5) Press the Send Now button to write the data to the
MAX6952 EV kit. For example, to set the MAX6952
EV kit’s display intensity to 2/16 for digits 1, 2, 5, and
6, enter the command word 0x01 and data word
0x11 as: 0x01,0x11, 0x01,0x11 and click the Send
Now button. Multiple commands and data sets must
be sent to the EV kit since two MAX6952 ICs are
serially cascaded. Setting the repeat to 2 automati-
cally accomplishes this. Data received from the
MAX6952 ICs is displayed under the Data Bytes
received.
