Hello, i am using stm32h723zg nucleo board in my project. my system clock frequency 480 MHZ, that means it does an instruction for about 2,08 ns as well but the time i measure9-10 ns , That's too much.(application ; Writing adc value to another v...
Im trying to put STM32H743 in stop mode with wakeup from external interrupt. So far core wakes up immediately afterHAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFE);EXTI_CPUPRx registers all set to 0, so what wakes up the CPU? Is the...
Hello, I need to perform some task without using HAL libraries. I am using CMSIS. To start, I have set up a blinking led with timer. I programmed the clock as per attached picture. The source clock of TIM6 should be 60 MHz but the led behaves as it w...
I have done an SPI transfer only with DMA and working fine, but when I need to do a daisy chain configuration its not working. I am suspecting the NSS signal.below is SPI configuration#define SPIx_Mode SPI_MODE_MASTER #define SPIx_Direc...
I know that IDB05A1 is NRD(Not recommended for use) but still i want to use IDB05A1 in low power mode with L073RZ MCU can anyone guide me.
I am working on STM32H743VIT6 and using LAN8742 as phy. i generated the project using stmcube using repository stm32h7 1.5.0 . I used the same mpu and system clock configuration as in the ST examples. When I switched on the supply to mcu, the ping d...
Read out protection issue ,I am unable to reprogram the board and the previous code is not executing as well. I have faced this issue in multiple boards .I am unable to debug this issue since long and the last option is to replace mcu with new one. A...
I am trying to get a simple I2C connection running and the I2C1 peripheral on a STM32L052 is giving me hell. Here is what I have done so far:I have written a simple driver for STM32L053 using I2C2 with interrupts. I have tried it on a couple of diffe...
Actually the RTC alarm I've set isn't coming out exactly. It triggers only once, after that it'll keep getting triggered for every one minute. How to do it for every X minutes?
With STm32F429ZIT6 the RTC battery used is 3.6V Ni-Cd and the RTC crystal used is 32.768khz. Initially, it works well for some days but after 1-2 months RTC date and time get reset to default value every time system is power reset. Need help to resol...
