#125944 - Been there done that. EZ52 Responding to: ???'s previous message |
Hello Jeff,
I laid out a PCB for the EZ52 and built it a while back. The schematic in online at this address. http://members.aol.com/cpu8052/writer2.gif. I could post the PCB foil patterns. The software could be modified to handle a 8048 pretty easy. Transistor Q2 and Q4 are improperly designed in the original circuit. I wound up lowering the pull-up resistor in order to make them work. I would say replacing these with a 74LS06 would be a better circuit. Frieder Ferlemann suggestion seemed doable to using LINUX. I would suggest holding off until the original poster at least attempted to try this. Regards, Charles Bannister http://members.aol.com/cpu8052/writer2.gif  |
