ASYNCH_TX_DIONUM
- Address: 5410
The DIO line that will transmit data. (TX)
  • Data type: UINT16  (type index = 0)
  • Readable and writable
  • Default value: 0
ASYNCH_RX_DIONUM
- Address: 5405
The DIO line that will receive data. (RX)
  • Data type: UINT16  (type index = 0)
  • Readable and writable
  • Default value: 0
ASYNCH_BAUD
- Address: 5420
The symbol rate that will be used for communication. 9600 is typical. Up to 38400 works, but heavily loads the T7's processor.
  • Data type: UINT32  (type index = 1)
  • Readable and writable
  • Default value: 0
ASYNCH_RX_BUFFER_SIZE_BYTES
- Address: 5430
Number of bytes to use for the receiving buffer. Max is 2048. 0 = 200
  • Data type: UINT16  (type index = 0)
  • Readable and writable
  • Default value: 0
ASYNCH_NUM_DATA_BITS
- Address: 5415
The number of data bits per frame. 0-8, 0=8.
  • Data type: UINT16  (type index = 0)
  • Readable and writable
  • Default value: 0
ASYNCH_NUM_STOP_BITS
- Address: 5455
The number of stop bits. Values: 0 = zero stop bits, 1 = one stop bit, 2 = two stop bits.
  • Data type: UINT16  (type index = 0)
  • Readable and writable
  • Default value: 0
ASYNCH_PARITY
- Address: 5460
Parity setting: 0=none, 1=odd, 2=even.
  • Data type: UINT16  (type index = 0)
  • Readable and writable
  • Default value: 0
ASYNCH_ENABLE
- Address: 5400
1 = Turn on Asynch. Configures timing hardware, DIO lines and allocates the receiving buffer.
  • Data type: UINT16  (type index = 0)
  • Readable and writable
  • Default value: 0
  • This register uses system RAM. The maximum RAM is 64KB. For more information, see 4.4 RAM
