The 128 Segment LCD on the CP240x LCD Development Board is a VIM-878 low voltage LCD.

An example driver for this LCD can be found in the CP240x Examples Folder.

CilabsMCUExamplesCP240xCP240x_LCD_Example

Earlier versions of the CP210x VCP driver purposefully did not allow the PC to enter standby mode when a handle to the CP210x was open.  If the PC attempted to enter standby while the handle to a CP210x was open, the following message was displayed:



The VCP driver did this to prevent any errors from occuring during the Standby process (blue screens). 

In order to place the PC into Standby when a CP210x was connected, the application had to close the handle to the CP210x.  The application did this after any long idle period (please see this article for information on using the built-in Windows Timers).

Newer versions of the driver provide the capability to enter the standby state.  You can download the latest drivers here: https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx and run the self extracting executable to install the drivers.

Are the oscillator products available in Tape & Reel?

• Yes, all oscillator products are available in Tape & Reel with an 8mm pitch and 16mm carrier tape width, as noted below for the CLCC package type.

·      Order quantities for tape and reel is 250pcs. Tape and reel orders must be in multiples of 250pcs.

• To specify Tape & Reel, please include the “R” suffix on the part number when you place your oscillator order.  Please refer to www.silabs.com/VCXOPartNumber for additional part number information.
• For example: The “R” at the end of the 530AA1000M00DGR part number specifies the Tape & Reel option.
• Tape & Reel specifications for all Silicon Laboratories products are available upon request from your local sales representative.  The relevant XO/VCXO packaging subsection is included below for convenience:

How can I connect a single-ended LVDS or CML output to an Si5326 family device?

Assuming that the clock signal has roughly 50% duty cycle, the following circuit can be used:

Assuming that the clock signal has roughly 50% duty cycle, the following circuit can be used:

There isn’t a built-in dialog option to do this in the Precision32 IDE. However, the pre-build steps dialog can be used to add this functionality.  Please note that the paths in these instructions are assuming SDK v1.1.1.  For other versions of the SDK, update the paths to reflect the appropriate version.

1. Navigate to CiLabsPrecision32_v1.1.1UtilitiesFlashProgrammer.
2. Copy the files in this directory to CiLabsPrecision32_v1.1.1IDEprecision32 in.  Click Yes or No if asked to overwrite existing files, as they should be the same versions.
3. Inside the Precision32 IDE, right-click on the project name and select Properties.
4. Expand C/C++ Build in the left-hand area and select the Settings subheading.
5. Click on the Build Steps tab in the right-hand side.
6. In the Pre-build steps area, add a call into the si32FlashUtility program. This should look like si32FlashUtility -e 2 -r 1 to erase the entire flash after first resetting the device.  See AN678 for a detailed description of all of the options available for this command-line programming utility: http://www.silabs.com/Support%20Documents/TechnicalDocs/AN678.pdf
7. Press OK.

From this point, pressing the Debug button in the Quickstart view will erase the device using the si32FlashUtility command-line programmer before downloading the file and initiating a debug session.

The device header file (e.g. CiLabs32bitsi32-1.1.0si32Halsim3u1xxsim3u1xx.h) provides a set of #defines for locating variables in retention RAM. All you need to do is prepend __SI32_RETENTION_REGION to the variable's declaration. Here is an example:

__SI32_RETENTION_REGION uint32_t myVariable;
