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