OSD Click features the MAX7456 single-channel monochrome OSD module with integrated EEPROM memory as well as two RCA sockets. It is used to create on-screen menus and other video overlays - such as custom graphics, company logos, time and date, etc - using 256 user-programmable characters or pictographs. It is NTSC and PAL compatible and displays up to 16 rows x 30 characters. The MAX7456 has an internal sync generator. OSD Click communicates with the target microcontroller via mikroBUS SPI (SDI, SDO, SCK, CS#), RST, LOS, HSYNC and VSYNC lines. The board is designed to use a 5V power supply only. A green LED diode indicates the presence of power supply. |
