Hey Folks.So, I have the H757I-Eval Board that I got as a gift, and given that I'd like to try some stuff and even follow some tutorials, I miss the exposition of the PINs. Reading TN1238 which talks about a fan-out expansion board, it says "The prin...
I am making this call: if(HAL_SPI_Receive_DMA(&hspi3, &aRecvBuffer[0],3)!= HAL_OK)inside an external GPIO interrupt handler that gets called every 20 us. It is used to read data from an external ADC. I noticed that this dma transfer works well only ...
I'm trying to follow the OSPI_NOR_MemoryMapped STM32CubeIDE example, but for a different device (W25Q128FV). Write Enable, Read Status, and Erase Sector commands behave as expected, as well as memory-mapped reads. This has been confirmed by monitorin...
Code isn't complex, hence i don't understand what could be the problem.char pin_status;pin_status=HAL_GPIO_ReadPin(SENSOR_H1_GPIO_Port,SENSOR_H1_Pin);
Usually peripherial SPI drivers support 3 delays to control signals timing:Delay from SS enable edge to first SCK edge (SS Idleness) - supported in STM32H7xxDelay between data (Inter-data Idleness)- supported in STM32H7xxDelay after SCK edge to SS d...
Hello,I am trying to copy the content of a float variable with memcpy into uint32_t variable. unfortunately the binary content changes after copying. it should be 0xfff00000, like in the float variable. Does anyone know why this happens and how can I...
Hi!I have a problem setting up Serial Wire Output over ITM. I followed every tutorial on the Internet (including this forum) and I still haven't made any progress. I run the MCU on 280 Mhz: In Pinout & Configuration -> DEBUG I configured Serial Wire ...
I am trying to do RTC wakeup interrupt using STM32L412RBT6 microcomtroller in baremetal c, but the interrupt is not firing, below mentioning my code.int main(void){ LedConfig(); Tim6Config(); RTC_ClockConfig(); RTC_Init(); /* Loop forever */ while(1...
