MAX vs. MAX — Parallax Forums

Hello all, just wanted to see if anyone else has experienced this or has any suggestions After constructing the cable and triple-checking all my connections, when I try to send data over the line, the computer is receiving inverted bits. Any advice or assistance would be appreciated.

Attached is a quick-and-dirty diagram of my connections. Can anyone see anything obviously wrong with this? Even if my connections are incorrect, I still can’t figure out why the chip doesn’t appear to be providing any negative voltages.

July datashert, In your case, in the figure you have shown you have put only one capacitor between supply and ground.

The circuit requires 4 more capacitors as shown in Figure 8 of the data sheet you have attached. The other capacitors are needed for internal negative voltage generation.

Take note of the polarity of the capacitors. Figure 8 refers to thenot the that I am using. Figure 11 indicates that the capacitors are integrated internally on the MAX In Figure 11, note that capacitor pins and negative voltage pins are connected.

Have you done the same? Wow, I can’t believe I missed that I’ve been staring at the datasheet for so long, I never actually noticed the connecting lines in amongst the jumble of pin numbers and labels.


I’ll give it a try and followup with my results.
