STM32F103C8T6 -- timers and uarts
The STM32F103 has 3 uarts. They all seem to be equally useful and I have used them at baud
rates up to 115200 and they will certainly go higher. UART1 is on the fast peripheral bus
and may get a faster clock, but it all seems to work out the same once you get the baud rate set.
The STM32F103 has 4 timers.
Each timer has 4 channels.
Some diagrams label these as "PWM" channels, which they certainly can be.
They are quite versatile.
Timer 1 is "special" and is called an "advanced control timer" in the datasheets.
Timers 2,3,4 are called "general purpose timers".
