Hello all
I'm trying to use 4 TLC5955 LED drivers in a project and cannot for the life of me get any outputs working. I've used a logic analyzer to ensure the data stream is correct and i suspect that my issue lies with the GSCLK line. I was hoping that someone on these forums has tinkered with this chip before and could potentially share some wisdom.
My basic program attempts to do the following:
initialize:
Send single control Bit
Send DC/MC/BC data (96 Bytes)
Pulse Latch
Turn on display:
send single control Bit
send GS data (96 Bytes)
Pulse Latch
I'm still a tad confused if I need to send the data twice before pulsing the latch to write to the chip. Any feedback is greatly appreciated.
