MISO/MOSI incorrect.

[AtomSoftTech]

You have this: SDO, MISO SDI, MOSI

When its actually supposed to be: SDO, MOSI SDI, MISO

Thanks for pointing this out Jason. It is now fixed.

Microcip uses SDO as SPI out of any chip, so sometimes SDO is MISO and other times is MOSI. The same is true of SDI for input. This statement is made from my failing memory but I am pretty sure it is correct.

I understand but that depends who is the MASTER in this case. Since the Fubarino is the master (in most cases)

MISO = Master In Slave Out MOSI = Master Out Slave In

SDO = Serial Data Out SDI = Serial Data In

So SDO = MISO can only be correct if Fubarino is slave

Jason,

Thanks for clearing that up for me.

Consider this, since an SPI bus is not multi master like I2C but dose support multipul slaves this means there will in all cases be at least an equal number of master and slaves. But should there exist any systems that have more than one slave then slave devices will out number masters.

But yes, I agree the Fubarino will probably be the master in most cases since most slaves will be some kind of peripheral device.

P.S. I checked your web page, nice work with the Fubarino. On Aug 17, 2014 5:35 AM, "Jason Lopez" notifications@github.com wrote:

Heh yeah. And thanks. Ive made a few fubarino style clones also but havent documented them since they are for other clients. They use basic hardware but no bootloader. Fubarino saved me weeks of studying.

Its an awesome device. When does this newer fubarino come out? Im so anxious! The SDZ...

Since the documentation is now fixed, I believe, I'm going to close this issue.
