Which MCU is better for Timer?

[nietz12]

Hello.

I need Timer for send high speed data.

To send data, i need at least 115200 fps.

Can you recommend which MCU is perfect for me?

Send how? Using some protocol? Why do you need a timer for that?

oh, I'm using led to send data(e.g. 10110010).

so that I need to control GPIO as faster as possible.

Could you recommend to control high speed GPIO?

It's always better to use dedicated hardware rather than generic solutions. In this case, as you want to transmit series data, you should probably be looking at SPI rather than timers.

To get a grip on the problem, I'd recommend you to get any cheap Nucleo board - start perhaps with the 'F4 family, that will get you to the upper-mid-range of what's available - and experiment there. You will then see if its performance is sufficient or not.
