Open Debugger Uart use of STC microcontroller programming interface

To illustrate, here using the model for STC 89C516RD + microcontroller

1.Uart in the Open Debugger interface and connection with the STC microcontroller as STC microcontroller requires a cold start, do not use Open Debugger VCC supply to STC, and then open the STC-ISP software, select the model and serial microcontroller, as.

2.Disconnect the power microcontroller, and then point detection MCU option, and then give the power microcontroller, the microcontroller will read out information.

3.Then point to open the program file, select STC microcontroller firmware to be programmed, then the microcontroller power, and then point to download / Programming.

4.Download/programmed, to give the power microcontroller, programmed to be completed.

5.If the power for a long time did not respond, check the cable is connected right, or attempt to re-power. Note: Open Debugger UART interface through RXD / TXD pin on the microcontroller power supply, causing power outages can not completely downloaded. TxD pins in microcontroller series with a diode (then positive), so that the microcontroller can be powered down completely cold start.
