From ac70ddd0a1c412bb54def48e53caaebd0b5c9c61 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Mon, 8 Jun 2009 07:34:16 +0000 Subject: Converted Host mode demos to schedulerless. Fixed host mode broken due to earlier Start-of-frame event experiments. --- Demos/Host/LowLevel/KeyboardHost/KeyboardHost.c | 100 ++++++------------------ Demos/Host/LowLevel/KeyboardHost/KeyboardHost.h | 40 +++++----- Demos/Host/LowLevel/KeyboardHost/makefile | 4 +- 3 files changed, 46 insertions(+), 98 deletions(-) (limited to 'Demos/Host/LowLevel/KeyboardHost') diff --git a/Demos/Host/LowLevel/KeyboardHost/KeyboardHost.c b/Demos/Host/LowLevel/KeyboardHost/KeyboardHost.c index 2b9bb2b0b..64bcf0906 100644 --- a/Demos/Host/LowLevel/KeyboardHost/KeyboardHost.c +++ b/Demos/Host/LowLevel/KeyboardHost/KeyboardHost.c @@ -36,18 +36,27 @@ #include "KeyboardHost.h" -/* Scheduler Task List */ -TASK_LIST -{ - { .Task = USB_USBTask , .TaskStatus = TASK_STOP }, - { .Task = USB_Keyboard_Host , .TaskStatus = TASK_STOP }, -}; - - /** Main program entry point.
