C code that can run on an Texas Instruments EZ430-Chronos 433MHz watch [1] with a software module that implements interfacing with intertechno radio switches forked from: http://openchronos-ng.sourceforge.net new module: https://github.com/rodan/openchronos-rfsw author: Petre Rodan <2b4eda@subdimension.ro> license: GNU GPLv3 Based on a nice tutorial by Christian M. Schmid http://blog.chschmid.com/?page_id=193 Requirements: msp430 toolchain python-2.7 Usage: Line1 contains FF.DD FF is the decimal notation of the family in which the device is placed [1-16] A is 01, B is 02 ... P is 16. this option must be used for doorbell/PIR device selection DD is the decimal notation of the device number [1-16] on some factory remotes devices are placed in 4 groups, in this case device 2 from group 3 is device number 10. special devices like doorbell/PIRs must be set as device number 8. Line2 becomes 'on', 'off', 'spe' depending on what command was sent last if compile time option CONFIG_MOD_INTERTECHNO_PW is set then the output power is selectable on Line2. radio glyphs come up when the command is sent. buttons: up - send an 'on' command to the current device down - send an 'off' command # - send a special command (for doorbells/PIRs), make sure DD is 8 in this case. long * - enter config mode. use up, down, # to select family and device, * to save.
