CC1100/CC2500 Recent Updates
The CCxx00 radio stack is getting some new architecture. The last stable working version may be checked out from CVS using a special update by date, on or before January 20, 2008.
January 22, 2008
Status
- NON-OPERATIONAL: In a state of flux, dividing the prototype Blaze radio stack (blazeradio) into a new ccxx00 directory which will contain the final CCxx00 radio stack architecture.
Updates
- Updated all .platform files to point to the new ccxx00 directory
- Created a SplitControlManager component to reside just underneath the RadioSelect module.
- Isolation unit tested the SplitControlManager. All tests pass.
- Removed SplitControl functionality from RadioSelect module. The RadioSelect module is now entirely responsible for converting the non-parameterized Send and Receive interfaces it provides into parameterized Send and Receive interfaces it uses.
Tests
- Isolation test created for SplitControlManager in a new blaze/tos/chips/ccxx00/ directory in TUnit: blaze/tos/chips/ccxx00/isolation/SplitControlManager.

Status
- NON-OPERATIONAL: implementing better SplitControl architecture.
Updates
- Reduced the number of SPI register burst init elements from 39 to 25, decreasing the time it takes for init.
- Added the RadioReset interface and HplRadioResetC/P modules to allow the driver to check the SO line to see that the radio has been automatically powered up on reset.
- Removed RfResource and PriorityQueue from the radio stack.
- Removed while-loop hack functionality in BlazeInitP - this still needs to be tested with various hardware
Tests
- Created AutomaticPor test to test the RadioReset interface, which I have implemented for the MSP430-based platforms
January 20, 2008
Status
- OPERATIONAL. Stable on the MSP430. Full of hacks to try to get the hardware working. The radio typically refuses to go into TX mode on Atmega128 platforms.
