In addition to the above commands, you can also try other commands supported by the command interpreter shell. This is an example of asynchronous logging, where the interval between logs is not known in advance. If the disk is formatted with a file system other than FAT16, or if you are not sure what c80051f340 system is currently on the disk, you can perform a new format on rb disk using the “Format” command available in Windows Explorer.

Specific Hardware’ all shown in blue in Figure 3. Interacting with the Example Application 1. 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. Type “log” to stop the log.

Silicon Laboratories makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does Silicon Laboratories assume any liability arising out of the application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation consequential or incidental damages.



The operating system will detect the new hardware, recognize it as a standard USB Mass Storage Device, and install appropriate c051f340. This is done as described in the following Microsoft Knowledge Base article: Using the Format command will erase all data from the target disk, and is irreversible.

c8051d340 Make sure that the jumpers on the ‘F TB are as shown in Figure 8. It’s a community-based project which helps to repair anything. Additionally, Silicon Laboratories assumes no responsibility for the functioning of undescribed features or parameters.

The files created during the previous example application demonstration will be visible. The connected setup with a SD memory card is shown in Figure 2. There should be no need for any user interaction during this phase. This is an example of periodic logging, where the interval between logs is known in advance. Should Buyer purchase or use Silicon Laboratories products for any such unintended or unauthorized application, Buyer shall indemnify and hold Silicon Laboratories harmless against all claims and damages.

Use this to interact with the device firmware to record a temperature log. The development kit can be purchased separately from Silicon Laboratories www.


In this configuration, the embedded system is able to perform various tasks based on user commands via a UART-based interactive command shell.

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. Source code for all the other firmware blocks is also provided, but typically there is no need to customize these blocks.

See Figures 11 and The logging is appended at the end of the specified file in the current directory. Follow the steps below referring to screenshot in Figure 9. The ‘F ADC0 measures the temperature using the on-chip temperature sensor, which is then logged to a file.

Apply power to the target board using a dc power adapter. R5 are optional R3 4k7 Figure A command interpreter shell is presented via HyperTerminal. This hardware and the included ‘F firmware fully demonstrate how an application can benefit from implementing the USB MSD device class.

Formatting using Windows Explorer: Disconnect the dc power adapter and the ribbon cable from the target board. Type any name for the new connection, and click OK.
