Draft
The value in the OpCode portion of the FTF field defines the function of the binary com-
mand, that is, whether it is a read command or a write command. The following
OpCodes are available:
The BCC-Code portion of the FTF field indicates the presence of a Block Check
Character (BCC). (The use of a BCC is optional.)
The AddrLen portion of the FTF field indicates the size of the command and status
register (CSR) address to which the command is being sent.
On
L800
k
cameras, all CSR addresses are 16 bits.
Example of an FTF field:
Assume that you are issuing a write command, that you are using a BCC and that the
CSR address you are writing to is a 16 bit address. In this case, the OpCode bits would
be 0b00000, the BCC-Code bit would be 0b1 and the AddrLen bits would be 0b00. This
would result in a binary value of 0b00000100, which translates to a hex value of 0x04
for the FTF field.
OpCode Function
0b00000 This is a write command used to write a single setting to the camera.
0b00001 This is a read command used to read a single setting from the camera.
0b00010 This is a read response frame without an address field.
(The AddrLen bits are ’don’t care’).
0b00100 This is a bulk write command used to upload a file into the camera.
0b00101 This is a bulk read command used to download a file from the camera.
0x00110 This is a bulk read response frame without an address field.
(The AddrLen bits are ’don’t care’)
BCC-Code Function
0b0 This frame (and also the response frame) contains no BCC field.
0b1 This frame (and also the response frame) contains a BCC field.
AddrLen Length of the Address Field
0b00 16 bits (= 2 bytes)
0b01 32 bits (= 4 bytes)
0b10 48 bits (= 6 bytes)
0b11 64 bits (= 8 bytes)
