Hi All, As I said I don't have the software skills to jump to a significantly different device.
Having had a better look at the F7 range it seems that to get more FLASH and RAM than the STM32F405VGT6 whilst keeping to the "small" 100 pin package only actually leaves three options, differing only by irrelevant peripherals. That makes the STM32F765VIT6 seem good, and it's about £11 vs £9 for the STM32F405VGT6. So far so good. Physical pin mapping is subtly incompatible, but that can be handled as I haven't built any hardware yet. How much difficulty should I expect getting the existing code to build for it? Of course I could just proceed with the F4 like the SM1000, and just accept that 700D may not end up being possible. Decisions. :-) Thanks Richard <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Mon, 4 Feb 2019 at 20:25, Richard <[email protected]> wrote: > Hi All, > > Understood about the future modes, I was hoping to support 700D (when > released) so perhaps switching processor is desirable.
