USB-I/O Interface Adapter GPIO-24. Programmer's Reference Manual.
11.8. GPIO_SUSPEND_PLS_CNT (0x2B)
The GPIO_RESUME_PLS_CNT command resumes suspended pulse counter. This command can resume time counting and/or pulse counting.
GPIO_RESUME_PLS_CNT Command
| Byte 0 | GPIO_RESUME_PLS_CNT | Command ID |
| Byte 1 | ECHO | Echo to associate the command with the response |
| Byte 2 | PLS_CNT_NUMBER | ID number of the pulse counter to be resumed |
| Byte 3 | RESET_TIMER | Byte to reset time count |
| Byte 4 | RESET_COUNTER | Byte to reset pulse count |
| Bytes 5..7 | Reserved | Reserved |
Command is an 8-byte array of the following format:
- Byte 0: GPIO_RESUME_PLS_CNT (0x2A)
This byte contains command ID (command type). It must be set to 0x2A.
- Byte 1: ECHO
This byte can be used to associate a response received from GPIO-24 adapter with a specific command. Response will contain exactly the same value in its echo byte.
- Byte 2: PLS_CNT_NUMBER
The ID number of the pulse counter:
0 – pulse counter on A.3 pin;
1 – pulse counter on A.4 pin.
- Byte 3: RESET_TIMER
This byte resets time count:
1 – time count will start from 0;
0 – time count will start from suspended value.
- Byte 4: RESET_COUNTER
This byte resets pulse count:
1 – pulse count will start from 0;
0 – pulse count will start from suspended value,
- Bytes 5..7: Reserved
These bytes are reserved for future usage and must be set to 0.
For convenience GPIO_RESUME_PLS_CNT_CMD structure is declared in reports.h file.
GPIO-24 adapter sends GPIO_RESUME_PLS_CNT response after command execution.
GPIO_RESUME_PLS_CNT Response
| Byte 0 | GPIO_RESUME_PLS_CNT | Response ID |
| Byte 1 | ECHO | Echo to associate the command with the response |
| Byte 2 | ST | Command execution status |
| Bytes 3..7 | Reserved | Reserved |
Response is an 8-byte array of the following format:
- Byte 0: GPIO_RESUME_PLS_CNT (0x2A)
Response ID (response type). This byte will contain 0x2A.
- Byte 1: ECHO
Echo byte copied from the corresponding command. It can be used to associate the response with the specific command.
- Byte 2: ST
Status of the command execution:
GPIO_ST_SUCCESS (0x00) – Pulse counter has succesfully been resumed;
GPIO_ST_INVALID_PLS_CNT_NUMBER (0x0A) – Invalid ID of the pulse counter has been specified (only 0 and 1 values are valid);
GPIO_ST_INVALID_PARAMETER (0x0B) – Invalid reset timer parameter or reset counter parameter has been specified (only 0 and 1 values are valid).
- Bytes 3..7: Reserved
These bytes are reserved for future usage.
For convenience GPIO_RESUME_PLS_CNT_RSP structure is declared in reports.h file.
