For a project I have a requirement to interface 12 nos of 4 digit seven segment display modules to one P89V51RD2. ....
I am basically looking for something like the SAA1064 where you can have four modules on to one I2C bus. Is there anyway to do what I want without resorting to multiprocessor communication ? You can easily run multiple i2c bus in SW on the P89V51RD2. Another popular part in Asia is TM1637 LED driver Search 4 Digit TM1637 LED on eBay for modules with LED+TM1637 (that also needs multiple i2c bus) |
