Write SD card using bluenrg 332ac

JasonYang · ‎2024-10-14

Hi,

I am trying to write the IQ data to the SD card (i.e., write the received CTE pkt to the SD card). However, I found that Bluenrg-332ac has a cortex M0 core, which may not be able to drive an SD card. Is it possible to use this cortex M0 core for SD card writing?

Thanks,

Jason

Sure, a Cortex-M0 can access an SD-Card - even 8051s, AVRs, et al can do it!

eg,

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Thanks Andrew! I also wanna ask can I use cubeMX to build programs for the Bluenrg-332ac chip?
