From 7780fd1c01182ab67d899b78d85a0d3b0d89196f Mon Sep 17 00:00:00 2001 From: Mekaniserad Apelsin Date: Sun, 26 Apr 2015 08:08:54 +0200 Subject: Add mouse support to ADB Adding the makefile options ADB_MOUSE_ENABLE and ADB_MOUSE_ACCMAX. Might have gone overboard with comments, and tried but failed at not adding more than necessary outside the converter/adb_usb/ folder. --- tmk_core/protocol/adb.c | 24 +++++++++++++++++++++++- 1 file changed, 23 insertions(+), 1 deletion(-) (limited to 'tmk_core/protocol/adb.c') diff --git a/tmk_core/protocol/adb.c b/tmk_core/protocol/adb.c index bbff66df03..5c6c99b4fc 100644 --- a/tmk_core/protocol/adb.c +++ b/tmk_core/protocol/adb.c @@ -60,6 +60,7 @@ static inline void place_bit1(void); static inline void send_byte(uint8_t data); static inline uint16_t wait_data_lo(uint16_t us); static inline uint16_t wait_data_hi(uint16_t us); +static inline uint16_t adb_host_dev_recv(uint8_t device); void adb_host_init(void) @@ -121,12 +122,33 @@ bool adb_host_psw(void) // // [from Apple IIgs Hardware Reference Second Edition] +enum { + ADDR_KEYB = 0x20, + ADDR_MOUSE = 0x30 +}; + uint16_t adb_host_kbd_recv(void) +{ + return adb_host_dev_recv(ADDR_KEYB); +} + +#ifdef ADB_MOUSE_ENABLE +void adb_mouse_init(void) { + return; +} + +uint16_t adb_host_mouse_recv(void) +{ + return adb_host_dev_recv(ADDR_MOUSE); +} +#endif + +static inline uint16_t adb_host_dev_recv(uint8_t device) { uint16_t data = 0; cli(); attention(); - send_byte(0x2C); // Addr:Keyboard(0010), Cmd:Talk(11), Register0(00) + send_byte(device|0x0C); // Addr:Keyboard(0010)/Mouse(0011), Cmd:Talk(11), Register0(00) place_bit0(); // Stopbit(0) if (!wait_data_hi(500)) { // Service Request(310us Adjustable Keyboard): just ignored sei(); -- cgit v1.2.3
