BUF12800EVM Software Overview

Figure 15 shows an error that pops up if the computer cannot communicate with the EVM. If you receive

this error, first ensure that the USB cable is properly connected on both ends. This error can also occur if

you connect the USB cable before the USB DIG Platform power source. Another possible cause for this

error is a problem with the USB Human Interface Device Driver on the computer you are using. Make sure

that the device is recognized when the USB cable is plugged in; this action is indicated by a

Windows-generated confirmation sound.

6.2 Using the BUF12800 Software

6.2.1 I

C Address Selection

As mentioned previously (refer to Section 4.6), jumper JMP6 is used to set the I

C address pin of the

BUF12800. Figure 16 shows how the hardware and software must both be set to enable communication

between the BUF12800EVM and the software. Without jumper JMP6 and the software address button

configured correctly, the software cannot communicate with the BUF12800 device.
