From 3d2e10bcbd13ec48decafe49f32afcc12c5e185a Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Sun, 10 Sep 2006 02:00:40 +0000 Subject: Added remote backlight on hold option to players with remote hold switch. Disabled IRQs while reading pcf50606 ADC. This seems to have stopped buttons becoming unresponsive when using remote. Maybe fixes other button glitches as well? git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10911 a1c6a512-1295-4272-9138-f99709370657 --- firmware/backlight.c | 57 ++++++++++++++++++++++-- firmware/drivers/adc.c | 2 + firmware/drivers/button.c | 10 +++-- firmware/export/backlight.h | 23 ++++++++-- firmware/target/coldfire/iaudio/x5/adc-x5.c | 2 + firmware/target/coldfire/iaudio/x5/button-x5.c | 16 ++++--- firmware/target/coldfire/iaudio/x5/pcf50606-x5.c | 2 +- 7 files changed, 92 insertions(+), 20 deletions(-) (limited to 'firmware') diff --git a/firmware/backlight.c b/firmware/backlight.c index 6f7432c9e2..bf88cbe9bc 100644 --- a/firmware/backlight.c +++ b/firmware/backlight.c @@ -178,6 +178,9 @@ static int remote_backlight_timeout = 5*HZ;
