Hello,
I'm considering STM32 for my hobby. GPIO speed is fundamental feature for me. I have tested that LPC2148 Fast GPIO could switch output on single cycle - soo.. if you have 72Mhz, you can produce 'square' wave at 36Mhz (linear set,clear,set,clear code)
There are many clocks dividers for GPIO for STM32 - but does someone done such test for STM32 ? They say that APB2 is the fastest one - can it match a FGPIO from NXP ?
Thanks for any info.
