We have implemented a total of five push buttons—two connected to Port E and three connected to Port M. The GPIOs of Port E are functioning correctly. However, the GPIOs of the push buttons on Port M are not being detected properly by the MCU.Even wh...
Hello,I am writing & erasing flash during operation, and this seems to cause a bus stall which prohibits all execution from flash during these operations.AN4808 seems to indicate that if you use a dual-bank device you can avoid this by executing out ...
Hello,I’m trying to setup the PSSI interface on the STM32H523RETx to transmit data. I cannot find how is the PSSI_PDCK configure. Neither in the clock tree nor in the RCC register the PSSI clock can be configured (except for enabling it). In RM0481 t...
Hello everyone In my application using an STM32H7, I noticed that the VBAT pin, with VDD off, draws 1.9 mA. This is excessive current draw.I'm using a CR2032 battery in series with a 100R battery connected to the microcontroller's VBAT pin.What could...
I'm currently using single 16-bit ADC, my requirement is to have ADC conversion error less than 1mV.I'm using the ADC with DMA. I'm a beginner, currently getting 1-2mV error and it is not constant too. #define SCALE (3300.0f/65535.0f) uint16_t adc_...
Hi~ NUCLEO H563ZI USART GPDMA channel6 not received buffer. static void MX_USART6_UART_Init(void) /* GPDMA2_REQUEST_USART6_RX Init */ NodeConfig.DestAllocatedPort = LL_DMA_DEST_ALLOCATED_PORT1; NodeConfig.DestHWordExchange = LL_DMA_DEST_HALFWO...
Greetings,I have used CRC peripheral in STM32G0B1 and its working fine. I am using this peripheral to calculate 16-bit crc. How to accomplish same task in STM32F207ZG ? I am using HAL and after code generation crc init code is very incomplete as per ...
Hi everyone,I am working on an STM32H523 MCU and I have recently observed some strange behavior regarding the PB14 and PC9 pins. I have the following setup:PB14 is configured as input (I use this for the TIM2_CH2 alternate function, but this does no...
I am using LTDC for interfacing with a TFT LCD. The LCD is connected with 18 bit (RGB666) interface. I have selected the pixel format as RGB565, and I am using a frame buffer stored in the internal SRAM. The frame buffer has been populated with 16 bi...
Hi folks, I'm using one timer to generate a pulse train (TIM4), and a second slave timer to count the pulses (TIM8). This is on an STM32U575.I have this working nicely using a timer with centre aligned mode 3 for the counter mode, with the channel u...
