which library to use for i2c port in CC1310? #2597

Open Lavr18 opened 5 years ago

Lavr18 commented 5 years ago

Hi,

I am planning to connect a sensor to my CC1310 via i2c port. Which library should I use? I didn't find any that is specific to CC13xx. The only one I found is board-i2c.h for sensortag. Can I use it for CC13xx?

Best, Aliaksei

Hi @Lavr18 . Yes, that works for CC1310 as long as you configure the ports correctly. I am using it with my custom design CC1310 based platform and it works great.

Hello, I just want read the data with the i2c protocol sensor. I am trying to figure out from where the pin numbers in this code to be used for scl and sda. to read the sensor data. Can you help @rajeev1986 , @Lavr18 . I am using a launchpadxl cc1310

@Sachingit1389 The I2C pin configs CC1310 LaumchPad are defined in platform/srf06-cc26xx/launchpad/cc1310/board.h #define BOARD_IOID_SCL IOID_4 #define BOARD_IOID_SDA IOID_5

Change the above pins 4 and 5 to the I2c pins of your driver. Hopefully, this helps.

@rajeev1986 Thank you for your reply . Basically i want to read a sensor on i2c pins . Where i can find the supporting .c file for this as source code . for reading the values of the sensor

rajeev1986 commented 3 years ago

@Sachingit1389, Since launchpad does not come with onboard sensors, you will have to use the i2c sensor drivers of the sensortag located here. You will see the source files and the header files (.c & .h) of the various sensors on the sensortag in this folder. First, try to go over the drivers to see how they are structured before writing your own.

Since the contiki-os is now not being updated, any related questions should be now directed to contiki-ng repo. Hope this helps.
