The guy from www.electrobee.com was so kind to offer me a GameIO card for review. So here it is.

The GameIO, previously called Xiltendo CPLD Starter, is a slot-2 device that adds I/O capabilities to your DS. In a way it is similair to DSerial. It should be fun for a lot of electronics projects.



GameIO contains a XC9572XL-VQ44 CPLD chip. The datasheet of this chip can be found on the manufacturers website (http://www.xilinx.com/) or here as a direct download.

According to the documentation a lot is possible with this device:
Features
• No programming cable needed – fully in-system reprogrammable
• 72 Macrocell CPLD supported by free development tools (Xilinx WebPack)
• 2 user extension slots with 6+7 User I/Os
• Ready to use hardware configurations
• Many hardware examples with full source code
• Open-source Software for the CPLD configuration

Hardware Configurations
• UART (IrDA support also possible)
• MIDI interface
• SPI Master
• I2C Master
• Onewire™ Master
• Cypress PSoC Programming interface
• MMC/SD/SDIO Interface
• NAND Flash Interface
• JTAG interface
• Timer for performance profiling
• Frequency meter
• Pulse counter
• PWM generator
• R/C Servo Interface
• GPIO Interface
• User defined Interface

So let's find out what this device is about.
