Hi, everyone! I am developing a fruit-sorter, and this device was controlled by PC. Now, I want to design a microprocessor system to execute it. About hardware, I don't want to change too much, so there is a problem I need to work out--- How to implement communication between AD convertor and my microprocessor system ? Need what kind of technologies? What about hardware? software?
Use the Philips 80C552 or one of the new Cygnal 8051's. They have integrated ADC's. Very simple "communication".
The problem is that I must use this ADC. IF I use Philips 80C552 or one of the new Cygnal 8051's which have integrated ADC's, I must rework my sensor system, even I must change existing sensor. How do you think? Hope you could give me some detailed advice.
You will get a much more detailed reply if you tell what particular ADC you are using.
Thank you for reminding me. In fact, this ADC is specially designed(by third-party company)for my device, so I am not familiar with it. Now, I am assigned to improve this device. I need use a microprocessor system to replace PC. Thus, this device's price will become low. In order to implement comunication between microprocessor system and ADC, What should I know? Pls give some detailed advice or some examples.
If your ADC works with a PC, it probably has an ISA interface. I heard that ISA bus works very much like a simple microprocessor bus, so connecting it to a microcontroller should not be a problem. If it's PCI bus, you are in trouble, that's all I know. Actually, there is a chance that the third-party company which designed the ADC has some documentation on it. There could be a lot of useful information in it. Regards, Mike
