New product - USB-SPI Interface Adapter SPI-10
USB-IO Interface Adapter GPIO-24. Programmers Reference Manual.
| Byte 0 | Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6 | Byte 7 |
|---|---|---|---|---|---|---|---|
| GPIO_SET_ HPWM_ CFG (0x14) | ECHO | HPWM_ NUMBER | ON | TL | TH | T1L | T1H |
PWM mode is configured specifying the high time (T1) and period (T) in µs. These values can vary from 1 µs to 340 µs.
Command is an 8-byte array of the following format:
- Byte 0: GPIO_SET_HPWM_CFG (0x14)
- This byte contains command identifier (command type). It should be set to 0x14.
- Byte 1: ECHO
- This byte can be used to associate a response received from GPIO-24 adapter with specific command. Response will contain exactly the same value in its echo byte.
- Byte 2: HPWM_NUMBER
0 – A.5;
1 – B.5.
- Byte 3: ON
1 – enable HPWM on HPWM_NUMBER pin;
0 – disable PWM on PWM_NUMBER pin.
- Byte 4: TL
Least significant byte (low byte) of period in µs.
- Byte 5: TH
Most significant byte (high byte) of period in µs.
- Byte 6: T1L
Least significant byte (low byte) of high time in µs.
- Byte 7: T1H
Most significant byte (high byte) of high time in µs.
