Confirmation of Program Operation in Release buildWe are trying to verify the operation of the program in the Release build. However, when we do [Build with Release] → [Change Debug Configuration(Select the application Release/***.elf)] → [Debug], we...
I’m working on reading an ADC that’s interfaced with an STM32L4RET6, and I’m encountering an issue with data reception when switching SPI modes. Here’s the setup:The ADC has a data rate of 8000 Hz, so I receive a DRDY (active low) signal every 125 µs...
Hello everyone,I'm new to embedded development, and I'm trying to implement a kind of hello-world-level project to get acquainted with STM32 MCU architecture using arm assembly. In particular, I'm trying to set up ADC at STM32F103C8T6 Blue Pill board...
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 ...
