Change of MCU
Hello everybody. I want to know why the new version of openMV has a downgrade of MCU, changing a STM32F429 to a 407, like in the first version of the board.
Thanks.
Thanks.

No we're using the STM32F427.

Re: Change of MCU
Ok, I say that because this pdf say it:
https://github.com/openmv/openmv/blob/m ... penmv3.pdf
I want to make my own testing board, what is the exactly MCU that are using?

Re: Change of MCU
Sorry about that, the 407 and 427 are pin compatible so the same footprint was used. We are indeed using the STM32F427.seba.wetzel wrote:Ok, I say that because this pdf say it:

Re: Change of MCU
Sorry for all this, too many questions, but can i know why use a 427 instead of a 429? Price?
I'm Interested fully about this projects since I read it on hackaday page

Re: Change of MCU
The only difference between the 427 and the 429 is the LCD controller, which we don't need. At some point I made a camera with an STM32F429 and SDRAM, which was never produced I just kept it for reference.
The eagle files naming is confusing, I'll rename them later to OpenMV1 (407 we made a few prototypes) OpenMV2 (This is the KS cam, using 427) and OpenMV-SDR (429+SDRAM)

Hello, do you have the hex file or the compiled file for this?iabdalkader wrote: ↑Wed Oct 17, 2018 5:46 pmHi, we moved the design files here:

Re: Change of MCU
Do you mean the firmware ? No we never actually released any camera with SDR so we don't support it, the design files are there for reference.victagayun wrote: Hello, do you have the hex file or the compiled file for this?

Ohh. I thought you did initial testing for V2 on this board....iabdalkader wrote: ↑Fri Oct 19, 2018 2:31 pmDo you the firmware ? No we never actually released any camera with SDR so we don't support it, the design files are there for reference.

Re: Change of MCU
Hello, I have ordered 3pcs H7, but may take a while to arrive and nothing to play with. In the meantime, do you share codes and/or hex files of OpenMV-SDR (429+SDRAM) that I can burn and program into the board right away and test?iabdalkader wrote: ↑Sun Jul 26, 2015 6:08 pmThe only difference between the 427 and the 429 is the LCD controller, which we don't need.

Re: Change of MCU
Yes the firmware for that is long gone and none of the current features existed back then, plus your pin-out will probably be different. You can still find the old SDRAM driver in the source code if it helps.
