They are abbreviated to 8. CF” in the status bar of the IDE if the connection was successful.

d8051f340 Detailed setup instructions are shown below. Launch HyperTerminal from your Start Menu: If the disk is formatted with d8051f340 file system other than FAT16, or if you are not sure what file system is currently on the disk, you can perform a new format on the disk using the “Format” command available in Windows Explorer. This is to protect against simultaneous access of the file system by the PC and the example application.

See Figures 11 and Memory card sizes should be greater than 16 MB, up to a maximum of 4 GB.

Follow the steps below and also refer to Figure Before connecting to the target device, several connection options may need to be set.

This is done as described in the following Microsoft Knowledge Base article: Once these selections are made, click the OK button to close the window. The board schematic is shown in Figure The events are logged with the time value in milliseconds that shows the time since the last event.

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. Additionally, Silicon Laboratories assumes no responsibility for the functioning of undescribed features or parameters.

The logging is appended at the end of the specified file in the current directory. In this case, the card should be formatted using a dedicated memory card reader or other specialized device. Source code for all the other firmware blocks is also provided, but typically there is no need to customize these blocks.


There should be no need for any user interaction during this phase. R5 are optional R3 4k7 Figure This document is available at the following web page: The pin connections are shown in Table 1.


You will see t text “Target: Wait for a few seconds to collect some temperature data in the file. In addition to the above commands, c80511f340 can also try other commands supported by the command interpreter shell. The operating system will detect the new hardware, recognize it as a standard USB Mass Storage Device, and install appropriate drivers. Example Application – Temperature logging Rev. 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.

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.

Click the ‘Download’ button to download this firmware to the ‘F device.

At the end of this process, you will see three entries in Device Manager, and you should also see a Removable Disk in Windows Explorer. Disconnect the dc power adapter and the ribbon cable from the target board. The board hardware is described in sections 6, 7, and 8. The ‘F ADC0 measures the temperature using the on-chip temperature sensor, which is then logged to a file. Silicon Laboratories products are not designed, intended, or authorized for t in applications intended to support or sustain life, or c8051f30 any other application in which the failure of the Silicon Laboratories product could create a situation where personal injury or death may occur.


In the ‘Connect using: First, select the adapter that was included with the kit in the “Serial Adapter” section. Optionally, gb can enter a volume label as well.

Formatting using Windows Explorer: 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. Long file names are not supported by the shell.

There are three parts to this demonstration: After the device has enumerated and shows up as a removable disk, open ‘My Computer’, right-click on the removable disk, and choose ttb.

Insert the SD card provided with the reference design kit into the SD card slot M2 in the expansion board. Memory cards formatted with other file systems cannot be used with this firmware. This hardware and the included ‘F firmware fully demonstrate how an application can benefit from implementing the USB MSD device class.

The following are the requirements to use this Reference Design Kit as described in this User’s Guide. See Figure 8 for the correct jumper settings. The connected setup with a SD memory card is shown in Figure 2. You will see the text “Download successful” in the Build window if the firmware was downloaded successfully.


In this configuration, the embedded system is able to perform various tasks based on user commands via a UART-based interactive command shell. Type “templog” to stop the log. Type any name for the new connection, and click OK.

Use this to interact with the device firmware to record a temperature log. The commands are not case-sensitive. It’s a community-based project which helps to repair anything.
