I am building a portable medical kit on Intel Atom N240 series, loaded with FC 11.
I am adding sensors (spirometer oximeter) through GPIO, (using RS 232, spi. USB is also an option). I have loaded the module needed to bring GPIO to userspace and I can now set each pin as input/output, the logical values at these pins.
All this I am able to do from both kernel space and user space (writing to /sys/class/gpio
folders).
Initially I would like to start of by adding an LCD or LED display, although there is LVDS interface, I would like to use GPIO since I want to add others sensors through GPIO.
Where shall I start from? There quite a few tutorials on this topics for ARM but none for Intel Atom. If one exists, can you please tell me where it is?
