35 / 67 page ![]() WI.232FHSS-25-R/ WI.232FHSS-250-R DATASHEET 34 Revision 1.1.0 4. Module Configuration The Wi.232FHSS modules will work right “out of the box” without any configuration. However, a great many configuration registers are exposed to allow for the custom-tailoring of the wireless link. These registers are classified as four different types: non-volatile R/W, non-volatile R/O, volatile R/W, and volatile R/O. During the power-on/reset sequence, the non-volatile read/write registers are copied into the volatile read/write registers. This allows the integrator to determine a default configuration for the wireless link that can be preset at the factory, requiring no intervention by the host processor. During operation, changes to the volatile read/write registers have an immediate effect on the Wi.232FHSS parameters. Non-volatile read-only registers provide a way for the host application to retrieve information about the module hardware, firmware, and hard-coded configuration parameters such as the MyGUID address. 4.1. Register Descriptions 4.1.1. CRC Error Count (regCRCERRCOUNT) regCRCERRCOUNT (0x40) R/W R/W R/W R/W R/W R/W R/W R/W B7 B6 B5 B4 B3 B2 B1 B0 7 6 5 4 3 2 1 0 The value in this register is augmented each time a packet is received that fails CRC check. Writing 0x00 to this register will initialize the count. 4.1.2. Channel Hop Table (regHOPTABLE) regNVHOPTABLE (0x00) regHOPTABLE (0x4B) R/W R/W R/W R/W R/W R/W R/W R/W RES D6 D5 D4 D3 D2 D1 D0 7 6 5 4 3 2 1 0 Default hop sequence: 0 The Wi.232FHSS supports 6 different hop sequences with minimal correlation. Changing the hop sequence changes the physical band utilization, much the same way that a channel does in a static transmitter. Valid values are 0-5. Chapter 4 |
