Hi,
are there symbols or similiar to get the input clock frequency for peripherals?
Im especially curious about the CAN clock.
Maybe its derived from the peripheral bus frequency. How to get it? Is it fixed?

Also see section 3.2 in technical reference manual
No mention of can yet but probably APB clock

Thanks!
Yes, it looks like CAN runs with APB speed/gets the clock from it.

Re: Where to get peripheral input clocks
I also search an easy way to get the input clock frequency for peripherals.
Need the XCLK for OV7670 without the LEDC-module.
Free running (with start/stop) at a GPIO-Pin(frequ. 10 to 48 Mhz)..
