Custom ASCII Read/Write Examples
Example Description
SR$ Read display value from all controllers, 50ms delay.
S15R$ Read display value from controller address 15, 50ms delay.
S3U40* Read unformatted data in channel 4 from controller address 3, 2ms delay.
S2W2 –10000$
Write
–
10000 to the display register of controller address 2, 50ms delay.
SWT CHAN_1$ Write ASCII text string Chan_1 to channel 1 text register, 50ms delay.
Controller Response - After the controller has completed a read or write instruction,
it responds by sending a carriage return/line feed (CR/LF) back to the host. If
the instruction was a read command, the CR/LF follows the last character in the
ASCII string. If it was a write command, CR/LF is the only response sent back.
The host must wait for this before sending further commands to the controller.
If the controller encounters an error, it will respond with a null (0x00) CR/LF.
