MSPM0G3507-Q1: Application Programming Interface (API) documentation for hardware blocks

Part Number: MSPM0G3507-Q1

Tool/software:

Hi,

Although I'm using code taken from project examples, I'm stuggling with programing the I2C interface to the LTC2495 ADC.

Is there a programming technical reference document? The Technical Reference Manual for the MSPM0 G-Series parts is very nice for the hardware understanding, but it does not include a API.

I hope you can point me in a good direction.

Thanks,

Dave

p.s. Please note the Infineon I2C datasheet I'm attaching. I've used the PSOC for about 10 years and I'm spoiled :-).

    Hi, David

    We don't have a API user's guide.

    But you can refer to API's source code.

    Such as I2C's API: DL_I2C_fillControllerTXFIFO

    In dl_i2c.h:

    /**
 *  @brief      Fills the controller TX FIFO with data
 *
 *  @param[in]  i2c     Pointer to the register overlay for the peripheral
 *  @param[in]  buffer  Pointer to buffer of bytes
 *  @param[in]  count   Number of bytes to fill controller TX FIFO from buffer
 *
 *  @return     Number of bytes that were successfully written
 */
uint16_t DL_I2C_fillControllerTXFIFO(
    I2C_Regs *i2c, uint8_t *buffer, uint16_t count);

    In dl_i2c.c:

    uint16_t DL_I2C_fillControllerTXFIFO(
    I2C_Regs *i2c, uint8_t *buffer, uint16_t count)
{
    uint16_t i;
    for (i = (uint16_t) 0; i < count; i++) {
        if (DL_I2C_isControllerTXFIFOFull(i2c) == false) {
            DL_I2C_transmitControllerData(i2c, buffer[i]);
        } else {  // Controller TX FIFO is full
            break;
        }
    }
    return i;
}

    Regards,

    Lucy
