#142032 - who is Mr. Ludd ? Responding to: ???'s previous message |
wait a minute I will buy some popcorn, I guess the thread becomes more & more funny but useless. Inside this forum flaming is more important then giving the right answer ;-))
Why not using the HW SPI? Are we talking about an AT89S52 ? in most cases the HW SPI is allready in use for serial programming. That will conflict many many times with additional HW. Especially a beginner to 8x51 micros will get stuck. However, you are a well exeperienced guy so why can't you concentrate on helping others to find a simple way first ? http://www.mikrocontroller.net/attachmen...ltplan.PNG Now I will be killed :-| the given link will show you the basic design of an ENC connected to an AVR. This should help you (BEN) to get an idea. Feel free to use the PINs you like to use. |

| yes, thats why Ben is still using an AT89S52 | 01/01/70 00:00 | |

| This shows you how to use the HW SPI | 01/01/70 00:00 | |
| have a look here | 01/01/70 00:00 | |
| Both of which do use the HW SPI! | 01/01/70 00:00 | |
