Dear ST Community membersI am currently designing a PCB and utilizing the STM32G473VET6 MCU. I have noticed that there are several unused pins. Should I leave these pins unconnected or is there a recommended course of action for dealing with them?tha...
I am currently developing the firmware for a project. I have two boards, running identical firmware but the operating temperature between the MCUs on the boards has about a 10°C difference, 43°C vs 53°C (confirmed with a thermal camera).We have more...
I working on motor control application with stm32g484ret6.Timer1 generates 3 PWM lines with complementary lines (with some deadtime) in center aligned mI have ADC readings to sample the phases current.Timer1 output trigger TRG0 is defined as update e...
Hi all,I am trying to configure burst dma on my board (stm32g474). I have successfully configure the dma for single register, however, when I want to configure dma for more than one register, I failed to do that as it only allow me to fill one addres...
Hello,I'm currently using the HRTimer (on a STM32G474) for duplicating a input PWM signal. That means that in my case, I have one PWM input coming on 2 events (1 for the rising edge, 1 for the falling edge) and the outputs of the HRTimer B, will be s...
I have a couple dozen of custom boards with STM32G4s on them. These boards are all 'identical' and the software being loaded on them is the same. BOOT0 pin is currently floating so on my initial load I held it to ground and changed the option bytes v...
I am about to release firmware to production and would like to include the proper options bits in the firmware so that production can simply program the .elf file at the same time as updating the option bits. I realize that there are several option ...
Hi Can anyone help me understand the difference betweena) writing control loop and obtaining ADC values in HAL_ADC_ConvCpltCallback with ADC ISRsinstead ofb) writing control loop and obtaining ADC values in HAL_TIM_PeriodElapsedCallback using TIMER I...
HelloIn STM32G474RET6 I want to have 2 banks. Bank 1 for golden (boot image) and Bank 2 for an application image.As I want to have a robust solution I always want to boot from Bank 1 (address: 0x8000000), to check if valid firmware exist in Bank 2 (a...
I'm trying to use USART1 for Async however I cannot send data to the board. I'm using an FTDI USB-UART converter cable to test, the Nucleo is sending correct data my PC data no problem.I can prove my code and terminal program on the PC works 2 way wi...
