CC1200: CC1200

Arabella Zhang

Part Number: CC1200

Tool/software:

Dears,

The customer uses the CC1200 in the RTK receiver project. Now it is the sample stage, and 70 CC1200s have been pasted before.

1. Now it is being debugged and technical support is needed, mainly on the software, CC1200 chip, the customer did not find the complete register configuration of wireless transceiver on the official website, does the customer provide the register configuration to the customer?

2. The LoRa chip used by the customer before, and now needs to use the FSK modulation scheme, so CC1200 is chosen, should we have detailed application experience and cases can be provided?

Many thanks,

Arabella Zhang

Hi Arabella,

1. You can find it in the user's guide: https://www.ti.com/lit/swru346

2. You can find software examples here: https://www.ti.com/tool/download/swrc274

If you have a specific issue, you can post the details and I will try to help you solve it.

Cheers,

Marie H

Hi Marie H,

Thanks for your reply. Could you provide a demo code for receiving and sending with unlimited packet length?

(The length of bytes sent each time varies from 1 to 2000, depending on how much the MCU gives and how much the RF chip sends)

Thanks,

Arabella

Hi Arabella,

You can use variable packet length mode. From the User's Guide:

"When variable packet length mode is enabled (PKT_CFG0.LENGTH_CONFIG = 1), the first byte is the length byte. The packet handler stores this value as the packet length and receives the number of bytes indicated by the length byte. If fixed packet length mode is used (PKT_CFG0.LENGTH_CONFIG = 0), the packet handler will accept the number of bytes programmed through the PKT_LEN.PACKET_LENGHT register field."

Cheers,

Marie H

Dears,

When my customer used CC1200, after pulling the CSN level of CC1200 low, the MISO level was pulled high, which is contrary to the requirements of the manual. Please help analyze the reason? Blue is MISO, green is CSN. (The manual says that CSN is pulled low and MISO is pulled high)

Many thanks,

Arabella

Dears,

The customer wants a code that can directly call the interface to configure the frequency, power and baud rate, instead of through smartrf stdio 7.

In addition, a demo of sending and receiving in infinite packet mode is also needed. There is a requirement that the receiving end will judge the packet length of the whole packet based on the first few bytes received and decoded.

Could you please provide it?

Many thanks,

Arabella
