SLAU292G November 2009 – July 2015
This mode requires the eZ430-Chronos Control Center PC software.
Press # until the "rFbSL" is shown (see Figure 3-1). This mode allows updating the firmware of the eZ430-Chronos module wirelessly.
Secondary function: Start or restart the update process. Push DOWN once to switch to the confirmation menu "CONF". Pushing DOWN again starts or restarts the update process (the wireless update on the PC must be started from the eZ430-Chronos Control Center first (see Section 3.3.1)). At the beginning of the update the LCD shows "rAM" for a few seconds. During this time, the update software is downloaded from the PC to the RAM of the CC430 on the Chronos module. This program contains all memory write and LCD routines. After this transfer is finished, the code is executed from RAM, and the download of the actual firmware file is started. The LCD shows the progress in percent on the upper LCD line. After the transfer is complete, a reset starts the software on the Chronos module. See Section 3.6.3 for details.
NOTE
When the wireless update is activated on the Chronos module, it returns to the main application only with a reset, whether or not an update was performed. Time, data, alarm, and other RAM-based data are lost.
