#81638 - AT89S52 with I2C and SPI. Responding to: ???'s previous message |
Hi Nguyen,
AT89S52 has an Hardware SPI engine in it. Thus you can interface SPI devices with it very easily. Although AT89S52 doesn't have a Hardware I2C in it but you can use software routines to bitbang I2C. For these routines check out this link by Peter Dennegar. http://www.specs.de/~danni/appl/hard/i2c/ If you need a micro with hardware I2C search the keil device database with required features. http://www.keil.com/dd Regards, Prahlad Purohit |
