Details
4A The format for writing data to the camera IC’s is as follows:
Send Data
02, 4A, [DataLenH] + 80, [DataLenL], [SLV], [START_H], [START_L], [END_H], [END_L],
[DATASTART], [DATASTART + 1], … , [DATAEND], [CHK], 03
[CHK] = Lower 8bits of
“4A + ([DataLenH] +80) + [DataLenL] + [SLV] + [START_H] + [START_L] +
[END_H] + [END_L] + [DATASTART] + [DATASTART + 1] + … + [DATAEND]”
Receive Data
02, 4A, [DataLenH], [DataLenL], [SLV], [START_H], [START_L], [END_H], [END_L],
[DATASTART], [DATASTART + 1], … , [DATAEND], [CHK], 03
[CHK] = Lower 8bits of
“4A + [DataLenH] + [DataLenL] + [SLV] + [START_H] + [START_L] + [END_H] +
[END_L] + [DATASTART] + [DATASTART + 1] + … + [DATAEND]”
*An example of the sending data to write 23 to address 10 of the IC (IC slave address is 20) is as
follows:
(02, 4A, 80, 06, 20, 00, 10, 00, 10, 23, 33, 03)
50 This command is for sending an OSCD (On Screen Character Display) command to the camera.
As stated above, when writing OSCD commands to the camera, 32 bytes is the maximum amount
of data that can be written to the camera, with one communication.
For additional information, please check section "OSCD Command".
In order to generate an OSCD, set the "Command" to a value of 50. Set OSCD command to Data,
set the number of byte of the OSCD command to Data Length.
* The format for sending a command to the camera to clear the display and then to generate
a display of [0123] on the 3rd row of the 1st column is as follows:
(02, 50, 80, 0A, 08, 92, 18, 38, DC, 10, 11, 12, 13, FF, E5, 03)
