Hello everyone!That works:int main(void) { ... init_SPI1(); for(;;) SPI1_Send(); }And that doesn't:void TIM2_IRQHandler(void) { SPI1_Send(); TIM2->SR &= ~TIM_SR_UIF; // reset UIF bit in the status register of the timer }Why?Thank you ve...
HelloIs there a book about Cortex M7 like Yiu J. The Definitive Guide to ARM Cortex M3 and Cortex M4 Processors ?
Hello everyone,I’m working with the STM32U5G9J-DK2 and trying to implement a Bootloader + XIP (Execute-In-Place) application architecture using the external flash.Target setup:A minimal bootloader running from internal flashThe main application linke...
I am designing a 4 layer PCB which uses an STM32L433 and working on the layout for the LSE and HSE crystals. I referred to the application note AN2867 for guidance, but I am confused by the isolated ground plane underneath the crystals as shown in Fi...
Hello I'm trying read sector numer 0 from SD card. I use 4-bit mode for sd card reading. My MCU is on Nucleo development board. Card is correctly initialized but when I'm trying read sector I get zeros in buffer and maybe 10 random not-zero bytes. Wh...
Hello, I'm trying read core temperature. I use NUCLEO-U575ZI-Q board. I wrote code: RCC->AHB3ENR |= RCC_AHB3ENR_PWREN; PWR->SVMCR |= PWR_SVMCR_ASV; RCC->AHB2ENR1 |= RCC_AHB2ENR1_ADC12EN; ADC12_COMMON->CCR |= ADC_CCR_VSENSEEN; ADC1->CR ...
Hi,I have been trying to communicate with an SPI peripheral (NOR Flash). I want to use SPI in half duplex mode. The problem is that as soon as enable the SPI peripheral I see SPI constantly sending OxFF over MOSI even though I have not written anythi...
I got STM32U5G9J-DK2 and this Discovery is still assembled with LCD board MB1860A version.But the documentation suggesting this DK have LCD board MB1860B version and share only B version scheme.I taked damage of my LCD board MB1860A and replaced it t...
