I looked for some information about fastGPIO on the Galileo but none of it was related to MRAA.
Some of the most useful links I found are
That discuss the speeds, code and performance of the pins. I found in this link http://iotdk.intel.com/docs/master/mraa/namespacemraa.html an option of pinMode called PIN_FAST_GPIO. I haven’t tested this with the Galileo but give it a try and let us know if you found this useful.
Hi Sergio! First thanks for reply!!
But have some way to do GPIO access directly without using the arduino IDE ? Or some material that can help me to understand create by myself some library for fast gpio running directly on Linux? The performance links I already saw but i don't know how to do it in a C/C++ program, for example.
Btw, the first link is broken D:
You can access GPIOs directly from Linux. In /sys/class/gpio you can find the gpios available and can configure a variety of options. You can see more information here https://anandvetcha.wordpress.com/2014/09/28/galileo-gen2-gpio-control-using-linux/
I didn’t find any information on how to do fastgpio without the use of the IDE. What speeds are to attempting to reach using the fastgpio method?
