hi 你好
請問, TM4C123 是否支援I2C , I2C_MASTER_CMD_QUICK_COMMAND 的模式,
我設定此模式, 會造成系統崩潰, 我是運行在TI-RTOS 下,
我的程式如下, 當執行到 I2CMasterControl(I2CPortBase[I2C->bus], I2C_MASTER_CMD_QUICK_COMMAND); 就會崩潰,
//Initialize Master and Slave
I2CMasterInitExpClk(I2CPortBase[I2C->bus], MAP_SysCtlClockGet(), iic_params[I2C->bus].bitRate==I2C_400kHz ? true : false);
// Specify slave address
I2CMasterSlaveAddrSet(I2CPortBase[I2C->bus], I2C->address, false);
// Initiate send of address from Master to Slave
I2CMasterControl(I2CPortBase[I2C->bus], I2C_MASTER_CMD_QUICK_COMMAND);
2. 我的環境如下
tirtos_tivac_2_14_04_31
TivaWare_C_Series-2.1.4.178
IAR 7.4
TM4C123BH6ZRB
謝謝

这个文件夹下面就有例程的
不支持I2C_MASTER_CMD_QUICK_COMMAND 的，您可以看一下 
的
12.2.1.3 ROM_I2CMasterControl
Controls the state of the I2C Master module. Prototype: void ROM_I2CMasterControl(uint32_t ui32Base, uint32_t ui32Cmd) ROM Location: ROM_APITABLE is an array of pointers located at 0x0100.0010. ROM_I2CTABLE is an array of pointers located at ROM_APITABLE[3]. ROM_I2CMasterControl is a function pointer located at ROM_I2CTABLE[18]. Parameters: ui32Base is the base address of the I2C Master module. ui32Cmd command to be issued to the I2C Master module Description: This function is used to control the state of the Master module send and receive operations. The ui8Cmd parameter can be one of the following values: I2C_MASTER_CMD_SINGLE_SEND I2C_MASTER_CMD_SINGLE_RECEIVE I2C_MASTER_CMD_BURST_SEND_START I2C_MASTER_CMD_BURST_SEND_CONT I2C_MASTER_CMD_BURST_SEND_FINISH I2C_MASTER_CMD_BURST_SEND_ERROR_STOP I2C_MASTER_CMD_BURST_RECEIVE_START I2C_MASTER_CMD_BURST_RECEIVE_CONT I2C_MASTER_CMD_BURST_RECEIVE_FINISH I2C_MASTER_CMD_BURST_RECEIVE_ERROR_STOP Returns: None.
