Resolved! stm32f411 spi4 low clock speed
Hello!I have problem with spi4 clock speed. I want to drive a lcd tft display but spi clock is max 500Khz, baudrate prescaler set to SPI_BAUDRATEPRESCALER_2. Is very weird. Initial setup was made with CubeMX to 48Mbit/s. APB2 clock is set to 96Mhz. I...

Hi guys,I'm using STM32LO and i try to implement a code who aquire data of a sensor every 10 second in a fix day in a week. The rest of the time, the ship is sleeping.I'm trying to do that interruption with RTC and i configure the RTC and program my ...
STM32L451VC: Problems with ADC.
Hello, I'm working with a PCB based on STM32L451VC MCU and I have different problems with the ADC. I'm trying to measure an input channel using the HALs provided by the STM32CubeMX but I can't achieve it. The main problem is that the bit ADRDY from A...
Have a question concerning specifically the STM32F479 NRST pin, but this may be applicable to other STM MCU’s as well. Is this Pin an Input/Output pin ?
I read in section 6.2.1 of the STM32F479 reference manual that this Pin will Output a 20us reset pulse during Watchdog and other internal events. I did not find any Output characteristics for NRST and the statement in section 6.2.1 was stated almost...
Passing parameters from gcc command line
Hi,I'm attempting to pass a parameter for a conditional compile from the gcc command line to my application. I have two build makefiles, one for debug and one for release. We have some code that's only meant for the release build. So far, so good. If...
Resolved! RM0454 Rev. 2, Table 1, "Availability of peripherals", is not correct.
STM32G070 is *NOT* supposed to have DAC, UCPD etc., at least not "officially"?!
Sine wave interpolation for pwm generation
Hey everyone,I'm still busy scoping out how to do this. I've been looking int methods to generate sine waves and so far it looks like some of the methods use lookup tables or trig functions from cmsis.Although I don't think this would be very ideal, ...
