Hello everyone. I have a question with using the TLC5940 LED driver with a Teensy 3.6 as outline here https://www.pjrc.com/teensy/td_libs_Tlc5940.html . On that page it says to use 5 volts on the VCC, DCPRG and BLANK pins with the BLANK pin having a 10k pullup resistor. My concern is the 5 volts on the BLANK pin as it's also connected to pin 4 on the Teesny. I know Teensy 3.6 is not 5 volt tolerant and so will this be an issue if 5 volts is supplied to the BLANK pin and also connected to the Teensy on pin 4? I think it should be fine because of the 10k resistor but I'm inexperienced and would like confirmation before I try it.
Alternatively should I just power everything with 3.3 volts since the TLC5940 has a range of 3 - 5.5volts for VCC?
