hi,
I have CC2540 keyfob and USB dongle, and I need to add some sensors into the keyfob, where can I connect them? Can I connect sensor pins to DEBUG pins or TEST pins?
Thanks,
Eye
TEST pins.
P0_6 and P0_7 are easily accessible.
The other pins of the keyfob are already occupied with accelerometer, buzzer, UART... and so on.

Are these pins for the I2C bus?
Why do not you get a cc2541? They have I2C :)
We are trying to create a prototype with the CC2540 Key Fob for a demo --> need to have a cool look for the wow factor.
I couldn't find CC2541 Key Fob. Not sure when the CC2541DK-SENSOR development kit will be available & if it would have a cool looking Key Fob.
So what kind of sensors can be attached to the CC2540 Key Fob? Which bus I should look for?
I'd like to know the same thing. Did you get an answer yet? Could you post it please? Could someone point me to a step-by-step example for beginners of how to connect an external sensor to the CC2540DK?
Is it not possible to interface a sensor/ADC using port 0/1 pins (2,3,4,5). I have been able to get the SCK/MOSI/MISO signals on these pins as required. But, my device disconnects immediately after initialization. Is it that the ports are hardwired and hence cannot be used externally?
