| void i2c_abort_async | ( | i2c_t * | obj | ) |
Abort asynchronous transfer.
This function does not perform any check - that should happen in upper layers.

Start I2C asynchronous transfer.
| obj | The I2C object |
| tx | The transmit buffer |
| tx_length | The number of bytes to transmit |
| rx | The receive buffer |
| rx_length | The number of bytes to receive |
| address | The address to be set - 7 bit or 10 bit |
| stop | If true, stop is generated after the transfer is done |
| handler | The I2C IRQ handler to be set |
| ctx | The context pointer |
