#111019 - no work to do unitl bytes send Responding to: ???'s previous message |
well, the processor can wait till all bytes are send since no further work can be done unitl these data are send to the computer.
since the uC crystal to be used is 12MHz and the communication at 9600bps, a single byte tx would take about 1ms while an opcode will be executed within less than about a us. if i use interrupts, lots of opcodes will have been executed during a single byte transmission.normally, that is a good news.but anyway, there is nothing to be done until all the ten bytes are transmitted..so the send, fetch and wait is better for me,i think. Hey, and nobody has said anything about TL1 timer value to be set for serial communication.... |
