Hi,

I'm working with the 6220, 6225 and the ST622X-kit. I now come to the point where the memory of 4k is too small for the application . I'm thinking of continuing the job in a 6 I'm aware of the need of another starterkitboard (ST623X-kit), which is no problem. The question is, can I use my old code with this other µC and is the assembler equal to the assembler that comes with the ST623X-kit? Is there anybody out there, who knows? Daan

Hi,

The ST6 core remains the same throughout the ST6 family. The peripherals may change slightly. The interrupt vectors also change - beware of this. Also, the peripheral registers may move around a little. You need to remember that you are moving into paged memory. Care is needed where interrupt handlers live and also care must be taken when moving (swapping) memory pages. The tools, either WGDB6 or RIDE can be used for both. Hope this helps. Simon
