HelloI am testing new MCU's. I have a ST-Link V2 and using a STM32F401CCU6.At the start I had a simple LED flasher application however after I could not run it I started stripping everything out.This is when I saw that I can actually not even run an ...

Hi.I have the following code. However when I try and update the arb value with anything it just does not reflect on the pin.Currently it is running a stepper motor. The stepper motor moves one step every time the pulse goes high.With that in mind I a...

Can someone please explain to me how this is even possible on the same device? They are the exact same device yet I can not seem to get the same pin config in different projects.The one project somehow got the PIN Layout where PB6(SCL) and PB7(SDA)...

Hi.I tried using DMA with I2C before using interrupts and I seem to get the same problem that still remains unsolved.This time around I decided I will try and not use any interrupts to make things a bit simple. However I am still getting the same res...

Hi I am having some issues where my MCU ( stm32f030C8T6 ) seems to get stuck in a while loop when using I2C1 and a AS5600 IC.I will paste the code below but give some more detail on the issue here.In the function named "void I2C1_Write_DMA(uint8_t sl...

@Tesla DeLorean This is another strange thing going on. All the registers have this Error message while I can still step through. If I use the HAL generated code it runs fine.@TDK Sorry but I am not 100% sure what the flag is I have to watch to be r...

I figured it out.In my case it seems like the STOP Flag will literally never go high and instead one should rely on the TC Flag. When the STOP gets sent onto the bus the Flag only then goes up. Which is kind of obvious but surprisingly not obvious wh...

Hi @gbm I tried enabling it in line 31 on the code shown above.I basically added this -> "RCC->AHBENR |= RCC_AHBENR_GPIOCEN".However it is still doing the same.When I activate the BusPirate pull ups it gives me this on the sniffer before getting stu...

I just want to get this version working and then I will look into HAL. Thanks

So I enabled GPIOC by enabling the clock for it before setting anything else for PortC?"RCC->AHBENR |= RCC_AHBENR_GPIOCEN;"Also the I2C is on GPIOB right? So the GPIOC has to be enabled non the less? Thanks
