EZConfig Array and Radio Patch files

Hi There!

Going to use SI4455 with PIC18F14K22. SPI is working fine.

PART_INFO response 0x11 0x44 0x55 0x00 0x00 0x0D 0x00 0x03

I will load EZConfig Array & Radio patch into SI4455 by SPI.

Please be so kind to tell me where I can find EZConfig Array & Radio patch hex data?

Thanks.

Hi TolicSKLW,

 

Your part is Si4455-B1A. This revision needs no patching.

You can find EZConfig Array in the config header and sample application that you configure and generate in the Wireless Development Suite for Si4455-B1A.

Re: EZConfig Array and Radio Patch files

Many Thanks for previous post. It was really helpful.

Now I obtained radio_config_Si4455.h file & new questions:

There are two groups of bytes:

RF_WRITE_TX_FIFO        114 bytes;

RF_WRITE_TX_FIFO_1    112 bytes.

Have I to:

Write API Command WRITE_TX_FIFO 0x66 following with 114 bytes obtaining CTS after each group of 8;

API Command NOP 0x00;

API Command WRITE_TX_FIFO_1 0x66  following with 112 bytes obtaining CTS after each group of 8.

Have i to fill insufficient 8 byte groups?

Thanks.

Re: EZConfig Array and Radio Patch files

There are no 8 byte groups in the WRITE_TX_FIFO command and need no obtaining CTS.

CTS is needed only after NOP.

Eight byte commands are in patch, not in the EZConfig array.
