From 7ef58eef7a57c46ab53ed8a26805b58dcffd7010 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Fri, 20 Nov 2009 04:39:41 +0000 Subject: Fixed LowLevel Keyboard demo not saving the issued report only after it has been written to the endpoint. Added support for multiple keyboard keycodes in a single report to the LowLevel and ClassDriver Keyboard demos. --- Demos/Device/ClassDriver/Keyboard/Keyboard.c | 24 +++++++++++---- Demos/Device/ClassDriver/Keyboard/Keyboard.txt | 11 ++++--- Demos/Device/LowLevel/Keyboard/Keyboard.c | 36 ++++++++++++++++------ Demos/Device/LowLevel/Keyboard/Keyboard.h | 1 + Demos/Device/LowLevel/Keyboard/Keyboard.txt | 11 ++++--- Demos/Device/LowLevel/Mouse/Mouse.c | 8 ++--- .../JoystickHostWithParser.c | 2 +- .../MouseHostWithParser/MouseHostWithParser.c | 2 +- .../RNDISEthernetHost/RNDISEthernetHost.c | 2 +- LUFA/ManPages/ChangeLog.txt | 2 ++ LUFA/ManPages/FutureChanges.txt | 3 +- .../StandaloneProgrammer/StandaloneProgrammer.c | 2 +- 12 files changed, 68 insertions(+), 36 deletions(-) diff --git a/Demos/Device/ClassDriver/Keyboard/Keyboard.c b/Demos/Device/ClassDriver/Keyboard/Keyboard.c index ea373a802..2918f5a67 100644 --- a/Demos/Device/ClassDriver/Keyboard/Keyboard.c +++ b/Demos/Device/ClassDriver/Keyboard/Keyboard.c @@ -144,22 +144,34 @@ bool CALLBACK_HID_Device_CreateHIDReport(USB_ClassInfo_HID_Device_t* const HIDIn uint8_t JoyStatus_LCL = Joystick_GetStatus(); uint8_t ButtonStatus_LCL = Buttons_GetStatus(); + static uint8_t PrevUsedKeyCodes; + uint8_t UsedKeyCodes = 0; + if (JoyStatus_LCL & JOY_UP) - KeyboardReport->KeyCode[0] = 0x04; // A + KeyboardReport->KeyCode[UsedKeyCodes++] = 0x04; // A else if (JoyStatus_LCL & JOY_DOWN) - KeyboardReport->KeyCode[0] = 0x05; // B + KeyboardReport->KeyCode[UsedKeyCodes++] = 0x05; // B if (JoyStatus_LCL & JOY_LEFT) - KeyboardReport->KeyCode[0] = 0x06; // C + KeyboardReport->KeyCode[UsedKeyCodes++] = 0x06; // C else if (JoyStatus_LCL & JOY_RIGHT) - KeyboardReport->KeyCode[0] = 0x07; // D + KeyboardReport->KeyCode[UsedKeyCodes++] = 0x07; // D if (JoyStatus_LCL & JOY_PRESS) - KeyboardReport->KeyCode[0] = 0x08; // E + KeyboardReport->KeyCode[UsedKeyCodes++] = 0x08; // E if (ButtonStatus_LCL & BUTTONS_BUTTON1) - KeyboardReport->KeyCode[0] = 0x09; // F + KeyboardReport->KeyCode[UsedKeyCodes++] = 0x09; // F + /* The host will ignore the device if we add a new keycode to the report while another keycode is currently + * being sent (i.e. the user has pressed another key while a key is already being pressed) - we need to intersperse + * the two reports with a zeroed report to force the host to accept the additional keys */ + if (UsedKeyCodes != PrevUsedKeyCodes) + { + memset(KeyboardReport, sizeof(USB_KeyboardReport_Data_t), 0x00); + PrevUsedKeyCodes = UsedKeyCodes; + } + *ReportSize = sizeof(USB_KeyboardReport_Data_t); return false; } diff --git a/Demos/Device/ClassDriver/Keyboard/Keyboard.txt b/Demos/Device/ClassDriver/Keyboard/Keyboard.txt index b1f5c2b53..89dde8305 100644 --- a/Demos/Device/ClassDriver/Keyboard/Keyboard.txt +++ b/Demos/Device/ClassDriver/Keyboard/Keyboard.txt @@ -49,11 +49,12 @@ * OSes (i.e. no special drivers required).
