Talk:RPi GPIO Interface Circuits

Simple Diode Level converter --> Is the schematic backwards?
I kinda think has RxD & TxD transposed. The RxD on the ATMega should RECIEVE 3.3v OK, but, the RxD on the Raspberry pi needs the voltage drop from the diode.

Can someone confirm this? I'm a master of transposing these and making the same mistake myself, but... I'd appreciate the eyeballs. If someone can confirm what I see, I'll happily fix the file.

Thanks,
