and max.ADC clock is 80MHz, with this the sampling time is coming as 31.25ns but you mentioned as 18.75ns. Here, I think ST has taken the ADC clock cycles are 1.5. I felt it as a bug.
On F4 (and also other families) The TIM2_ETR and TIM2_CH1 are both on the same pins.The pins are PA0, PA5 and PA15.How can I configure the timer/gpio to get ETR on PA5 and CH1 on PA15 ?The alternate function numbers are the same for ETR and CH1...I n...
