Hello,I have developed my own board using the STM32H723VG and two equal sensors connected separately via SPI1 and SPI2.I have underclocked the MCU to 300MHz. The SPI clock is 48MHz while the communication frequency for both sensors is 24MHz. As CS I ...
I need to use the energy collection mode of ST25 to wake up L4. The software used now is En.X-Cub-NFC7. How can I modify the example code to set L4 to low power mode and wake up L4 only through the energy of ST25?
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...
Hi,I am using LPUART and LPDMA on STM32U575. But I am getting Data Transfer Error.I have tried LPUART with GPDMA it works fine but LPUART with LPDMA giving Data Transfer Error.So I have two questions:1. Can we use LPUART & LPDMA together?2. What will...
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...
