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...
Hi, I want to make a bridge between 2 CAN BUSes with STM32F4. I am trying to listen of interrupts of both CAN on HAL_CAN_RxFifo0MsgPendingCallback and receive a message and send it to another CAN, but it seems that I only receive CAN1 interrupt. CAN2...
Hello,I need to find a solution to generate a pulse through a GPIO...To generate a bit 0, I need to send a level HIGH of 300 ns following by a level LOW of 900 ns minimum.To generate a bit 1, I need to send a level HIGH of 900 ns following by a level...
I am using stm32f429zi discovery board.When I am trying to use SPI peripheral, one bit shift in MOSI is observed with respect to Clock.It is tested in all modes of SPI, still getting the same result in oscilloscope. We are not able to understand this...
Working on a bootloader on the STM32F745 and starting from example code there was the function call CPU_CACHE_Enable.In the original examples, this is called right at the start of main(). I had moved this function call later as I (thought) I wanted t...
Hello,In my project, I sample the ADCs ( ADC1 & ADC2 ) every 1 millisecond. My ADC configuration :VREF = 3VFADC == 8M Prescaler = divide by 83 channels for each ADCSample time - 64.6 cyclesIn order to test my ADC driver, I inject 1HZ sinus. to 1 of ...
Hello,I have a board that use STM32F072C8T6TR reference. After severel weeks of normal use, the STM32 on some boards are not responding anymore. I tried to access the STM32 with STlink Probe, ore by using internal Bootlaoder, without success. After i...
Hello,All I / Os are CMOS and TTL compliant (no software configuration required).For example, as shown in the attached document, the VOH in Table 57 has a different Min value depending on whether it is a CMOS port(a side) or a TTL port(b side).When ...
abbreviations are extremely poorly described throughout the documentation. you have to turn on the fortune-teller mode to understand what is happening. in particular, the UG bit has not been "reliably" deciphered. all documentation is "raw" and made...
selected processor does not support `wfi' in Thumb mode mcu: stm32f103c8 - Ide: stm32cubeide how can I fix this error ?,thank you
