dspic debugger schematic
Alright, I decided to try the Schaer, but I had no 7407N's to use, so instead I'm using hex inverters as my buffer, then feeding the inverted signal into a multiplexer, then used a BASIC stamp to both control a transistor network from the op-amped signal, then the signals are connected to the PIC.
The BASIC Stamp could buffer the signals, then send to the microprocessor, but I'm pretty sure this isn't real level shifting, as the inverter seems to raise the voltage?
Any idea, or just wait for the buffers to come/build the eagle?
