in our company, we use avalanche-oriented programming.

with 9 digits, I see the simplest solution to use the 8x double expander from Michrochip, MCP23016. You only have to use 8 of them, because you can't connect more of them to one I2C line. This means that the 9th digit will always use 2 bits from each expander with address 0 to 6. You will have two f...

the way I see it is that you connect 7 segments to one port and 7 segments to the other port. Or you use a double expander from Michrochip. You connect it via I2C. I can still think of multiplexing two groups of outputs, each with 7 segments. This will require an external multiplexer with 1x 7 input...

Hello,
I'm looking for some I2C simulator. I wouldn't be mad if he could also do SPI.
