... Preliminary Technical Data HARDWARE CONFIGURATION FOR Blackfin BOARD The jumpers on the shipped Blackfin board are in the correct position for operation in the evaluation setup. Note that these are different than the default positions listed in the ADSP-BF537 EZ-KIT Lite Evaluation System how each of the switches (SW1 to SW8) should be configured for operation in the AD7764/AD7765 evaluation kit setup. The shaded boxes demonstrate where the slider switches should be in relation to the numbers on the switches ...
