#190564 - One 89V51RD2 and 12 nos 4 digit LED modules |
For a project I have a requirement to interface 12 nos of 4 digit seven segment display modules to one P89V51RD2. Even though the count of display modules are high the MCU most of time will be waiting for a proximity signal and once received update some data into the displays and then wait.
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 ? ( One central master MCU and 12 slave display modules with its own MCU ) |

| Why not many MAX7219 drivers? | Raghunathan | 09/09/15 04:44 |
| Sure, if you already have 12 x MAX7219 | Jim Granville | 09/10/15 20:24 |
