How fast can it go?

Just tried to see how fast I can run my STM32F103 (genuine chip) while blinking a led and send strings over uart.

128Mhz! (8Mhz crystal with the pll running at 16x).

Pretty amazing for a chip spec'd at 72Mhz.

if you do dma, then you can blink the led with your code.
and if you do dma and use a hardware timer to blink the led,
then your stm32 can simply run an idle loop and count interrupts :lol:

Code: Select all


void loop() {
	asm("wfi");
}
