#177962 - the lpc900 series have different port hardware Responding to: ???'s previous message |

With the [classic] 8052 the problem is the port pins cannot source enough current and the triac needs to be fed current in order to turn it on. I can only assume the lpc900 series have different port hardware that will source sufficient current Yes, they do - the LPC900 series ports can be configured as Push-Pull.
