hello,I have question about adc on stm32.If Vref is connected to Vdd, VddA is slightly smaller than Vdd, ADC might be inaccurate?I just became to konw that our hw-engineer did mistook on connections on stm32.( I found that 1.he connected vdd and vref...
Hello everyone,I'm having some trouble using the ADC in the STM32U585. I developed my own PCB where the MCU's VDD and VDDA are connected to 1.8V. I need to measure about ten analog signals. I have two main problems. First:VREF+ = VDDA = VDD = 1.8V. W...
Hi,I wanted to code an application where the external interrupt would stop the motor. I am gonna be using two limit switches - one with rising edge trigger and one with falling edge trigger.Unfortunately, none seem to work. Please help.I have attache...
HelloThe Flash (MT25QL256ABA) is connectd to the STM32H743ZI (Nucleo) via SPI_3 and DMA. Send and Receive buffer are part of the SRAM3 area. There is no cache enabled.To erase the flash the following procedure is done:Send Write Enable Command (HAL_S...
I needed help getting started with Stm32 L496 processor interface with IS29GL064 nor flash mem. It's my first time interfacing with any external memory. I have decided to use FMC controller to drive this flash mem. But unaware of how to setup the co...
Hi, I am using cubeMx generate the STM32F302VE project, which for receiving the usart1 date by DMA circual mode.My config as below:enable DMA, but disable DMA interrupt;enable USART1, and enable UART_IT_IDLE;Now, the project can enter the "USART1_IRQ...
Enabling any interrupt at the initialization triggers the WWDG_IRQHandler when watchdog timer doesn't even configured in the code whereas excluding bootloader fw doesn't seem to cause any issues, code runs fine. In the bootloader fw, I haven't config...
I am using the NUCLEO-C031C6 dev board and I seem to be having many difficulties. I am trying to do a printf() or use a sprintf() method to print a float number to the serial port. I noticed that this controller device(STM32C031C6T6) does not have a...
Dear ST community Hello,I want to use the gyro-meter on the the STM32F discovery board and communicate on SPI,I am using the default configuration with cubeIDE and I have a question in Cude Mx graphical interface.After generating the code using Cube ...
