New Ti board - no scale
#6
Hi ThLDQ,

Can you recall if it was the green wires that were connected to the data pins on your old PCB?

The labels on the Launchpad pcb you have are different to mine - do you recall if the bluetooth RX pin was connected to p1.1 or p1.2 on your old pcb?

If we assume it was p1.2 as you have it now then next I would try connecting:

  X data on p2.5 and X clock on p2.0

  Y data on p2.4 and Y clock on p2.1

Test again (make sure the scales are connected before applying the power to the Launchpad pcb).

I have built a mixed scale config using these pin configurations with the mixed scale firmware and it worked well, (it was using generic Chinese scales, not Shahe, but it proved to me the separate clock pins definitely work).

If this still does not work then it might be worth trying the v2.0 firmware from the iGaging section of the Downloads page (https://www.yuriystoys.com/p/downloads.html) as this is listed as compatible with some Shahe scales, (more info following some of the links on https://www.touchdro.com/downloads.html). Note: Keep using the separate clock pins with v2.0 as you will see in the note on the TouchDro page that it confirms there is no longer a clock signal on p1.7 with this version of firmware.

Hope this helps.
