Abstract: An electronic device (50) includes an infrared transceiver (510) having adjustable infrared signal intensity capability. The electronic device (50) commences to establish communications with a secondary device (420 and/or 430) at a first power level, if the communication link is not established, the electronic device (50) increases the IR power level and tries again to establish communications. In an alternate embodiment, the electronic device (50) includes a power level table which keeps the power level which has been established for each secondary device (420, 430) using the method described above. The electronic device (50) before communicating with each of the secondary devices determines the proper power level to use depending on the secondary device (420, 430) it wants to communicate with.

Abstract: A method and apparatus includes row-major memory mapping for a graphics memory (14) while providing data to a column-major display such as a pixel array (19). The transfer of data is provided from a row-major memory map to data formatted for refreshing a column-major display. The column-major pixel array (19) provides a display with energy saving benefits for illuminating the LEDs. A software developer can provide graphics data generated or transferred by a microcontroller (12) for storage in the row-major graphics memory (14). The embodiment supports the display features such as the grey-scale mode and bi-level mode.
