CC1120 Transceiver Development #13

Open lambertjacob opened 2 years ago

lambertjacob commented 2 years ago

Motivation ⛰️

On the COMMS PCB we will be using CC1120 transceivers, so this project will involve configuring the transceivers so that we can communicate with the satellite.

Next Steps 🚶

[ ] Write / Find software that we can use to command the CC1120 with STM32

Supporting Material and Resources 📖

https://www.ti.com/tool/SMARTRFTRXEBK <-- looks like the evaluation board we have https://www.ti.com/tool/CC1120EMK-868-915 <-- the evaluation daughter board that is currently on them (868-915MHz) https://www.ti.com/lit/ml/swru290b/swru290b.pdf?ts=1664037182077&ref_url=https%253A%252F%252Fwww.google.com%252F <-- Quick start guide for the evaluation board kits https://www.ti.com/lit/ug/swru295e/swru295e.pdf?ts=1664038107963&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FCC1120 <-- CC1120 User guid seems helpful

The satellite will be uplinking at 144MHz.
The satellite will be downlinking at 433MHz.
The data rate must be 9600 bps [required by CSDC]
The link budget is can be found by following this path in the satellite-general files
- Satellite General > csdc > 3000-subsystem-budgets

Definition of Done 💯

This project will be marked as done once we have successful communication between two cc1120 transceivers. The testing can be done with cc1120 development kits.

hey @Steve-007, have you had a chance to work the cc1120s at all?
