I want to connect fingerprint sensor (via SPI port )which will capture about 9K byte data, then transfer to phone to do remaining job, Is it possible using DA14580 to make it real?
Is there any example I can refer from beginning?

Hi zhilong yang,
You can refer to the peripheral examples project in the SDK in order to work with the SPI, from then you can build your own custom profile (there is a custom profile tutorial) to send the data or you can use the DSPS example if it suits you.
Thanks MT_dialog
I just wonder if internal memory has enough SRAM to store the data about 9K bytes?
Hi zhilong yang,
没有th SRAM是总共42 kbe retention RAMs. The retention RAM is in total 8KB, please have a look at the da14580 datasheet.
Thanks MT_dialog
