Disconnect the dc power adapter and the ribbon cable from the target board.


In the ‘Connect using: Additionally, Silicon Laboratories assumes c0851f340 responsibility for the functioning of undescribed features or parameters. CF” in the status bar of the IDE if the connection was successful.

Formatting using Windows Explorer: This shows a ‘Download’ dialog. The files created during the previous example application demonstration will be visible. You will see the text “Download successful” in the Build window if the firmware was downloaded successfully.

After the device has enumerated and shows up as a removable disk, open ‘My Computer’, right-click on the removable disk, and choose ‘Format’. Before connecting to the target device, several connection options may need to be set. See Figure 8 for the correct jumper settings. Click the ‘Download’ button to download this firmware to the ‘F device. Make sure that the jumpers on the ‘F TB are as shown in Figure 8. See Figures 11 and In this configuration, the embedded system is able to perform various tasks based on user commands via a UART-based interactive command shell.

This hardware and the included ‘F firmware fully demonstrate how an application can benefit from implementing the USB MSD device class. Optionally, you can enter a volume label as well. The ‘F ADC0 measures the temperature using the on-chip temperature sensor, which is then logged to a file. Follow the steps below and also refer to Figure Example Application – Temperature logging Rev.


Wait for a few seconds to collect some temperature data in the file. Type “log” to stop the log. In this case, the card should be formatted using a dedicated memory card reader or other specialized device. The commands are not case-sensitive. Files can be viewed, added, deleted, copied or moved using Windows C8051340.

Type any name for the new connection, and click OK.

Example Application – Button state logging 3. The board schematic is shown in Figure A command interpreter shell is presented via HyperTerminal. This is done as described in the following Microsoft Knowledge Base article: Long file names are not supported by the shell. Once these selections are made, click the OK button to close the window. There should be no need for any user interaction during this phase. A full version of the Keil tool chain is required in order to modify and recompile the code provided with this reference design because the code size is greater than evaluation tool chain’s code size limits.

If the memory card does not appear as a valid USB Mass Storage Device when connected, it is most likely formatted in a way that is not readable by the firmware for example, a custom digital camera format. First, select the adapter that was included with the kit in the “Serial Adapter” section.

Apply power to the target board using a dc power adapter. Silicon Laboratories reserves the right to make changes without further notice. This will not work properly if the existing file system is of a format other than FAT Depending on which type of debug adapter you have, set up the hardware as shown in one of the two diagrams below Figure 5, Figure 6. Insert the SD card provided with the reference design kit into the SD card slot M2 in the gb board.

Type “templog” to stop the log. The connected setup with a SD memory card is shown in Figure 2.

The development kit can be purchased separately from Silicon Laboratories www. Using the Format command will erase all data from the target disk, and is irreversible.
