[参考译文] MSPM0G3507-Q1：硬件模块的应用编程接口(API)文档

您好、David

我们没有 API 用户指南、

但您可以参考 API 的源代码。

例如 I2C 的 API： DL_I2C_fillControllerTXFIFO

在 dl_i2c.h 中：

/**
 *  @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);

在 dl_i2c.c 中：

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;
}

此致、
