Good afternoon! I have a curious question. Wondering if you have a simple explanation for this, even if it is not critical. We have programmed the CAPTIVATE-FR2633 board. I have a simple SELF capacitance proximity attached to CAP0.0. Everything works fine :) I completely remove the jumpers in J3. Then I put my multimeter across J7 and install some batteries in "-" "+" external power pads. So, our board is floating, we have NOTHING connected (CAPTIVATE-PGMR board) to J2. Our code has been tested and it works, in fact LED2 flashes if we do not remove the jumper, which we do. The board consumes around 30 uA. However, if I remove the jumper in TX.0 (P1.4), the board consumes around 5 uA. Do you have any idea why? Looking at the schematic this does not make sense to me. On the other hand, when floating, I have some false proximity positives when placing my hands nearby the CAPTIVATE-FR2633 or the wire which connects the electrode. I expected the latter but not the former effect. Anyway, can you indicate, if any, some hint to shield the wire from the electrode to the CAPTIVATE-FR2633? Is there any way to avoid the rest of false positives when waving the hand over the CAPTIVATE-FR2633 board? :) Have a really nice day.
