Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2640,

Hi,

I am looking for a thermometer example based CC2640R2.

And are there any recommended temperature sensors that can be easily developed with the CC2640R2?

Hi,

I would recommend to leverage the example we have for CC2640 in the BLE stack (https://www.ti.com/tool/BLE-STACK). There you will find a "thermometer" example that can be ported to CC2640R2F.

If you are interested, the following example shows how to interface CC2640R2F with a temperature sensor: https://dev.ti.com/tirex/explore/node?node=ANjJ6BsVt-mlt19gcdZFSw__swcUKHN__LATEST

I hope this will help,

Regards,

Hi,

Can PCT2202(NXP) be connect with CC2640?
This is 1.8V temperature sensor with I2C interface.

Hi,

I cannot comment on non-TI devices.

If it helps, here is the thermometer used in one of the examples I have pointed you to: TMP116. You can also review the CC2640 and CC2640R2F datasheets.

Best regards,

Hi,

Can 1.8V IO devices be connected to the CC2640?

I'm confusing about the IO level of the CC2640.

What voltage is output of internal DCDC and GLDO?

Operating supply voltages VDDS2 and VDDS3 is from 1.8V to 3.3V.

If VDDS2 and VDDS3 are supplied 1.8V, is there any problem with the system?

Please refer to the datasheet of the device: https://www.ti.com/lit/gpn/cc2640r2f

If the data-sheet does not answer your question, please open a new thread. That way hardware experts will be able to answer.

In the meantime, please remember to close this thread by marking it as resolved.
