Vehicle Instrumentation AV character video overlay display panel can be characters, video overlay display

Digital video overlay driver board, digital control panel overlay, video overlay panel, dual-channel controller card, video overlay controller, are our company developed the production of products 1, a working principle: MCU (single) tablet machine, ARM, DSP, control display, AV video signal dual channel, realistic video and the MCU can switch the display or overlay, the reality can be easily transparent, opaque, window, superimposed MCU display 256 colors .64 K color options. 2, FX-VM4824C256A is an AV, MCU Combo LCD digital display panel, control panel display has three channels: two analog video signals (CVBS) channels and an MCU digital display channel. Video signal path to accept a composite video signal (CVBS), is displayed on the LCD true color; MCU with 8-bit data bus channel or IO mode and MCU interface, can display 256 colors. In order to facilitate the operation, improve the display speed, the controller accepts the ranks of coordinate values ??directly, no need to calculate memory addresses. The controller uses 512K SRAM cache, display capacity, you can display the contents of the cache 4. In addition the controller also has an address automatically add a function for picture display has a very high speed. 3, 4, Function: 5, ● Support single point of writing (for displaying bitmap graphics) 6, ● Support 8:00 write (suitable character display) 7, ● support multi-write (suitable for fill or draw horizontal lines) 8, ● Hardware clear the screen faster (clear full screen only 2.5 milliseconds) 9, ● direct x, y coordinate input, without conversion 10, ● Software BUSY signal, compared to the hardware BUSY signal, you can save an I / 0 lines 11, the situation is a single point of writing, the BUSY signal can not be read, a single point of writing is to read out the color values ??in the memory 12, the situation two 8:00 write, for the slow CPU, do not need to read the BUSY signal, for fast CPU (such as DSP ), can be 13, or add instructions to read the BUSY signal delay 14, the situation is more than three points clear screen to write or hardware, you need to read the BUSY signal to determine whether the operation is complete. Of course, if you do not read BUSY 15, signal, you need to add instruction latency. 16, the software BUSY signal relative to the instruction latency, and enhance the program's portability and flexibility. 17, ● column coordinates automatic function, a single point of writing, the column address is automatically incremented by 1, 8:00 write column coordinate automatic 8, column coordinates multi-point automatic write number of bytes written, hardware clear screen, the coordinate automatically moved to the end of the screen. End of the line when the coordinate moves automatically when the wrap. 18, ● Character transparent write function, suitable for use in dot matrix graphic overlay characters or Spanish. 19, ● support Innolux, Han Choi, Chi Mei Corporation TFT screen simulation. FX-VM6448C256G V1.2 FX-VM8048C256G V1.23 FX-VM8060C256G V1.23 1. Supports two composite video input (CVBS), automatic identification of PAL and NTSC system 2. Supports 8-bit data bus (or IO analog) Interface , can be any 8/16/32 bit microcontroller, ARM, DSP and other interfaces 3. supports hardware quickly clear the screen, supports single point of writing, 8:00 to write, to write multi-point function to facilitate the realization of graphics / display four characters, etc. Direct input X, Y coordinates, no need to calculate the specific memory address 5. support the open window, can open the MCU in the video window can also be opened in the MCU video window 6. supports transparency for a color display can be transparent overlay on the video characters or graphics. 7 selectable AV top top or MCU, the MCU facilitate the achievement of AV and switched digital video overlay driver board, digital control panel overlay, video overlay panel, dual-channel controller card, video overlay controller, have any questions you can always consult me
