Is it necessary to have FRAM in the hardware board when using H743 series for FC’s MCU?
Are you using another design as a template?
Have you seen FRAM used on other H743 flight controllers?
I couldn’t find any chips which looked like FRAM chips on the H743 flight controllers I have on hand. I assumed these flight controllers used the internal flash on the H743. Mateksys appears to use the H743 chips with 200MB of internal flash. If I were making my own flight controller, I’d probably use the same chip as the one used by Mateksys. I’d try to copy as much as possible from a known working design.
If FRAM is used, do you know why it is used?
Hi,
It is not necessary to have an external FRAM; you can use the internal flash, and that should work fine.
For a custom flight controller, you can control the behavior using hwdef files while building the firmware for your FC. This allows proper configuration of hardware and features at build time.
