I am having issue of ADC and DAC, my ADC section work fine with DMA without Activation of DAC, but when i start to give DAC output it will directly affect to my adc count .i don't know what can i do because i am beginner for STM controller. Controlle...
I am using DMA to acquire eight ADC channels, and would like to get the DMA to de-interleave a capture of 768x8 channels so that in memory: channel 1 data is at address A, A+0, A+1, ... A+767 channel 2 data is at address A+768, A+768 + 1, A+ 768 ...
I have an STM32F401CCU6 with an 25MHz ext. oscillator. I believe the internal RC oscillator is 16MHz. I have tried to configure to use the internal oscillator and as well as the ext. one with no success. Please note that my code _works_ if I don't do...
When using a TIM timebase (rather than systick), the PGSERR bit in the FLASH.SR register gets set after calling HAL_InitTick. Using the debugger, I found that the specific line that causes the flash error is "__HAL_TIM_CLEAR_IT(htim, TIM_IT_CC2)". Th...
I'm using a Portenta H7 from Arduino. It hosts the STM32H747 microprocessor. I was wondering if it is safe to use +5 volts for I2C even though the MPU runs at +3.3 volts? To clarify, on how the Portenta H7 is wired up, I'm using the pins associated w...
I am quiet new to STM32 programming and can't get the external interrupt to work.I started with the NUCLEO-L011K4 and wrote my programm without any issues. I switched to my own board (pdf included) and weren't able to get extrenal interrupts to work....
Hi All,I would like to configure my ADC such that it is able to read from 2 channels. And that the conversion of the channels will be stored in the memory through DMA. But most importantly, I want the conversion to be triggered by a TIMer's rising/fa...
HI,I am using stm32h743 controller and trying to port http webserver application which was working on stm32f7 platform. the application is using socket based apis. here i am generating the code using stm32cubeMX with STM32Cube_FW_H7_V1.9.0 package. A...
I am trying to change from using a Timer PWM controlled outgoing bit stream to an SPI controlled outgoing bit stream. It would be very nice to output a 32-bit word in one shot using the 4-byte FIFO at each TXE interrupt, but the RM seems to indicat...
Hello everyone, I am working on our project based on STM32H757I-EVAL board (or NUCLEO-H755ZI-Q). I have already tested several parts that we expect to use Ethernet, UART, I2C, IOs, LCD, LEDs, etc. I have troubles with LwIP TCP/IP stack and finally I ...
