IRQ: 21 GPIO: BTUART (Seems GPRS was activated and email was being checked, Ok, I triggered mail download delibratly over GPRS and this IRQ kept triggering....) IRQ: 31 GPIO: (RTC1) After the clock was activated, a lot of BT UARTS appeared and a message that you have X unread msg in my email inbox (The email checking in INBOX is configured to check emails every 10 mins) so probably used by WINCE to trigger scheduled tasks. IRQ: 149 GPIO: 115 (Clicking any where on the screen generated these messages, so it seems that it the TouchScreen IRQ and that it was a wrong interpretation the other day, its not a backlight "switch on" GPIO) IRQ: 17 GPIO: LCD (Backlight) If i press the hardware key "Message", I find that a keypad IRQ is triggered "4" plus IRQ "17" and the screen lights up, Now, it seems that IRQ 17 is for backlight. (Whenever the "hardware" key is pressed, this IRQ is triggered, irrespective of the fact that backlight was on or off) IRQ: 4 GPIO: Keypad This IRQ gets triggered when the any "Hardware" button is pressed. IRQ: 25 GPIO: DMA IRQ: 128 GPIO: 94 Joypad "Right" IRQ: 129 GPIO: 95 Joypad "Left" IRQ: 130 GPIO: 96 Joypad "Up" IRQ: 132 GPIO: 98 Joypad "Down" IRQ: 131 GPIO: 97 Joypad "Centered" IRQ: 23 GPIO: MMC MiniSD card action. Ok, confirmed, when i took the mini card out, nothing happened, but as soon as i inserted this card back in slot, a lot of IRQ 23's. During this event, a couple of 47s were triggered as well, i believe wince does that to see what name to give to the card as, when the BIG SD is already present, the name of the MiniSD is "Storage Card2" other wise its "Storage Card". IRQ: 47 GPIO: 13 BIGGER SD card action. IRQ: 20 GPIO: STUART Looking for IRDa transmission.
