Hello! I'm using STM32L422 and I'm having trouble with setting up the PLL above certain frequencies. Are there any specific configuration requirements when setting up PLL at high frequencies?

2021-08-11
I use 8MHz crystal as the input for the PLL. I'm using a timer and a LED to verify frequency, aka the LED should blink at 1Hz. Everything works fine until 48MHz, after which the STM seems to fail - led doesn't blink and the debugger does not know wh...

STM32L496 SPI 16 clock cycles instead of 8

2021-07-05
So I have configured the SPI peripheral with a data frame of 8 bits. However, in the scope, there are 16 cycles in total. The first byte is okay, and outputs the loaded byte, however after the first 8 cycles, there are additional 8 cycles. The issue ...

What is the exact procedure to set up the STM32L496 device so that the IDR will output the input of a pin?

2021-06-22
Currently, it seems that the IDR of any port updates only when the IO is configured as an output and does not record the state when the IO is configured as an input. Here is two examples of simple code for each situation1) Both PC2 and PC15 is set as...
