[embodiment]
The data burning anchor clamps that the utility model proposed, comprise microprocessor, adapter unit, power supply unit and control button, the power output end of described power supply unit and burning power end are coupled to microprocessor unit and adapter unit respectively, described adapter unit is used for and will be coupled to microprocessor and power supply unit by the chip of burning, the signal of described microprocessor unit response control button, output control signal through adapter unit to by the chip of burning.
In another embodiment, also increase the change-over switch unit, be used to make adapter unit between the burning power end of power supply unit and earth terminal, to switch.When burning, adapter unit is switched to the burning power end, switch to earth terminal after burning finishes.Circuit block diagram as shown in Figure 1, switch element is preferably single-pole double-throw switch (SPDT), described single-pole double-throw switch (SPDT) one end connects adapter unit, the other end is used for switching between burning power end and ground.The control button comprises MTP burning operating key and contrast operating key, and the contrast operating key can be divided into contrast again and add operating key and contrast down control key.A kind of embodiment of microprocessor unit adopts Winbond series microprocessor unit W78E516, and it is connected as shown in Figure 2 with peripheral circuit.Microprocessor receives the input signal of button and the contrast that basis signal is regulated LCD, uses variable to note the contrast difference simultaneously, uses the DC-DC chip that required voltage in the MTP process is provided.
Described power supply unit comprises three end adjustable type positive voltage output voltage stabilizing circuit LM317, first resistance R 1 and second resistance R 2 of series connection, as shown in Figure 3, the other end of described first resistance R 1 is coupled to second end of three end adjustable type positive voltage output voltage stabilizing circuit LM317, the other end of described second resistance R 2 is coupled to ground, the tie point of described first resistance R 1 and second resistance R 2 is coupled to first end of three end adjustable type positive voltage output voltage stabilizing circuit LM317, the 3rd end of described three end adjustable type positive voltage output voltage stabilizing circuit LM317 is used for external direct current power supply, and second end of described three end adjustable type positive voltage output voltage stabilizing circuits is burning power end Vout.First resistance R 1 and second resistance R 2 are used for control output voltage, change the output voltage of LM317 by the resistance size that changes R1 and R2, and formula is Vout=1.25V (1+R2/R1), Vin＞Vout+2v, and the R1/R2 precision is 1%.
The utility model object is an example with the BM4152C module, and this module is 1.47 cun CSTN, and dot matrix is 128*128, and response speed is fast, and display image is clear.Carry out the transmission of data and instruction by the parallel port with microprocessor.16 position datawires of LCD meet the Port2 and the Portl of single-chip microcomputer, and 5 control lines (CS, RS, RESET, WRB, RDB) are by the Port3 control of single-chip microcomputer.The BM4152C module needs two groups of burning voltages, then need two single-pole double-throw switch (SPDT)s, the plug-in strip of switch is received the MTPD pin and the MTPG pin of burning/recording chip respectively, two switch terminal of switch are then distinguished ground connection and the needed voltage of MTP burning, thereby control the voltage of MTPG and MTPD with two single-pole double-throw switch (SPDT)s.
