I use NUCLEO-H7S3L8 to evaluate our new solution. I want to use GPIO port P to control a few external components.I add some test code into NUCLEO-H7S3L8\Examples\GPIO\GPIO_IOTggle project, like the below snapped code:__HAL_RCC_GPIOP_CLK_ENABLE(); GPI...
I am experimenting with a STM32G431 dev board (breadboard friendly) but eventually the project will use a STM32H723 mcu.I am generating PWM and PWMN signals with dead time using timer 15. I need to generate additional signals based on these two and ...
Hello team,Good day,I am having USB Disconnect Issue with my custom board based on STM32F303 Device, configured as USB HID in Firmware with Full speed. Schematics attached here with.It is Self-Powered board and no VBUS Detection implemented, Currentl...
When working with the DCMIPP Pipe0, what configuration must be done in order to receive a frame? I've followed similar steps as to the provided examples in the N6 1.2.0 repository: DCMIPP init -> sensor probe -> pipe start. I've verified my sensor is...
I have my internal Vref set to 2.5V (stage 0). The value reads correct (2.52V) with a meter on the test point below until I call HAL_ADC_Start_DMA(). Once HAL_ADC_Start_DMA() -> ADC_Enable() -> LL_ADC_Enable() is called the voltage goes up to arou...
Hi,Still attempting to work with STM32F767ZI board to generate signals to manage I2S mic (INMP441)I have followed many recommendations, even used MX, but still no clock nor word select signals are generated from MCU....But throu GPIO I can generate a...
Hi everyone,I'm working with the STM32F405RGT6 and its CAN peripheral. I have a couple of questions regarding CRC handling:Does the STM32 CAN peripheral automatically calculate the CRC for both sent and received CAN messages?I noticed there is a CRC ...
I am just getting started with the stm32h723 ADC. If I create a regular sequence group of several input channels, how does my ISR know which channel was sampled last (which channel's data is in the DR)? I don't see this in the registers.Thanks,Ma...
I am measuring time time it takes to do ADC conversions on an STM32H753ZI Nucleo board, using the function function HAL_ADC_Start_DMA(). This converts 6 channels of ADC3, using 16 bits, with DMA. The one function call handles everything including D...
I’m working on a program to transmit data over SPI1 and SPI2 using DMA. For output I only use each peripheral’s CLK and MOSI lines. SPI1 and SPI2 differ only in the exact data being sent—their configurations and the number of bytes are identical. Als...
