MSP432E401Y: Add DriverLib to existing project.

I have a different console output based on the method I use to merge the two projects. I just need to know how to add the DriverLib to an existing project for the MSP432E401Y. (Specifically to the "i2ctmp007_MSP_EXXP432401Y_nortos_ccs" example project so that I can set a specific I2C clock speed).

Mitch,

check this upper in blue:

Does it help?

One remark.

i2ctmp007.c has a bug.

The declaration:

   uint16_t        temperature;

and then:

            /*
             * If the MSB is set '1', then we have a 2's complement
             * negative value which needs to be sign extended
             */
            if (rxBuffer[0] & 0x80) {
                temperature |= 0xF000;
            }
           /*
            * For simplicity, divide the temperature value by 32 to get rid of
            * the decimal precision; see TI's TMP007 datasheet
            */
            temperature /= 32;

            Display_printf(display, 0, 0, "Sample %u: %d (C)\n", i, temperature);

In case of negative value the '-' sign added and then shift to right by 5 bits.

It is rubbish.

It should be signed variable and casted to (int) as an argument for Display_printf().

I have the same issue, no time to reread before the Post button hit.

Interesting, I actually do see "ti/devices/msp432e4/driverlib/lib/ccs/m4f/msp432e4_driverlib.a" in my file search path. The example code that I am trying to pull from is "i2c_mastermode_simple_transfer_MSP_EXP432E401y_nortos_ccs". I guess I thought that the DriverLib was not included because I cannot include the line "#include <ti/devices/msp432e4/driverlib/driverlib.h>" as done in the i2c example.

Could you check:

and the "Linked Resources" almost top on the left of the above screen?

The
#include <xxyz/xyz/driverlib.h> and etc.

statements need to be realigned with the paths above and the "Linked Resources".

It has ti on the list, and the driverlib is at: #include <ti/devices/msp432e4/driverlib/driverlib.h>. I see you have the same example open that I did, are you able to use "#include <ti/devices/msp432e4/driverlib/driverlib.h>" in i2ctmp007.c?

If I take the i2ctmp007 code and do nothing but add the line "#include <ti/devices/msp432e4/driverlib/driverlib.h>" to i2ctmp007.c, I get this output on the console:

If i do a clean build i get:

Yes, that fixed the problem, thank you Tomasz!
