Resolved! Why are the timer bus and timer clock different? (F446RE)
HelloI'm using timers with DMA and I was asking myself of the use of having different clocks for timer clock and timer bus. For example timer 2 has a 90 MHz clock and a 45 Mhz bus. What would be the limitations of the bus?
Resolved! STM32F446RE TTCAN level 1 possible?
Hi everyone,I think like most people, I ignored the errata sheet till it was too late. I know that the stm32f4 and quite a few others do not provide hardware support for TTCAN, which as far as my understanding goes is level 2 CAN (global time synchro...
FDCAN Receive data issue in STM32G0B1RE
Hello Every One!! I am Using NUCLEO G0B1RE Board, facing Issue with CAN Receive Function I am using MICROCHIP CAN BUS ANALYSER and NUCLEO BOARD for CAN Communication void CAN_Recieve(void){ while( (HAL_FDCAN_GetRxFifoFillLevel(&hfdcan1,FDCAN_RX_FIFO0...
I'd like to know to set the TIMx_CCRy? register, I've configured the
I've synchronized TIM3 and TIM4, the TIM4 being triggered when the TIM3 Output Compare No Output on channel 2 is active. I've configured the TIM3 channel 2 as "Output Compare No Output"In order to control the time delay between TIM3 and TIM4 activ...
Read From SD Card gets stuck in a While-Loop (Bug?)
I am working on a custom board equipped with an STM32H753 and a SD-Card connected via SDMMC 4bit wide Bus. FreeRTOS is used. HAL is generated using CubeMX and the package "STM32Cube FW_H7 V1.9.1".CubeMX generates the file sd_diskio.c and in it (line ...
The equation for actual code of internal ADC in SAM4S series of MCUs
I need a clarification regarding the actual ADC code equation for SAM4S family of microcontrollers. The equation from data sheet is,Does this equation hold good for both single ended and differential inputs ?Looks like it is considering a differentia...
How to configure ADC after wake up from STOP (low power mode)
I am using LPTIM for periodic ADC reading (every ~250ms) and periodic IWDG refresh. CPU should go to Stop mode when the ADC value is under certain value. If the ADC value is over certain value then CPU should reset end continue in Run mode. ADC is cl...
Strange ADC behavior
I am working in a project where I have to sample a signal with a sampling frequency of 8 kHz with the ADC. That data is send from the ADC to SRAM using DMA and then send through UART interface. I am using a "Blue pill" board (STM32F103C8T6) with a sy...
