#170455 - P0.6 & P0.7 for UART-1 Responding to: ???'s previous message |
Dear Per,
It wont be P0.4 & P0.5 (I think that is what you mean by pin 4 & 5). As per the datasheet: 1> UART-0 gets P0.0 & P0.1. 2> Then comes SPI, it will use up 4 pins (P0.2, P0.3, P0.4 & P0.5). 3> Then Comes I2C, it will not useup any pin as not activated. 4> Hence now UART-1 will get P0.6 & P0.7 Also want to ask sarita, if she has configured it correctly (Open Drain or Push Pull).
