Hi all, i am trying to use MDMA to transfer data from a cyclic ADC-DMA buffermy ADC buffer is of x size and it is cyclic: adc_buffer[x]and i want to transfer its data via MDMA to a larger buffer while its samplingmeaning that after every ADC iteratio...

Hi Everyone, in my previous posts i pretty much beat the bush around this subject and i did get some good supportbut i keep getting stuck with this issue.im using STM32H743ZI2 Evaluation board set to 32Mhzthe ADC is 16 bits and running on "fast chann...

Hi all, im using Cube IDE STM32H743ZI2 Evaluation boardim curently sampling ADC2 and storing the output at an internal array using DMAthe array size is uint16_t[100,000]my requirements as to store much more data which means i have to use a diffrent m...

Hi all i'm implementing a serial communication between my evaluation board and my PCi managed to send data from my board and read it via PuTTY.but when i run HAL_UART_Receive_IT and send messages via PuTTY it doesnt trigger the "HAL_UART_RxCpltCallba...

Hi all, i'm experimenting using ADC in STM32H743ZI2i managed to get the single channels working on ADC1 and ADC2,and i want to use ADC3 with multiple channels, oncourse i followed all the manuals in youtube etc.. but still no lucki am using ADC3 cha...

Hi thank you for clearing things up.i didn't really find anything about "double buffer mode" but it sounds like that would be the solution for my casealso i just now realized that i wasn't able to use the ADC at it's full sampling speed because of th...

Ok, i do only need to record once and store the data so that my mcu can proccess the data once it's free.and i was certain that this MCU can do that seeing it is able to sample and such a high rate (up to 3.6Mhz)i may pursue the solution of an extern...

to my surprise this was actually the problem, the RX pin i was assigned by default for some reason did not work.when i changed RX Pin from PB11 to PD9 (my TX is PD8), everything seems to work.im still not sure why because PB11 wasn't used in my code ...

yea i did try the blocking one but didnt manage to get it working either, i tried a diffrent terminal as wellthese were my steps for "HAL_UART_Receive" (no interrupt)i keep getting timeout* disabled USART3 Interruptcode:int main(void){ uint8_t rx...
