X-Git-Url: http://git.zarvox.org/shortlog/static/%7B%7B%20url_for%28%27main.login_page%27%29%20%7D%7D?a=commitdiff_plain;h=c18d4bb915d84ff09ee45e8f1101e62c34bc813e;p=usbsnes.git Recognized as a joystick, timer verified working. Actually gets recognized and polled correctly. Increments a bitmask revealed in the button state every second. --- diff --git a/Makefile b/Makefile index fa79efa..6941d0c 100644 --- a/Makefile +++ b/Makefile @@ -4,7 +4,8 @@ F_CPU = 18000000 # in Hz FUSE_L = 0xd7# see below for fuse values for particular devices FUSE_H = 0xd9 -AVRDUDE = avrdude -c stk500 -B 2 -p $(DEVICE) -P /dev/ttyACM0 # edit this line for your programmer +#AVRDUDE = avrdude -c stk500 -B 2 -p $(DEVICE) -P /dev/ttyACM0 # edit this line for your programmer +AVRDUDE = avrdude -c avrispmkII -B 10 -p $(DEVICE) -P usb # edit this line for your programmer CFLAGS = -Iusbdrv -I. -DDEBUG_LEVEL=0 OBJECTS = usbdrv/usbdrv.o usbdrv/usbdrvasm.o usbdrv/oddebug.o main.o snes.o diff --git a/main.c b/main.c index e34a7cf..9e8ccb8 100644 --- a/main.c +++ b/main.c @@ -10,37 +10,48 @@ uint16_t pollSnes(); -PROGMEM char usbHidReportDescriptor[28] = { - 0x05, 0x01, // USAGE_PAGE (Generic Desktop) - 0x09, 0x05, // USAGE (Game Pad) - 0xa1, 0x01, // COLLECTION (Application) - 0x09, 0x05, // USAGE (Game Pad) - 0xa1, 0x00, // COLLECTION (Physical) - 0x05, 0x09, // USAGE_PAGE (Button) - 0x19, 0x01, // USAGE_MINIMUM (Button 1) - 0x29, 0x10, // USAGE_MAXIMUM (Button 16) - 0x15, 0x00, // LOGICAL MINIMUM (0) - 0x25, 0x01, // LOGICAL MAXIMUM (1) - 0x95, 0x10, // REPORT_COUNT (16) - 0x75, 0x01, // REPORT_SIZE (1) - 0x81, 0x02, // INPUT (Data, Var, Abs) - 0xc0, // END_COLLECTION - 0xc0 // END_COLLECTION +PROGMEM char usbHidReportDescriptor[] = { + 0x05, 0x01, // USAGE_PAGE (Generic Desktop) + 0x09, 0x04, // USAGE (Joystick) + 0xa1, 0x01, // COLLECTION (Application) + 0x09, 0x01, // USAGE (Pointer) + 0xa1, 0x00, // COLLECTION (Physical) +// 0x85, 0x01, // REPORT_ID (1) + 0x09, 0x30, // USAGE (X) + 0x09, 0x31, // USAGE (Y) + 0x15, 0x00, // LOGICAL_MINIMUM (0) + 0x26, 0xff, 0x00, // LOGICAL_MAXIMUM (255) + 0x75, 0x08, // REPORT_SIZE (8) + 0x95, 0x02, // REPORT_COUNT (2) + 0x81, 0x02, // INPUT (Data,Var,Abs) + + 0x05, 0x09, // USAGE_PAGE (Button) + 0x19, 1, // USAGE_MINIMUM (Button 1) + 0x29, 8, // USAGE_MAXIMUM (Button 8) + 0x15, 0x00, // LOGICAL_MINIMUM (0) + 0x25, 0x01, // LOGICAL_MAXIMUM (1) + 0x75, 1, // REPORT_SIZE (1) + 0x95, 8, // REPORT_COUNT (8) + 0x81, 0x02, // INPUT (Data,Var,Abs) + 0xc0, // END_COLLECTION + 0xc0, // END_COLLECTION }; -/* -typedef struct { - uchar buttons[2]; -} report_t; -*/ + typedef struct { - uint16_t buttons; + //uchar id; + char x; + char y; + uchar buttons; } report_t; static report_t buttonState; static report_t reportBuffer; static uint8_t pollInProgress = 0; +static unsigned char idleRate; +static uint8_t interrupt_count = 0; usbMsgLen_t usbFunctionSetup(uchar data[8]) { + usbRequest_t *rq = (void *)data; /* The following requests are never used.
