i have established communication with a BLDC (Brushless DC) controller. Initially, i send a message to the controller using the function void sendParameter(uint8_t parameter). Following this transmission, the BLDC controller is expected to respond w...
Hi there,I received a new out of the box NUCLEO-144 H723ZG board which I can not connect, but getting the "Can not connect to the target!" message (see below)What I've done so far:- checked the Jumper as described in user manual UM2407 section 5 >> a...
I am trying to set up a multichannel ADC and following YouTube tutorials to create it. However, the STM32 IDE will not allow me to set preemption priority to 1. Similarly, I cannot set the clock prescaler as divided by 2. I need to make a multichann...
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 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...
