I'm making my own low level CAN driver. I have a problem releasing the CANperipheral from sleep mode. So there are more requirements then I found so far. LL_AHB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_CAN1); LL_AHB3_GRP1_ForceReset(LL_APB1_GRP1_P...
Hello ,I am using Standard Peripheral Library with STM32F3VCT6 mcu. I want give delay without using timer of it means want give delay by using RCC clock. Is there any thing by which it can be happen.
I have repeatedly observed that changing the watchdog prescaler on a running watchdog from 16 down to 4 usually causes the watchdog counter to eventually stop decrementing. I assume this happens due to something like decreasing the prescaler value b...
Greeting Everyone,May I have some little help here? I'm currently using STM32F303K8. I had experimented with HAL_UART_Transmit_DMA function within "the main while loop" and the TIM6_DAC1_IRQHandler(void) which was called from TIM6 in Time Base modeMy...
Hi. First of all I want to thank you for giving time to this post. When i create bare metal program for blinking an LED don't work. The LED don't blink but when i enter DEBUG Mode with KEIL uVision the bit 0 in ODR resgister for GPIOC toggle every 1 ...
Hi, I is developing a BLE appilication using X-NUCLEO-IDB05A1 module. I use FlashUpdaterTool (Version 2.1.0) to connent my NUCLEO board of L476RG (VirtualCOMPort Application V0.0.1 ), which connect X-NUCLEO-IDB05A1 module. During updating the fire...
Hi,I am using stm32f779 RTC upto subseconds granularity that is using SSR register value for giving upto milliseconds level of time output .The scenario is such that there is external time source ( network clock) to which I synchronise RTC by updat...
Hello,I have written these codes for transmitting an array to USART.1)The Message[21] Array fills up every 200us. It sets Flag=1 when data is ready.2) If the user makes the PB11 pin low it starts DMA section to transmit the data.(All data will transm...
I can't seem to find this in the datasheet or reference manual. The GPIO OSPEED register is documented as 00: Low speed, 01: Medium speed, 10: High speed, 11: Very high speed. But what are the actual frequencies? I can't seem to locate the informatio...
Hellofor my application I use STM32L0, and I want to retrieve the exact date without changing it every time I turn off the power. Is there a timer that was triggered on the production day of the STM MCU that will allow us to retrieve the date?
