10. 1 2 NETMF Porting vs Using There are two sides to working with NETMF porting it and using it For example writing a JAVA game on a cell phone is much easier than porting the JAVA virtual machine JVM to the phone The phone manufacturer did all the hard work of porting JAVA to their phone allowing the game programmers to use it with ease NETMF works the same way porting is not easy but using it is effortless NETMF can be split into two major components the core CLR and HAL Hardware Access Layer The core libraries are made so they are hardware independent Usually no modifications are needed on the core libraries A developer porting NETMF for a hardware platform will need to make the HAL to handle interfacing the hardware control to upper layers According to GHI s experience with NETMF porting it is not feasible to work on porting NETMEF to your new hardware in case you are targeting medium or low quantities annually less than 100 000 units A faster to market option is by using one of the available OEM modules chipsets These OEM devices have everything you need built in the hardware and software Rev 4 11 Page 4 of 36 www ghielectronics com GHI Electronics _LLC USBizi User Manual Introduction 1 3 GHI s NET Micro Framework Based Solutions With GHI Electronics you re getting an experienced partner that offers a wide range of NET Micro Framework hardware and software capabilities using the various drop in modu
