I have the stm32f4 discovery kit. It's true, natively doesn't have an UART communication from USB but I connect the pins RX and TX of debugger to USART2, step and step from datasheets. I would have to see the device in the port on my Device Manager ...
Hello,I want to improve the electromagnetic compatibility of my design and it seems that the worst part of the circuit is the STM32H7 <> SDRAM IS42S32800J-7TLI communication.After a day in a specialized lab I know that I am out of the CE range : I ha...
It seems that I'm having problems with the pins configured as alternate function.If I configure the same pins used by SPI or USART as simple gpio outputs, I can see them toggling with the logic analyser. but when I configure them as SPI (alternate fu...
dma don't work with adc. After first writing dma set flag TEIF. Value wasn't written to buffer. I ported example (adc dma transfer) from stm32h743 to 723, it have this error too.
Hi,I'm trying to configure manually OCTOSPI registers in order to implement Hyperbus protocol but when I try to write registers it has no effect...I'm using that command: OCTOSPI1->CR = OCTOSPI1->CR | (0x1 << 0);But the register keep it's value 0.
I'm working on a project with an STM32F3 MCU and I've been running some test-code on register level, but I have had trouble with the timer and making pin PE8 blink. The result from this code is that it will turn the LED on but it won't toggle the pin...
Can the combined PWM signal be the AND of two reference PWMs in which one is negated?This is what I would like to do. Combined PWM signal = OC1Ref AND NOT(OC2Ref)If I could set the polarity of the two reference PWMs differently, I think that would ...
HelloI am (still) using CooCox IDE + STM Periph Libraries 1.5.0In my code I finally enabled ADC interrupt , but surprise, the code is ending into default handler regardless the fact that I have a function with the same name as the adc handler used in...
Can Somebody please recommend a starter development board and peripherals. I a new to STM32 and microcontrollers - complete newbie. I have a project I would like to teach myself on which involves an mcu that takes input values, performs calculation, ...
