Hi.Faced the problem of prinyf () function execution speed.Wrote a simple speed testHAL_GPIO_TogglePin (GPIOE, GPIO_PIN_8);uint8_t text [256] = {0};for (uint32_t i = 0; i <256; i ++){sprintf (text, "% - 5.2f", (i + 10.0 / 2.0));}HAL_GPIO_TogglePin (G...
I'm going to post this here, as a lot of people don't appear to be paying attention to the unravelling situation in the semi-conductor space.ST has it's own fabs, but the business environment is likely to push capacity toward highest margin wafers/di...
Hello,I run into problem for selecting TIM2 as my pwm output. As it turns out, it is only output capable. But I need to get processor independent 3kHz 50:50 PWM signal with no AF functional PWM.Any simple idea how can I toggle with 50% 3kHz duty cycl...

Hello ST,I'm trying to launch a debug session for STM32f769i-disco using openocd and gdb in linux. I've install openocd(0.10.0), gdb and gdb-multiarch tools in linux.This is the below log after launching openocd with my board's config file.openocd -f...
I can't seem to get anything out of my I2C port. The is the first time I've done it using the standard peripheral library. I seem to get about 2clks at the start when monitoring it with an oscilloscope, then nothing. It is as if there is a periphe...
I'm currently using TIM2 on an STM32F373 as a 32bit quadrature encoder interface, however I need to extend this to 64 bits. Can I cascade a second 32bit counter (e.g. TIM5) as a slave whilst still maintaining the ability to count up & down ? Thanks
I've edited this post to make it more useful to others.We are well into development of a board at work using an STM32F072RBT6 MCU. I just wrote a quick from scratch test using a NUCLEO-F072RB board to verify things. I'm not sure of the exact problem,...
Hello,I'm working with STM32F427VIT6 microcontroller. BOOT0 is connected to GND through 10K resistor. The NRST state is high.My problem is when I power up the board, the microcontroller code execution seems to not start. The execution only starts if ...
