NOTE:
The USB to serial port can be used STC-ISPV3.94 above download old versions STC microcontroller that STC89C (LE) and STC12C (LE) Series ( new version of the chip may not be able to download, there are users of the software on the highest and lowest Potter rate is set to the same time to download, we can not guarantee to do this at your own discretion ) (STC-ISP Download \u003c copy into your browser address bar \u003e :www.mcu-memory.com/datasheet/stc/STC-ISP-V4.83/STC-ISP-V4.83-NOT-SETUP-CHINESE.EXE, After downloading unzip ) Please see that this is not driving !
Download STC microcontroller steps:TXD connected microcontroller RXD, RXD connected MCU TXD, GND connected to GND, 5V connected to VCC, points to download the software , and then provide the above said four feet into the microcontroller .( Note: The MCU must have basic working conditions, including power, reset and clock ! While MCU TXD, RXD not followed by other peripheral devices, including the MAX232 and do not pick , otherwise it will lead to Download failed ! ! In the meantime , please do not disconnect the module from the computer ! )
