coolSAA1064 | coolSAA1064 arduino library handles the 7 segment Philips

coolSAA1064 is a C++ library. coolSAA1064 has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The coolSAA1064 arduino library handles the 7 segment Philips / NXP SAA1064 driver. The Philips / NXP SAA1064 drives up to four 7 segment displays via an i2c communication. The 7 segments have to have a common anode, otherswise you have to use a lot transistors. Anyway the huge advantage of the SAA1064 is, that it deals with up to 18 V of VCC, still driving a 5 V (max. 5.9 V) level on i2c wires. That allows for driving large 7 segments, that are internally built by four to six LED diodes, and need an break through voltage of about 8 V to 12 V. Top of the line, the SAA1064 can control the current of the segments, and makes diming possible.
