The commands are not case-sensitive. 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 c80551f340.
If the disk is formatted with a 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.
See Figures 11 and Next, the correct “Debug Interface” must be selected. 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.
Before connecting to the target device, several connection options may need to be set. Example Application – Button state logging 3. Silicon Laboratories assumes no responsibility for errors and omissions, and disclaims responsibility for any consequences resulting from the use of information included herein. Memory cards formatted with other file systems cannot be used with this firmware.
Make sure that the jumpers on the ‘F TB are as shown in Figure 8. CF” in the status bar of the IDE if the connection was successful.
Specific Hardware’ all shown in blue in Figure 3.
The board schematic is shown in Figure Formatting using Windows Explorer: Launch HyperTerminal from your Start Menu: The following are the requirements to use this Reference Design Kit as described in this User’s Guide. 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.
If two files named ‘abcdefghi. Memory card sizes should be greater than 16 C8051f3440, up to a maximum of 4 GB. This document is available at the following web page: Long file names are not supported by the shell.
Follow the steps below referring to screenshot in Figure 9. The events are logged with the time value in milliseconds that shows the time since the last event. This is an example of periodic logging, where the interval between logs is known in advance. A command interpreter shell is presented via HyperTerminal. Type “templog” to stop the log. Press buttons labeled “P2. There should be no need for any user interaction during this phase. In the ‘Connect using: Follow the steps below and also refer to Figure Use this to interact with the device firmware to record a temperature log.
Silicon Laboratories reserves c8051g340 right to make changes without further notice. This is an example of asynchronous logging, where the interval between logs is not known in advance.
R5 are optional R3 4k7 Figure In this configuration, the embedded system is able to perform various tasks based on user commands via a UART-based interactive command shell. Other products or brandnames mentioned herein are trademarks or tv trademarks of their respective holders. DIR Show the contents of the current directory. Detailed setup instructions are shown below.
They are abbreviated to 8.
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. There are three parts to this demonstration: This will not work properly if the existing file system is of a format other than FAT Files can be viewed, added, deleted, copied or moved using Windows Explorer.
The logging is appended at the end of the specified file in the current directory. 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. You will see the text “Target: Once these selections are made, click the OK button to close the window.
The pin connections are shown in Table 1. Type “log” to stop the log. After the device has enumerated and shows up as a removable disk, open ‘My Computer’, right-click on the removable disk, and choose ‘Format’. Using the Format command will erase all data from the target disk, and is irreversible.
This hardware and the included ‘F firmware fully demonstrate how an application can benefit from implementing the USB MSD device class.
