Hi there,
lately I have reviewed the old code from kernel diff-2.4.9-ac9-rmk1.
There I have found an entry in ucb1200_audio.c of the function
static uint mcp_read_buttons(void)
{
ucb1200_write_reg(UCB1200_REG_IO_DIRECTION, CODEC_ITSY_IO_DIRECTIONS);
ucb1200_write_reg(UCB1200_REG_IO_DATA, 0);
return((~ucb1200_read_reg(UCB1200_REG_IO_DATA)) & CODEC_ITSY_IO_BUTTONS);
}
Is this could equal to the the code of 2.4.18-rmk2 of the function
mcp_sa1100_read??????
Further I found the following functions for h3600:
static void action_button_handler(int irq, void *dev_id, struct pt_regs
*regs)
static void suspend_button_task_handler(void *data)
static int keyEvent(ID * pDev )
static int keyRead(ID * pDev)
How does h3600 devices handel the reading of the buttons? With a demon?
Is a source of the demon on handhelds or somewhere else around?
My goal is to implement something like the code above to make it possible
that I can use the buttons on my device "SIMpad" (SA1100).
I can use any tips.
Thanks for helping
Juergen
