Using Keypad on dm365evm when running Android.

Hi Rohit,

You can connect USB mouse/Keyboard to test functionality.

Run getevent command and check  whether you getting keypad events on console.

The <keypad driver name>.kl should be present in /system/user/keylayout folder of your filesystem to make keypad work with Android.

Please refer to following link and add <keypad driver name >.kl file in /system/user/keylayout folder of your filesystem and try.

Good Mroning Pankaj ,

                      I had done some modification as by reading the code, value and input parameters which will be recorded in /dev/input0 for each key, when pressed.

we have 16 GPIO keys connected in matrix  style .

I had done some modification regarding the TWL4030_keypad.kl which was in /system/usr/keypad/.

This is as per my modification :-

I had modified the OMAP3EVM keylayout to DM365EVM Keylayout

-------------------------------------------------------------------------

#DM365EVM keylayout

key 139   MENU                          WAKE_DROPPED
key 74    BACK                            WAKE_DROPPED
key 80    DPAD_UP                    WAKE_DROPPED
key 28    HOME                           WAKE
key 108   EXPLORER               WAKE
key 78    VOLUME_UP
key 105   DPAD_LEFT              WAKE_DROPPED
key 79    DPAD_CENTER         WAKE_DROPPED
key 106   DPAD_RIGHT           WAKE_DROPPED
key 103   SEARCH                     WAKE
key 168   VOLUME_DOWN
key 208      SOFT_LEFT            WAKE_DROPPED
key 128   DPAD_DOWN          WAKE_DROPPED
key 164   SOFT_RIGHT           WAKE_DROPPED
#key 105   POWER                  WAKE

---------------------------------------------------------------------------------------------

FYI : 1) I read the code values by cd  /sys/proc/

                                                           and cat kmsg.

          2) The key 139   MENU                          WAKE_DROPPED

                           139 is the code of  menu button on the board (SW14). Am i entering the key value correct ? if not then what is the keyvalue here?

I have done this, but i am not able to operate the keypad, also some keys work for a while like , if i press Right button , the screen may navigate to right and left  navigate to left, but it wont work all the time.

Can you please guide me in this issue.

THANKS AND REGARDS

Hi Rohit,

You can map any key for a specific function.

Please look at your keypad driver code for key codes and update KL with your key codes as per functionality needed.
