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...
Hello,I'm trying to read the pulse counter with a timer on STM32H747. The counter produces pulses up to 100KHz on one timer channel and high \ low signal to define the direction.I tried two approaches.Reference manual says, as I understand, that such...
My SPI gets stuck (waiting for RX register not empy flag, <SPI1->SR & 1> that never arrives). The operation is written with registers, not HAL.BUT! it only gets stuck after a fixed number of successful repeated operations, all the same, inside a loo...
I want to make 3 pwm with the timer1 on an stm32f103c8t6 and when the timer reaches its reset value an interrupt should be generated. I tried a lot but nothing worked. Can someone please tell me how I do this?
HiSTM32H7A3VG is one of the few stm32's who fit my requirements. This is however sold out on most platforms. Can some one comment on that? Is this chip still in production at all?
I wrote the below assembly macro in startup.S file..macro DEBUG_ToggleLED88 /*Enable clock to the Peripheral Set the pin to output Toggle PD14 */ .equ RCC_BASE, 0x58024400 .equ GPIOD_BASE,0x58020C00 .equ AHB4ENR_OFFSET,0x0E0 .equ RCC_AHB4...
Hi!To give some background, I am trying to interface SDIO over the STM32F429I-DISC1 board by configuring the pinouts to enable SDIO 4-bit Wide Bus and then connecting it to a SDIO breakout board.In the reference manual I checked the clock configurati...
Hi,I would like the apply the DAC values of my STM32H723 together with an external event (external trigger). This event is a falling edge. Is this possible at all? The problem is: No matter how I configure the EXTI line (falling or rising), the DAC v...
i try to crash my code to check the watchdog timer is reseting the code or not. for crashing my code i use timer interrupt. i.eTIM2_IRQHandler(){---------------;---------------;}TIM_IRQHandler() instead of TIM2_IRQHandler . so, code will be crash at ...
I'm using a STM32L152C-Discovery and a USB-RS232 adapter to receive data via UART protocol from the board. The system clock is 32 MHz and I'm using a baud rate of 115200 and no parity check. To view the messages on the PC, I use Putty configured cons...
We have 1,000 boards with STM32L071CBT6, 20 of which cannot be connected to the MCU with Jlink, but can be connected to the MCU through USART. Connect the USART and use the system Bootloader to burn the program to Flash normally, but the program can...
