// Wait transfer complete
    timeout = FLAG_TIMEOUT;
    while (__HAL_I2C_GET_FLAG(&I2cHandle, I2C_FLAG_TC) == RESET) {
        timeout--;
        if (timeout == 0) {
            return -1;
        }

I'm porting some code into mbed, and am having trouble in one area. The current code uses lower level I2C code, and can determine if a I2C read failure happens because of timeout or because or a nak. It behaves differently in each case. But timeout detection does not appear to be exposed at the mbed class level. When I look at the mbed source code, I see this in the i2c_api.c file i2c_byte_read() function: <<code>> // Wait transfer complete timeout = FLAG_TIMEOUT; while (__HAL_I2C_GET_FLAG(&I2cHandle, I2C_FLAG_TC) == RESET) { timeout--; if (timeout == 0) { return -1; } <</code>> link the the whole file here: http://developer.mbed.org/users/mbed_official/code/mbed-src/file/7fa56b1b9d45/targets/hal/TARGET_STM/TARGET_NUCLEO_F030R8/i2c_api.c can anyone tell me if I can get the timeout flag, and how to do it?
