Clarification needed

Closed this issue 3 years ago · 6 comments

Hi,

Thank you for creating such useful boards and firmware. I wanted to clarify if you are using the MX25L12835F memory chip for the IIS3dwb FFT example code ? Is the extra flash memory really useful elsewhere other than data logging ?

The flash memory is not required to make use of the IIS3DWB or these particular sketches if that is what you are asking.

Yes, Thank you.
For programming the board also it's not required right ? I am planning to make a board without it and add a iis3dwb in place of that.

Which board? Or rather which MCU. In general an spi flash is not required but I would advise you keep it on the board since it is useful.

Okay I will keep the flash, its very cheap anyways. I was talking about the Dragonfly board in which you have implemented the iis3dwbFFT code.
Also dragonfly has 2 versions with different RAM and flash size. Is the lower version with 512 kb flash and 128 kb RAM enough for the iis3dwb FFT code ?
Is the opensource board file works for both stm32l496rg and stm32l476 ?

I would use the L496, it has more SRAM for larger FFT. Both variants are supported.
