i am using the STM32L4 Nucleo board L4R5ZI .i am trying to configure i2c to read time from the RTC DS3231.but i am getting only data as zero.what may be the issue.i have attached the code.kindly help..
i am working on enabling the gpio interrupt..i have setted a GPio pin as a interrupt and i have given priority for the interrupt and configured as a rising edge and written callback for that..but the issue when i apply high on the GPIO the interrupt ...
I am trying to do a partial integration on a 550 KHz waveform using STM32F4 Discovery board using the Waijung toolset in Simulink. The sampling time that I am using is 0.018 us, i.e 3 cycles if the clock frequency is 168 MHz. The ADC prescaler is 2, ...
I would like to know if there is any examples on SD cards with SPI interface and HAL drivers. I use cube MX to generate my code and also the HAL librarys. However i know to get SD cards working with SPI I need to change the low level files which fatf...
I'm having problems to read my current sensor, which is located at the source leg of a power transistor. I'm using the sensor TLI4970This is my routine every 10ms:HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_RESET); //Bring slave select low HAL_SP...
I have a UART configured in DMA read mode:/* task 1 code*/ uint8_t dmaRXBuffer[1]; HAL_UART_Receive_DMA(&UART_DOWN_USB_TO_SERIAL, dmaRXBuffer, 1); /* UART DMA receive complete ISR code*/ void HAL_UART_RxCpltCallback(UART_HandleTypeDef* huart) { if...
I have a STM32F756 on my PCB. The microcontroller was responding with no problems, has been programmed and software running on it. It was put to the side for a few days, and when picked up again, the micro has become unresponsive and the SEGGER JLink...
I am using an STM32L476VG which does not have UART transmit/receive fifo's.Therefor I am using DMA for periodic transmission of some data (3 bytes at 125kbit at about 2kHz).This is all configured in CubeMX and functioning (DMA in normal mode btw).I a...
