#94029 - Getting this Atmel 89C51RD2 to work |
Hi,
For a small project I have set up a 89C61RD2 on veroboard and point-to-point board with a Max232. First off, I'm trying to get it into ISP. It's in a 64 pin PLCC socket. I have the following connections to the IC: Vcc -0v Vss -5v RST -10uF cap to Vcc RxD, TxD -Max232 XTAL1,XTAL2 -11.0592mhz osc. PSEN -0v !EA -5v I have 0.1uF greencap capacitors on the max232. Is this okay? It's not doing anything over serial. I'm using Atmels Flip software. I don't have immediate access to a scope but is there any way to find out if the chip is initializing? Are there any connections that I'm missing? Thanks Arron |
