#189536 - You *need* a proper external reset generator! Responding to: ???'s previous message |

What I meant was if I reset the uC externally then the thing starts working. By just powering the 2051 uC it does not work. Exactly! So what you need is a proper external reset generator to ensure that your chip gets a proper reset at power-up. Such a circuit need only be a single 3-pin device - looking just like a transistor. http://www.8052.com/faqs/119931 Andy Neil said:

I figured that out after posting in the Keil forum If you're going to post the same question on multiple forums, it behoves you to keep them all up-to-date... |
