STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello,I've ordered two NUCLEO-H745ZI-Q at a same distributor, on a same time.It seems that one CPU's board is "bricked" : The software runs fine on a board. the same software literally doesn't run on the second board.The embedded debugger tells that ...
Hello,I have tried to implement a simple SPI driver. Only with LL Lib. I would like to use DMA and I will do it without interrupts.So it works now. But for me it is not clear how to poll if the transfer is finish in the right way.So I use rx and tx d...
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 have a project which needs to store the state of the program on an eeprom.Unfortunately there is no built in eeprom on stm32f7508-dk board.I have bought M24LR64 chip for i2c eeprom.Unfortunately the program get crashed on read operation (only when ...
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...
