#define | VS_SCK_PORT |
#define | VS_SCK_DDR |
#define | VS_SCK_BIT |
VS1001 serial control interface clock input bit. The first rising clock edge after XCS has gone low marks the first bit to be written to the decoder. | |
#define | VS_SS_PORT |
#define | VS_SS_DDR |
#define | VS_SS_BIT |
VS1001 serial data interface clock input bit. | |
#define | VS_SI_PORT |
#define | VS_SI_DDR |
#define | VS_SI_BIT |
VS1001 serial control interface data input. The decoder samples this input on the rising edge of SCK if XCS is low. | |
#define | VS_SO_PIN |
#define | VS_SO_DDR |
#define | VS_SO_BIT |
VS1001 serial control interface data output. If data is transfered from the decoder, bits are shifted out on the falling SCK edge. If data is transfered to the decoder, SO is at a high impedance state. | |
#define | VS_XCS_PORT |
#define | VS_XCS_DDR |
#define | VS_XCS_BIT |
VS1001 active low chip select input. A high level forces the serial interface into standby mode, ending the current operation. A high level also forces serial output (SO) to high impedance state. | |
#define | VS_BSYNC_PORT |
#define | VS_BSYNC_DDR |
#define | VS_BSYNC_BIT |
VS1001 serial data interface bit sync. The first DCLK sampling edge, during which BSYNC is high, marks the first bit of a data byte. | |
#define | VS_RESET_PORT |
#define | VS_RESET_DDR |
#define | VS_RESET_BIT |
VS1001 hardware reset input. | |
#define | VS_DREQ_PORT |
#define | VS_DREQ_PIN |
#define | VS_DREQ_DDR |
#define | VS_DREQ_BIT |
VS1001 data request output. | |
#define | LCD_DATA_PORT |
#define | LCD_DATA_DDR |
#define | LCD_DATA_BITS |
LCD data lines, either upper or lower 4 bits. | |
#define | LCD_ENABLE_PORT |
#define | LCD_ENABLE_DDR |
#define | LCD_ENABLE_BIT |
LCD enable output. | |
#define | LCD_REGSEL_PORT |
#define | LCD_REGSEL_DDR |
#define | LCD_REGSEL_BIT |
LCD register select output. | |
#define | LCD_LIGHT_PORT |
#define | LCD_LIGHT_DDR |
#define | LCD_LIGHT_BIT |
LCD output to switch backlight. | |
#define | IR_SIGNAL_PORT |
#define | IR_SIGNAL_PIN |
#define | IR_SIGNAL_DDR |
#define | IR_SIGNAL_BIT |
Infrared decoder signal bit. |
