Hello,

I'd like to communicate by serial data between Arduino Uno & PIC18F45K20.

I have seen about pic18f45k20:

TABLE 26-1: SUPPLY VOLTAGE, PIC18F2XK20/4XK20
D001 VDD Supply Voltage 1.8 — 3.6 V

and
TABLE 26-9: INPUT/OUTPUT CHARACTERISTICS, PIC18F2XK20/4XK20
D030 with TTL buffer VSS — 0.15 VDD V
D031 with Schmitt Trigger VSS — 0.2 VDD V



1 - Is it (0.15 * VDD) or (0.15 + VDD) ?

I configured Ardiono uno 2 & 3 pin to be serial with SoftwareSerial. Theses pins outputs seems to be at 5 V.

2 - Should I put an interface between the pins of the Arduino and those of the PIC18F and if so which ones?

Thanks

I ask only so that we don;t double-up on the same information.
