Other Parts Discussed in Thread: CC2540

Hi,

I'm new to the cc2540, and i was wondering how to connect a signal externally to the test pins ?

i set the AIN6 as analogue input but was also wondering where should i connect the ground pin of my signal on the keyfob ?

Thank you.

Hi Husain,

Have you reviewed the Keyfob reference schematic & layout: www.ti.com/.../cc2540keyfob-rd
You should be able to find a suitable ground connection after reviewing the design files. If not, please reply.

Best wishes

Hi JXS,
Thank you for your quick reply, would PIN1 on the debug pins act as a suitable ground for my input signal into P0_6 ?

Hi Husain,

Yes, PIN1 on the SoC Debug/Flash header is a suitable ground.

Best wishes
