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 software's 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 program's CRC; see Fig.
