Connection from BBOUT to AD converter exists only for the purpose of estimating received signal strength, it has nothing to do with the high speed radio ability. The high speed radio stack was enabled through the use of SPI hardware to send and receive data bytes.

A new radio stack for the chipcon is under development. A new mica platform that has the chipcon is being considered by crossbow--they already have a mica "dot" platform that is the size of a quarter with an atmega128 and a chipcon radio. we have a proof of concept radio stack at this point in time but nothing sophisticated. a Berkeley grad student is working on a better one. the chipcon is nice, it allows frequency adjustment and provides a longer range. it also appears to be independent of operating voltage (2.0-3.3V) which the RFM is not (the reason that the boost converter is provided on the current mica) 2 and 3 are correct. 4 I'm not sure. 5 you'll need to ask Wei. -Joe -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Richard Wynn Sent: Sunday, October 13, 2002 7:31 AM To: [EMAIL PROTECTED] Subject: [Tinyos-users] A few radio review questions. Hello, 1) Has anyone tweaked the radio stack yet on the Mica platform to use the Chipcon CC1000 to lower the cost of COTS macro motes? Better performance, worse performance? As stable as the RFM TR1000? 2) Using the RFM TR1000, all motes up to the Mica were configured for OOK, correct? 3) The Mica's TR1000 is configured for ASK instead of OOK and added a line from the TR1000 BBOUT pin to the AD converter for hardware acceleration, correct? 4) The BBOUT pin to the AD converter, rather than the ASK configuration is what allows the use of the high_speed_radio_stack for Mica, correct? (Lazy me for not digging through the source code!) ;-) 5) Wei Ye's group developed their comm stack on an 8535 platform without the BBOUT line but their code supports the Mica platform... Is the BBOUT hardware acceleration supported or needed? Are the earlier Rene and Rene2 platforms supported? Thanks!
