Details
4A The format for reading data to the camera IC’s is as follows:
In the case of writing, since maximum number of addresses can be written at once is 32
addresses,
data must be written 8 times separately if 256 bytes data must be written.
[SLV]: Slave Address
(Please refer to the Slave address for the ICs (8 bits) list)
[START_H] x 16 + [START_L]: Star Address (0000 to 03FF)
[END_H] x 16 + [END_L]: End Address (0000 to 03FF)
[Data (i)]: Data on Address i
[DataLenH]: Upper Byte of
[END_H] x 16 + [END_L] - [START_H] x 16 + [START_L] + 6
[DataLenL]: Lower Byte of
[END_H] x 16 + [END_L] - [START_H] x 16 + [START_L] + 6
The format for reading data to the camera IC’s is as follows:
Send data
02, 4A, 00, 05, [SLV], [START_H], [START_L], [END_H], [END_L], [CHK], 03
[CHK] = Lower 8bits of
“4A + 00 + 05 + [SLV] + [START_H] + [START_L] + [END_H] + [END_L]”
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 sending a command to read out all data (address 0000 to 07FF) from the IC
(IC slave address is 50) is as follows:
(02, 4A, 00, 03, 50, 00, 00, 07, FF, A3, 03)
