STM32H7 timer interrupt slightly too fast
I am using TIM2 on a STM32H7 to generate interrupts - e.g. every 1 ms. Using the formulas from the documentation, Update_event = TIM_CLK/((PSC + 1)*(ARR + 1)*(RCR + 1)), solving for ARR and using RCR = 0 we getARR = 1/(Update_event * (1 + PSC) / TIM_...
RTC hours keep counting after 24 hours
Hi,I use RTC on a STM32L073. Every 12hours, I receive a date and time to set to the RTC. (Sometime, like 1% of the time) After writen the new RTC value, the RTC doesn't overflow after 23h59min59sec and keep counting without incrementing day. I can ha...
Resolved! STM32H7 Power down sequence
About Power-Down Sequence (Device : STM32H7B0xB)Datasheet : DS13196 - Rev 6 Page 13"During the power-down phase, VDD can temporarily become lower than other supplies only if the energy provided to the microcontroller remains below 1 mJ. " Could y...
Multi channel ADC + SPI + I2C
I'm using STM32 NUCLEOH743ZI2 board were I have written a code which consist of Multi channel ADC using DMA with timer, SPI and I2C protocols. SPI and I2C is not working whenever multi channel ADC is enabled else SPI and I2C is working fine. We are u...
Resolved! F411 System Clock Configuration with Internal Clock
I have been working F411RE Nucleo board with LL library for quite some time. I found the sample code for SystemClock_Config uses external oscillator as showed below. I wonder if there is any sample for internal oscillator. /* Enable HSE oscillator *...
Creating a non cacheable area of RAM on STM32H7A (B)
Using the linker script - How would I assign an area of AXI SRAM1 that is not cacheable by DCache? I am currently having problems with DMA transfers to the PWM peripheral when DCache is enabled (I think this is because I am sending 8bits to the HAL_T...
Trusted Firmware-M for STM32U5 or STM32L5
Hello，has anyone run TF-M successfully on STM32U5 or STM32L5 ? Does ST provide examples for this? I have NUCLEO-L552ZE and NUCLEO-U575ZI board.Looking forward to your reply!
Data storage on cloud using STWINKT1B
I know that there are firmware files to store data on sd card but i just wanted to know if there is a way to store raw sensor data on the cloud directly using the board?
