Hi all,
I'm trying to implement a development board for my ds89c450.
I implement the circuit in attach but I cannot connect my micro with the PC.
I got this message from MTK2: Unable to establish communication with target.
Check connection to target system or consult help files.
I´m already did everything that you talk in another posts in the forum, but nothing make this work.
I think that the problem could be because of the 0.1u capacitors in max232, but in datasheet, they talk about that possibility.All the capacitores in max232 are polyester ones. That could be another problem.
Can you help me?
Greetings
