= Welcome to Project Calypso =

This is the internal / confidential project page about our experiments with the Ti [wiki:Calypso]/[wiki:Iota]/[wiki:Rita] chipset

We originally intended to build an inexpensive GSM experimentation board built with/around that chipset, but right now
are pursuing a slightly alternative course by using cheap off-the-shelf feature phones and write custom software for it. * The [wiki:ProjectRationale] * The big [wiki:MasterPlan] * [wiki:AreasOfWork] -- What needs to be done and who wants to do it * Sub-Tasks and [wiki:AreasOfWork who is working on what] * Information about the [wiki:OpenmokoCalypsoModemDesign] * [wiki:Calypso] -- The HERCOM digital baseband chip (DSP+ARM7) * [wiki:CalypsoDSP] -- The DSP inside the Calypso DBB * [wiki:Iota] -- The TWL3025 analog baseband chip (ADC/DAC) * [wiki:Rita] -- The TRF6151C GSM transceiver (VCO, up/down-conversion) * Current plan/spec of the [wiki:GsmDevelBoard] (note: This project is on hold right now! * Notes on the [wiki:TSM30Layer1 TSM30 Layer1] as it can be found in the TSM30 source
