The name. Basically using RTC interrupts to run the call back function every minute and increment a minute counter to do stuff with. However sometimes the minute double fires. There was a post regarding TIM2 firing twice and I tried to clear RTC flag...
I called the "HAL_UART_Receive" function in my "at_send_cmd" function and set its timeout parameter to 30 seconds, but I observed that the function immediately returned HAL_TIMEOUT.My SysTick should be working properly, and I can use the HAL_Delay fu...
Hi all,I am working on stm32f103c8t6 controller.I am using LSI Clock of 40MHZ & external clock of 36MHZ.I am trying to read the clock after power off &n on by using the following code.Eventhough the 3.3v is detected on the pin,the clock is not gettin...
Hello, It's a discussion continuity of the thread: https://community.st.com/t5/stm32-mcus-products/ext-interrupt-conflict-on-stm32h7/td-p/742235I replace PA3 instead of PA1, now all interrupt sw works except PA3... whats happen to this PA3 interrupt?...
I can produce a sine wave using DAC1 + DMA on a STMG431CBU6 MCU, but I'd like to increase the frequency (purely as a learning exercise). In the application note https://www.st.com/resource/en/application_note/an4566-extending-the-dac-performance-of-...
Hi ST Support Team, I am using the stm32f103rct6 mcu in my custom board. I am using the inbuild flash API's to write data into the flash memory. I have checked the erase api is working properly, I am able to see the 0xff at all locations without any...
Hi, I'm facing a very strange issue with my G070CBT6-based board... When I start work and power up the board everything works fine for a couple of minutes (let's say 5 minutes ) but later I can observe some disturbances on the reset pin... I connect ...
