Hello Simon,

Could you please review the latest post under this private ticket (Missing Ticket)

359159

In particular, the question about your recommended SPIM21 configuration NOT working in BLE companion configuration

SPIM21:

CS - P2.10
CLK - P2.06
SDO - P2.08
SDI - P2.09

which exact section would explain why the above recommendation would NOT work?

Thank you and kind regards,

Jamal

Hi Peter

You can follow the pin assignments "dedicated function" tab in p.841-843.

For reference, you can use the following config with for example SPIM20 and SPIM21:

SPIM20:

CS - P2.00
CLK - P2.01
SDO - P2.02
SDI - P2.04

SPIM21:

CS - P2.10
CLK - P2.06
SDO - P2.08
SDI - P2.09

Best regards,

Simon
