Multiplex Drive to an LED Matrix
do remember you must synchronize scroll with the MPX. you must synchronize intensity reulation with the MPX. you must synchronize text changes with the MPX. I did not check the price of these chips, but before you go on DO compare the price to non-MPX with e.g. ST2221A or ST2221C. Also are the chips referred to constant current drive or do you have to use series resistors which will give a more noticeable difference in intensity between the individual LEDs Erik MPX = multiplex |
