For quick proof of concept, I purchased 4x Eval-AD5242DBZ & SDP-B Controller Board, reworked and connected them to my existing PCA) while the USB side are all connected to my laptop. However, I just realized that I can open only 1 GUI per PC. Understand that there are 2 address bits for AD5242 which allow me to connect 4 of this ICs with single I2C control bus. However, in the GUI, it seems like I can only update the Instruction Byte & Data Byte, may I know how can I control the Slave Address Byte as well so that I can choose & program my target board accordingly one by one when I connected all the 4 EVA boards to my laptop? Thanks!
