Hello,I have here two Nucleos with an H743 on it. If it is rev Y, it is the "old" 144pin Nucleo board with the break-off ST-link board on top. For this there is a schematics in appendix A of the user manual. But if it is rev V, it is NUCLEO-H743ZI2 ,...
Hi,I have an external SPI 8 channel ADC which is connected to the STM32,one of timers would generate a 32KHz 50% pwm signal which is connected to the ADC convert pin, the ADC has a busy pin which is connected to the EXTI0 of the MCU.The plan is to us...
Hi I'm trying to debug a Windows C application that was written using Atollic. It uses the gdb debugger.The program has some options that have to be parsed into the program. I have entered the options into the "Arguments" tab in the run/debug configu...
Hi STM32-Community, I'm using an STM32H743 with ADC3 in circular DMA mode. ADC has a clockfrequency of 48 MHz. I'm using 8 channels within this ADC3 and also configured the DMA with said channels each with a sampling time of 64.5 cyles. I'm using an ...
Hi, I am using STM32L072CZT6 for my project. The device operates in two stages: It wakes up at scheduled intervals, save the number of interrupts received to flash , and returns to standby mode. During standby, interrupts wake the device, the count i...
Hello.I'm trying to use STM32 U5A5' SRAM (SRAM1,2,3,5) and I'm encountering some very weird behavior.When I use the entire aforementioned sram blocks, my mcu hard faults.uint8_t __attribute__((section(".TEST_Section"))) data[1024*1024*2];int main(voi...
Heyho,about VCAP / LDO connection in STM32H7 series without SMPS, for example in STM32H733ZGT6 (LQFP-144), when using the internal LDO for core supply.As far as I understand, the VCAP pins are for the connecting buffering capacitors to the internal L...
i have an issue with my timer interrupt that every 500 us happends and external interrupts (12EXTI) .when the timer interrupt happend , the external interrupts never execute.i dont know why this is happening.i mean it supposed to pending for other in...
Hi,Im using STM32L031F6P6 mcu for one of my project. Im also using IIS2MDCTR & LSM6DSV16BTR sensor.I need to find heading regarding that i have few doubts.1.Will STM32L031F6 mcu support mems1 package?if no could you suggest a mcu which support the sa...
USING MCU - STM32H743XIH6As per datasheet "STM32H743XIH6_Datasheet" page 139 it is mentioned that GPIO can sink/source 8 or 20 mA.When MCU will be going to source 8 mA and when it will source 20 mA?Is there any current control configuration inside MC...
