Hello everyone!I am trying to write to flash without using built-in HAL functions. Initially, I want "Hello World!". The Flash is only aligned double word writable as shown in the reference manual (RM0394) standard Programming technique Section 3.3.7...
Hello,I have NUCLEO-STM32F429ZI kit and I want to operate the SPI as max speed. So, I design one simple example like make SPI1 as Slave and SPI4 as a master mode.This is worked for SPI_BAUDRATEPRESCALER_8 (11.25 MHz), SPI_BAUDRATEPRESCALER_16 (5.625 ...
I have a custom board design using a STM32F407. Timer6 is running in interrupt mode with a 42 usec period. I also have Timer7 running in interrupt mode with a 3 second period (upcount mode).Each time the Timer6 interrupt runs I reset the Timer7 TIM...
I'm struggling to find a solution to this by searching.I have an existing system running using PA1 as an EXTI set up through Cube MX. I just need to add an exrernal interrupt to PA0As far as I can see the following code is all I should need to add...
Hi,I try to send data via CAN from the nucleo board to a USB-to-CAN device (peakCAN).I configured PA12 and PA11 as FDCAN1_TX and FDCAN1_RX. I measured pin 12 and pin 14 on the CN10 connector with a salea logic device, but got no valid frame. Pin 12 ...
My setup is I have timer 15 triggering ADC1 at a fixed frequency - say 1MHzI have 4x over sample ratio set and the single trigger for all over sampled conversions set so I only get 1 DMA transfer for per 4 samples.So with 4x over sample and 1MHz tri...
1st question: How many numbers will be saved in RAM?2nd question: Is it possible to get more accurate data by decreasing the ADC sampling rate.Thank you.P.S: I'm sorry, if this is a very simple question but I am a structural engineer and nobody is pe...
Hi, I have a problem configuring ADC1 on an STM32F429 to do a regular scan of a sequence of 4 channels without using DMA. The fourth channel is the internal temperature sensor. The third channel to be scanned always gives an overrun error (ADC_SR.OVR...
For SD memory card when there are errors in data transfer or do multiple block transfer, we need use CMD12 to abort the transfer, And there is function for SD card in HAL library, for example, there is 'SDMMC_CmdStopTransfer' in STM32H7's lib. But ho...
Hello,How do I retain a RAM section from bearing filled with '0' between resets.Suppose I have a pointer to 256 bytes buffer that I'd like to preserve between resets (as long as the power was not disconnected), could you please guide me, step by ste...
