Hi All,
I've used the STM32F4 for a few projects, and was considering it for a
time tagger for a DMTD system. I have a question about the clocking
though that someone may be able to help me with.
The 32F4 (like lots of similar ARMs) uses a PLL to generate the internal
clocks from much lower frequency clock or crystal. Has anyone quantified
the stability of the synthesised clock?
Thanks,
david

I can't recommend warmly enough the Discovery board from STM.
It sports a Cortex ARM M4F that can run at 180 MHz, has a native
IEEE compliant floating point core, 2MB flash and 256 kB RAM,
and a wealth of interesting peripherals on chip, TFT display touch
enabled included. And at 23.52 USD is cheaper than a much
less powerful Arduino...
I implemented on it a fully featured SDR, without using any opsys,
talking directly to the bare metal using the Keil IDE/compiler.
A joy to use. Look here :
