摘要： In a first controller that runs a first control algorithm and a first interrupt service, wherein the first control algorithm includes a first series of commands repeatedly executed in sequence, wherein the first interrupt service performs a second series of commands when the first interrupt service is triggered, wherein the first controller includes a first free running counter with a counter timer value that repeatedly increments and resets when the counter timer overflows, a data communication method comprising the steps of: in each sequential execution of the first series of commands: reading a data signal to be transmitted; responsive to the data signal, computing an on-time; setting a first edge of a serial transmission signal; and loading a register with a value equal to a sum of the first counter value and the on time; independent of the first series of commands: comparing the first counter value to the register value; when the first counter value equals the register value, triggering the first interrupt service; and when the first interrupt service is triggered, resetting a second edge of the serial transmission signal, wherein the first edge is not set again until a new data signal to be transmitted is read.
