STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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_...
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...
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...
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...
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 *...
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...
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!
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?
Hello,I have implemented some source code on my original borad with STM32H743.(ex. use HAL_UART_DMA, HAL_SAI_DMA, and more.)I run without Breakpoint, but HardFault occurs.However, I run with Breakpoint, HardFault does not occur.According to the Fault...
