#164744 - Elimination Responding to: ???'s previous message |
Standard rule of elimination.
What happens if you connect VCC through a series resistor of 1k to the port pins of the processor? Will the processor fight with the signal? Have you checked how you initialize the port pins of the processor so they are not outputs, driven low? Have you checked the datasheet of the RF module, in case it requires a pull-up resistor on the signals? |

| Rx on processor is _input_ - but what about the RF output? | 01/01/70 00:00 | |
