#153654 - How to make a Port, an Output port (C8051F330) |
Hi.. I am using two microcontrollers in a project, one is AT89C51 and other is C8051F330. Both are communicating over parallel link, i.e. P1 of both are connected with eachother and two other pins are used as STROBE and ACK signals. The only problem is that C8051F330 P1 can't become an input port, but it can output data very easily. I've tried Push-Pull & Open-drain configurations. I am also moving 0xFF on P1 before reading it. But it always shows wrong data. What may be the problem? |
