Bääääär Posted October 16, 2010 Report Share Posted October 16, 2010 Hello MIDIBox-community! For a huge project I need USB and CAN in parallel - the Core32 board doesn't support this atm. That's why I looked for an alternative chip to use instead of the STM32F103RE and found this one with less memory (256kB - that's ok for me) but 2xCAN and even Ethernet on-chip: STM32F107RC. STM promises their portfolio of MCUs to make switching form one to another very easy (full pin compatibility and so on). So I really started thinking about adapting the MIOS for this MCU. But, well, I didn't really work with the MIOS so far (although I read a lot about it). I would buy a core32 and start testing, but well - it doesn't fit my needs and buying it only for the first steps with MIOS seems to be a bit senseless to me. So before buying things, witch I might never need, I'd like to check if it's possible, to adapt MIOS for my needs and probably build my own core32 with this MCU. Quite a long story for a simple question: How much effort would it make to adapt MIOS for this kind of MCU? Is anyone also interested in doing this? Thanks, Bääääär PS: I know that a new core32 is planned to solve the flaws of the "old" core32 (USB/CAN) but as far a I know, TK is waiting for a new chip with at least 512kB and the connectivity-options that the STM32F107RC is already supporting at 256kB. But it seems like STM will need some time until this new chip is released. Quote Link to comment Share on other sites More sharing options...
TK. Posted October 16, 2010 Report Share Posted October 16, 2010 I already ported MIOS32 to STM32F105RC, see also this posting: Adapting the new USB OTG module was a challenge, but I made it. STM32F107RC has the same USB peripheral, so that no additional MIOS32 adaptions are required. You could even compile the code for STM32F105RC, and it will work on a STM32F107RC as well. Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Bääääär Posted October 16, 2010 Author Report Share Posted October 16, 2010 Wow, that's good news! Thanks,! Looks like I'll definitly build a core32 with the STM32F107RC or the STM32F105RC then.
