extends SerialComVendorLib

Silicon labs provides libraries to communicate with their USB-UART devices. More information can be found here : https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

• The data types used in java layer may be bigger in size than the native layer. For example; if native function returns 16 bit signed integer, than java method will return 32 bit integer. This is done to make sure that no data loss occur. This library take care of sign and their applicability internally.

• Developers are requested to check with vendor library documentation if a particular function is supported for desired platform or not and also how does a particular API will behave. Also consider paying attention to valid values and range when passing arguments to a method.

• The application note for CP210XRuntime library is here : https://www.silabs.com/Support%20Documents/TechnicalDocs/an223.pdf

• SerialPundit version 1.0.4 is linked to v3.4.0.0 version of CP210xRuntime library (CP210xRuntime.dll).
