Hi
Can anyone tell me if a bootloader is required for the QB8 ic (V4 unit) as was the case with the KX8 based V3 unit.
I have some brand new ic's that I want to experiment with but can only see the 4.0.2.s19 file in the downloads section and no related bootloader. I am assuming it is incorporated into the main s19 file.

I assume its a yes /no answer to this one.

cheers

Yes and maybe!

The bootloader is required - it's the bit of code that the PC communicates with via RS-232 to download the .s19 file.

The bootloader might be in the .s19 file.

AFAIK the bootloader isn't downloadable from this site, but I suspect it is a standard one available elsewhere. You also, of course, need a method of getting the .s19 (with teh bootloader in it), or the bootloader by itself, into your blank chips, which will need a programmer of some sort...

...but I'm an Atmel AVR man, so I don't know the specifics. In my AVR apps, the bootloader is in the hex file itself (so it can update itself), but I have to put the initial hex into the AVR with a programmer

HTH...
