Communicating with a TLC5947
Forgive me, I'm still fairly new to this hardware stuff.     The code examples I looked at weren't very obvious in their workings with regards to SPI or at least they...

Thanks for looking, I appreciate it.   I've had a good search over the last 36 hours, most code snippets are based on hardware but I have enough to go on now.    ...

I was getting a little excited there for a mo , but yes sadly Jim is correct it's SPI. That said you are also correct, the current board connects to the TLC's with ports that...

What is the effect of the associated input pin during startup, won't it sink the voltage thereby bringing the blank pin low and therefore making the TLC active?   regards...

The issue isn't so easy to resolve I fear.  As I understand from reading the data-sheet, on startup all ports are inputs.     The problem I'm trying to solve is...

Problems with 2 SPI Slaves
this is how it's setup   /Setup SS for MCP as output     DDRC |=  (1 << PIN_SSW);  I'll but some test code on the analyser...

hmm, I thought I was toggling high low as below   PORTC &= ~(1 << PIN_SSW); // Start transaction spiSendByte(0x00); // function...

Sweet, thank you.     That said I'm having a hard time understanding why setting an output pin to low would sink the line to 0v unless the effect is to ground it....
