I am trying to read load cell data from Sparkfun OpenScale serial output with Serial Receive block (from the Hardware Arduino support package). I have the default setting in the OpenScale and have calibrated it. I have connected Tx to Rx and Rx to Tx and serial data baud rate is set to 9600 in simulink. I get some data out from the Receive block but do not correlate to the raw value I see in the terminal window. The Port number I know (1) but there is Data type and Data length. I know that the data from one reading is 24 bit and the serial transmission type is suppose to be 8-N-1. Does this mean that I shall set Data type to uint8 and Data length 3? Those resulting three bytes I can not correlate to the raw value in the terminal window even if I flip around the order of the bytes. What information do I need to get about a serial output devise to be able to configure and understand the data output from Serial Receive block? Thanks, Per

Hello,
Please note that Sparkfun OpenScale is not a supported device for the Hardware Arduino support package. For the list of supported boards, you can refer to this page.
