Other Parts Discussed in Thread: CC2630

Hi All,

I'm trying to connect a sensor which have 1-wire connection to CC2630 using Zstack HA 1,2,

what is the API in Zstack for 1-Wire connection ?

for development I'm using SmartRF06, is it correct to connect the sensor to one of the pin in P406 ?

thx for the help,

Can you specify which kind of 1-wire Protocol you use?

Hi YK,

I'm going to use DHT22 (temperature and humidity Sensor), in the spec the output is signal digital signal via single-bus
I'm not sure about the protocol that being used, is the info enough ?

thx for the help

I think you can use GPIO driver to do it but there is no example to show how you do it. You can only do it by yourself.

Hi YK,

so i can use Standard GPIO driver ?
Ok' I'll try to look then, thx for the help

Yes, I thin it should be no problem to use Standard GPIO driver.

Hi Tonny,

You will have to bit-bang a GPIO pin as there is no default HDQ/1-wire interface available on this device. You will need to use a timer in order to get the communication sequence within the slave device's specifications.

Hi Ryan,

thx, Noted.

Hi YK, Ryan,

is this the API for std GPIO ?
IOCPinTypeGpioInput

thx for the help

Hey Tonny,

Yes for the CC26xx Driver Library (paired with GPIO peripheral): dev.ti.com/.../group__ioc__api.html
But there is also the SimpleLink MCU SDK Driver Library (GPIO/pin): dev.ti.com/.../index.html

Ryan
