[参考译文] TIDA-01012：关于 BQ27426读取和写入

尊敬的 TI 专家：

我正在研究这个项目、BQ27426_Read 和 BQ27426_write、 i2cTransaction。slaveAddress = BQ27426_DEVICE_ADDRESS、我认为这是不对的、 它应该是 i2cTransaction.slaveAddress = BQ27426_DEVICE_ADDRESS<<1；对吗？

静态 BQ27426_read (uint8_t nRegister、uint8_t *数据、uint8_t nLength)
｛
I2C_Transaction i2cTransaction；
uint8_t writeBuffer[1]；
volatile bool i=1；
易失性 bool transferOK；

i2cTransaction。slaveAddress = BQ27426_DEVICE_ADDRESS；// 7位外设从地址*
i2cTransaction.writeBuf = writeBuffer；//要写入的缓冲区
i2cTransaction.writeCount = 1；/*要写入的字节数*/
i2cTransaction.readBuf = NULL；/*要读取的缓冲器*/
i2cTransaction.ReadCount = 0；/*要读取的字节数*/
writeBuffer[0]= nRegister；

transferOK = I2C_transfer (i2c、&i2cTransaction)；//执行 I2C 传输
如果(！transferOK)｛
I = 0；
/* I2C 总线故障*/
｝

i2cTransaction.writeBuf =空；//要写入的缓冲区
i2cTransaction.writeCount = 0；/*要写入的字节数*/
i2cTransaction.readBuf = pData；/*要写入的缓冲器*/
i2cTransaction.ReadCount = nLength；/*要读取的字节数*/
transferOK = I2C_transfer (i2c、&i2cTransaction)；//执行 I2C 传输
如果(！transferOK)｛
I = 0；
/* I2C 总线故障*/
｝
｝
