Abstract:
1. An error detection method for data transmission in a transmission system with a first device, a second device and a data line, comprising: sending a clock signal to synchronize the first and second devices; sending at least one serial data from the first device to the second device in response to the clock signal, wherein the data line has a default logical value when no data is transmitted on the data line; sending an acknowledgement signal to the second device by the first device after sending the serial data; reading the data line to obtain a reading value and determining whether the serial data is correct according to the reading value and the default logical value of the data line after sending the acknowledgement signal by the first device; determining that the serial data is correct when the reading value is the same as the default logical value of the data line; and determining that the serial data is incorrect when the reading value is inversed to the default logical value of the data line.
