Hello,In my project I need to generate 1s on, 1s off PWM signal in hardware.First I checked if my PWM works with simple project, and it does.But following AN4776 for N-pulse waveform generation application example - part 1.LL_APB2_GRP1_EnableClock(L...
I just had my first STM32 pcb done and I've been following the reference designs and checked many times everything that there is no shorts etc. However when I power the circuitry 3.3V side draws >200mA and the STM32L4S5ZIT6 does heat up when looked t...
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
