Resolved! How can I prevent the I2C from getting interrupted?

There's a sensor applied to the I2C as a slave. Also on this microcontroller there's a communication running on the UART-Interface in blocking mode. If the UART has to transmit a huge amount of data, it seems that the I2C (also blocking mode) can get...

stm32f103rbt6 i2c1 remap not working

Which peripherals clock need to be enabled?

For the most of the peripheral (e.g. ADC1) it is obvious, but what is withLL_APB2_GRP1_PERIPH_SYSCFG or LL_APB1_GRP1_PERIPH_PWR? Does the voltage regulator work, if PWR peripherals clock is disabled?

STM32L0x2: Combine two comparator outputs

I have a STM32L072KB microcontroller and want to combine two analog signals (they represent a kind of "quadrature encoded signal" with a 50% duty cycle) into one "combined digital output signal", which have the doubled frequency (for my purpose the d...

Resolved! delay function based on timer, overflow safe?

Hello Everybody,I was thinking about a flexible way to implement a µs or ms delay function with a free running timer as tick source. One of the biggest problems that comes to my mind is the overflow problem when the timer wraps around, so that some c...
