Okay, I've run into another problem with my new friend, the STP16DP05B1R 16-bit shift register.
I am following the ShiftOut tutorial, which tells me that for a sink driver such as the STP16DP05, I have to put the anodes of my LEDs to the common power line and connect the cathodes to the shift register outputs. I made sure to switch the line connecting the shift register board to the LED board from ground to positive. Everything seems to be plugged in properly. However, I am getting no response from the ShiftOut hello world.... :(
I have done a bit of sleuthing, and it would seem that the problem arises from the external resistor. I found a forum post here that says something to the effect of my problem:
Not the same board but similar concept. What does it mean to "connect between VDD and the I/O"? I know what VDD is and where it is on my chip, but which I/O is this person talking about? Does this mean that I need to resist all of my LEDs individually?
Thanks in advance for your help everyone.
My head hurts.
