#130808 - Real? Responding to: ???'s previous message |
Adrian Worley said:
Are the I/O lines providing/requiring 5V, or is that a real UART in there giving/wanting nominally 3.3V? What do you mean by "real" here? How do the voltage levels make a UART "real" or otherwise? Are you confusing "UART" with "RS232 Transceiver" or even "COM: Port"? |
