Ambiguous data over MISO Line SPI Communication (Master mode).
Hi all,I am using STM32F334 for SPI communication with a TDC7201 chip from TI.I am using the Low-Level Drivers to initialize the driver and communicate. Here is my initialisation routine: __HAL_RCC_SPI1_CLK_ENABLE(); LL_SPI_InitTypeDef SPI1I...
Resolved! Sending USART message via interrupt using registers
Hello,I am working on a college project and struggle with sending a message to the virtual terminal using USART interrupt.I work with following code:void UART_Send (uint8_t *buffer){ USART1->CR1 |= USART_CR1_TXEIE; // Enable TXE Interrupt USART1-...
Resolved! No timer interrrupt after switch to user application
STM32G473VC, custom board.I use an own bootloader which resides at address 0x00000000 , the user application resides at 0x00008000. I did set external files correct to use the bootloader in user applicationsystem_stm32g4xx.c : #define VECT_TAB_OFFSET...
Hello, I am trying to measure the power consumption of the STM32U575ZI microcontroller on the Nucleo-144 board but the results are much higher than expected.
I am using an ammeter connected instead of the JP5 jumper, as indicated in the manual (UM2861) and tried several examples.For example: in PWR_EnterStopMode example I see around 568uA on the ammeter.From the datasheet I expected to measure around 100...
Resolved! Set software interrupt with its own priority?
MCU STM32F765GZMy Problem:EXTI_LINE_0-4 has separate IRQ handlers but al are occupied.EXTI_LINE_5-9 share the same IRQhandler and also priority. pin 6 is needed with prio 1(brownout mon)EXTI_LINE_10-15 share the same IRQhandler and also priority. pin...
Resolved! CAN bus apply filter on extended ID only (discard standard ID)
Hi,I'm using extended ID for my CAN bus. I want to filter ID 0x12.My code is working well when I receive an extended ID frame with containing the ID 0x12. If the received ID is something else than 0x12, the FIFO callback isn't triggered.CAN_FilterTyp...
Two leds based on one interrupt line
Dear sir,I am using STM32F769NI microcontroller. I want to glow to different Leds on one external interrupt line i.e. Led1 on rising edge and Led2 on falling edge. Can you please suggest me the solution.Regards,Manoj
