medical kit on intel atom having fc 11
I am building a portable medical kit on intel atom N240 series, 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).
Now i need to add these sensors to the board,where should I start of to understand the way these sensors work( their mode of tramission)how do I code to access these sensors.
Initially i would like to start of by adding an LCD or LED display, Where shall i start from. There quite a few tutorials on this topics for ARM but none for intel atom, if 1 exist can you please suggest me where it is
Thanks in advance.
