The display operation occurs by transferring data and con- trol information from the micro-controller to RAM through a serial data interface. It can execute full-screen display automatically, as well as specific functions such as charac- ter background, bordering, shadowing, blinking, double height and width, font by font color control, character but- ton boxes, frame positioning, frame size control by charac- ter height and row-to-row spacing, horizontal display resolution, full-screen erasing, fade-in/fade-out effect, win- dowing effect, shadowing on window and full-screen self- test pattern generator.
MTV038 provides 544 fonts including 512 standard fonts and 32 multi-color fonts and 2 font sizes, 12x16 or 12x18 for more efficacious applications. The full OSD menu is formed by 15 rows x 30 columns, which can be positioned anywhere on the monitor screen by changing vertical or horizontal delay.
The MTV038 auto sizing video measurement module measure the timing relationship among HFLB, VFLB, and R, G, BIN with 12-bit resolution at the speed related to the OSD pixel clock. And the R, G, BIN input level can be programming by software. MCU can get the measurement data, active video, front porth and back porth, through I2C bus read/ write operation to keep the appropriate display size and center.
