#65090 - RE: 8051/8255 interfacing Responding to: ???'s previous message |
can u suggest some way to increase the no i/o ports ....i mean any alternative to 8255. First suggestion: is it really so hard for you to type "you" properly? Please, stop this SMS nonsense - you're not on a mobile phone now! CPLDs have already been suggested. ST's PSDs are another: http://www.st.com/stonline/.../index.htm Maybe a Triscend E5: http://www.triscend.com/products/e5.htm or any of the many modern derivatives with loads of IO - see the 'Chips' link, or try the parametric search on Keil's device database: http://www.keil.com/dd/parm_search.asp Or an IO expander on I2C, Dallas 1-Wire, SPI, etc, etc,... |
