USART1 behaved abnormal
hello allI established a virtual com port using a 4G modem, connected it with my F413ZH USART1.I used a DMA channel for RX. set HAL_UART_Receive_DMA(&huart1, (uint8_t *)&RxS0, 1);I could get datas from it at first. DMA2_Stream0_IRQHandler() will be c...
STM32F7 ADC Sampling Calculation
Hello, I'm using ADC with DMA of STM32F7 MCU. I want to calculate the ADC Sampling Rate. Is there a formula that I can use ? With 12Bit resolution, Is it possible to reach 2.4MSPS ? I'm using CubeMX for code generation.
STM32H753 208 pins, can read from SRAM but can not write to SRAM. The SRAM is Panasonic IC
aTxBuffer[0]=0x11; HAL_SRAM_Write_32b(&hsram1, (uint32_t *)ADDR_MNM1221+0x0, (uint32_t *)aTxBuffer,1); It is a write code to SRAM but fail. The Panasonic IC MNM1221. The attachment is the datasheet.This reading code is successful. HAL_SRAM_Read_32b...
Where can I download example for STM32L152C-Discovery with touch sensing?
Hi,I'm using STM32L152C- Discovery board and I would like to use th touch sensoes pad, please advice from where I can download example code for STM32L152C-Discovery with touch sensing
ADC accuracy better in F0 (Nucleo-F030R8) than in F3 (STM32F3DISCOVERY)?
Hi all,I am doing some testing with the ADCs of an STM32F0 and an STM32F3 using 2 development boards: Nucleo-F030R8 and STM32F3DISCOVERY. I am finding the accuracy of the measurements is much better on the F0 (<0.1% FS) than on the F3 (up to 1% FS).T...
STM32L052K8U + DS3232M I2C not respond
Hi, everybody. I have a problem, can not connect via I2C with RTC. Use a microcontroller and RTC STM32L052K8U DS3232M. Used library HAL. From the watch constantly comes NACK. The wizard sends the correct address (I'm sure of that, but just in case I ...
STM32F4 USART DMA RECEIVE
Hello everyone.I'm just starting stm32f4. I'm try to use USART DMA, with Transmit it's ok. But with Receive, when I send characters from Terminal to Board first, for example 'aaa', it's ok. But the second characters I send, for example 'bbb', so the ...
How to stop flicker on STM32F769 disco board
Hello!I'm looking for info about how to write a flicker free program on STM32769 disco board.There are a few samples in the latest firmware (stored in repository / STM32Cube FV 1.21...).I tried all the samples for DSI, in cmd mode or video mode, all ...
hard fault after configure systick
i use NUCLEO - F767ZI and test a simple code as followint sum(int a,int b){ return a+b; } int main(void){ int dly; __enable_irq(); SysTick_Config(100000); NVIC_EnableIRQ(SysTick_IRQn); dly = sum(1,3); return 0...
