Hey guys, i want to stablish communication between LM75 and STM32F030C8T6 model.The I2C bus detect device perfectly, but i have a problem in reading temperature from LM75.Like the datasheet says, if i read the 0x00 register it will return the tempera...
HelloI have configured TIM2 to throw an interrupt every 10 ms. Looking at APB1 Timer clocks clocks in the clock configuration, a prescaler of 199 with AutoReload set to 9999 should call the interrupt every 10ms. In reality the interrupt is called eve...

Hello,I am trying to get my RTC module working working, I have setup everything using the stm32cubemx, so far all my peripherals are working but I seem to have an issue trying to setup my RTC which is a totally new experience for me using the STM32cu...
I have to generate a DMA request using GPIO input pin to change the polarity bit of my TIMER which I'm using as PWM(initial polarity is set to HIGH) to LOW which will change by setting the polarity bit to 1. Whenever the GPIO input pin get a rising e...
I'm looking for the .bin file that comes pre-programmed on the board. Anyone know where I can find it? The .zip file on the product page appears to be for a different board/project and also only contains a .hex file. Also if there is source code is a...
Hi, What could be possibly wrong to make the RTC hour keep count up above 23 hour. With some boards it works correctly, going to 00 from 23. but some other keep count up 24, 25... How is that possible? There is any configuration to do that?
