BIOS SOFTWARE UPGRADE VIEWSONIC VX910 19” Color TFT LCD Display

UPGRADE THE BIOS SOFTWARE - ViewSonic VX910 19” Color TFT LCD Display.

Model No.VS10162

UPGRADE PROCEDURE

After installation, shortcuts may be found in the settings path or the program menu (default setting). [See the previous post here, for more details]

* The security file is a key to use ISP functions; press the "OK" button.

* The warning shown is used to remind the user that a CPU rate that differs from IIC protocol may cause the ISP functions to fail; press the "OK" button.

* As shown in Fig, press the "Create Security File" button to key in a security code, and use the slider bar to adjust the speed of the IIC bus.

* Fig below shows the settings for the ISP softwares security code. It requires two command numbers, and the commands must be keyed in sequentially: 7C, 4C, 77. The command numbers and commands must be set by the user while coding. For more details, please refer to section 6 boot code of ISP.

Using ISP to program MCU

* As shown in Fig, select the MTV type first, load the binary or intel hex file to be programmed into the MCU, click "OK," then press the "RUN" button.

* If the user changes the MTV type, the file must be loaded again, as the previously loaded file will be cleared.

* CRC (cyclic redundancy check): the host can check the result in the CRC register instead of reading every byte in flash.

* The Check MCU CRC OK message indicates that the host has verified the programs CRC; see Fig.
