NRF24LE1 QFN24 SPI problem

[Andrii]

Hi!

Whether there are any special requirements for SPI chip NRF24LE1 labeled NRF B 24LE1D ?

My programmer (mPro) do not work with this chip SPI.

rergards,

Andrii.

I am not familiar with that specific programmer, but if the pins are mapped out according to the FlashSPI pin out for the 24 pin version of nRF24LE1, it should program. The FSPI interface pin out is documented in the datasheet at chapter 17.

It might be that this programmer does not supply VDD to the nRF-chip, try powering the nRF with 3.3V or verify with the programmer manufacturer if it's a requirement. From the documentation on the site that you linked to, it seems to provide a 3.3V source.

Best regards Håkon
