maple at 75 mhz how much time does toggling a pin take? working with sensors their is a window of time for me to respond it must be x long but not y it is too long.

Max clock is 72 MHZ (not 75MHz) but GPIOs toggle at up to 18MHz - see Maple's docs.

72 mhz sorry GPIO humm I am looking http://leaflabs.com/docs/maple/gpio/
where did you find that?I see the SPI section has :
SPI_18MHZ
SPI_9MHZ
SPI_4_5MHZ
SPI_2_25MHZ
SPI_1_125MHZ
SPI_562_500KHZ
SPI_281_250KHZ
SPI_140_625KHZthis line looks strange how could it be faster than the clk?
SPI_1_125MHZreferencing:

Because that's 1.125MHz

I have mention to Leaflabs that they need to combine all their web pages into an orderly
easy to find format. The data is scattered everywhere and for a newbee it is very hard for them to find the infomation they need. I think they have a higher priority by completing the next "stable release" in mid Oct.Posted 5 years ago # -
organisation of open hardware and documentation I have my own site if you have sugjestions I would like a template. :)
GPIOs toggle at up to 18MHz
I found that thanks.
I see adafruit has a similar template for some of their projects.
Info
Design
make
or something....where would you put pc code and micro code of a system? software , firmware ???

First, I don't work for Leaflabs.
Leaflabs have a Github site with all the code.
