Starter USB Software
This simple software is designed to start you out with the basics. Once the firmware is loaded on the SerMod-56 USB Board it will toggle Ports B, and D every 2 seconds using the Timer 0 interrupt. In addition to blinking ports the starter software also has two vendor requests that switch Port A high and low. These standard vendor requests (VR_PORTA_HIGH=0xD0 and VR_PORTA_LOW=0xD1) can easily verify that your host software (software running on your PC) will execute code on the SerMod-56 USB Board. This software is written in the Keil uVision2 IDE and Cypress CY3684 EZ-USB Development Kit will need to be installed if you wish to change the Start USB Software. This software is a modification of the bulkloop example in the CY3684 Development Kit. Three stars (***) before every line of code indicate the modifications made to the Cypress bulkloop example.
