My project is based upon the implementation of a 4x3 keypad.
Iam using the Freescale 1322x MCU board.
On the Freescale 1322x board there are 26 pinouts for connections.
Among the 26 pinouts i have selected the pins 13,15,17,19,21,23,25 pinouts.
The gpio pins on the freescale 1322x chip which are associated with these pins are as follows.
1) 13(Pinout) :- GPIO 2(gpio pin on Freescale 1322x chip)
2) 15(Pinout) :- GPIO 22(gpio pin on Freescale 1322x chip)
3) 17(Pinout) :- GPIO 18(gpio pin on Freescale 1322x chip)
4) 19(Pinout) :- GPIO 21(gpio pin on Freescale 1322x chip)
5) 21(Pinout) :- GPIO 12(gpio pin on Freescale 1322x chip)
6) 23(Pinout) :- GPIO 7(gpio pin on Freescale 1322x chip)
7) 25(Pinout) :- GPIO 6(gpio pin on Freescale 1322x chip)
My query is on the 15(Pinout) :- GPIO 22(gpio pin on Freescale 1322x chip) which is linked to KBI_0_HST_WK, i want to send an interrupt along with a callback function(which is my code) and also an event.
So the above should be a keyboard interrupt and a keyboard event.
So kindly let me know the API for the above wherein i can send the interrupt through an external hardware i.e from a key of a 4x3 keypad.
So when i press a key associated with the Pinout 15 an interrupt should go to KBI_0_HST_WK and do a wake up.
Let me know the API's and methods for the above as early as possible.
Also kindly let me know if i have to send an interrupt to the a gpio pin lets say GPIO 22 which is associated with KBI_0_HST_WK should i use the GPIO registers to send the interrupt or the CRM(clock reset module) registers.
MATTER MOST URGENT
Thanks & Regards
