Utility model content
The utility model embodiment technical matters to be solved is, provide a kind of without the need to frequently plugging operation, mode of operation switches easy, the Single Chip Microcomputer (SCM) program cd-rom recorder avoiding occurring that connector damages and system.
In order to solve the problems of the technologies described above, the utility model embodiment proposes a kind of Single Chip Microcomputer (SCM) program cd-rom recorder, comprise the first connector for connecting computing machine, input end is connected to the level translator of the first connector, and be connected to second connector of output terminal of level translator and Duo Gen for short circuit normal startup mode to be switched to the lead-in wire of burning pattern, described second connector on the burning interface being plugged to single-chip microcomputer place circuit board to carry out the burning of data.
Further, described lead-in wire is three, and wherein two ends are provided with terminal, and another root end is provided with the electrical terminal for clamping described terminal.
Further, described first connector is 9 needle serial ports mated with computing machine com port.
Further, the level translator of described level translator to be RS232 level conversion be Transistor-Transistor Logic level.
Further, described single-chip microcomputer is ST chip.
Correspondingly, the utility model embodiment still provides a kind of Single Chip Microcomputer (SCM) program programming system and comprises computing machine with burn recording software and burning program, and be provided with the circuit board of single-chip microcomputer and burning interface, also comprise the Single Chip Microcomputer (SCM) program cd-rom recorder according to any one of claim 1 to 5 be connected between described computing machine and circuit board.
The beneficial effect of the Single Chip Microcomputer (SCM) program cd-rom recorder of the utility model embodiment is: by arranging the second connector and Duo Gen at the output terminal of level translator for short circuit normal startup mode to be switched to the lead-in wire of burning pattern, thus the short circuit state that only need control to go between just can carry out the switching of mode of operation, without the need to frequently plugging operation, mode of operation switches easy, avoids the situation occurring that connector damages.
