LP-MSPM0G3507: 3507

Part Number: LP-MSPM0G3507
Other Parts Discussed in Thread: SYSCONFIG, TMP75, TMP117

Tool/software:

I am trying to get temperature using TMP75 with I2C pin set as PB3 and PB2 but it isn't printing anything. Is it like I can't use driverlibrary API's for this purpose or should I use only API's from drivers? Please provide me with a sample running code for the same as the sysconfig file of i2ctmp in resource explorer window shows error

Have you pull up the I2C two lines external?

You can try the demo i2c_controller_rw_multibyte_fifo_interrupts

You need to add pull up external, the internal resistor in mspm0 is too large.

For mspm0 should be act as controller.

I prolly didn't get you since am not from this background. I am just learning new things. Can you elaborate?

I have configured PB3 and PB2 has SCL-SDA pins which is connected to TMP75's SDA and SCL and PB0 and PB1 has UART pins which is connected to USB to TTL. these are the details I can provide.

You can refer to this demo code

https://dev.ti.com/tirex/explore/node?node=A__AB.0jCUB3vTkGXeSK72L9A__msp430ware__IOGqZri__LATEST

as you can see it include how to read data from TMP117 that is similar with TMP75.
