DoWatch DEV D2

Connect DoWatch to USB-USART module, see Firmware Update Extract and run STC-ISP

1. Choose MCU Type: STC12LE5A60S2
   
2. Click Open-Code-File and open a .hex file
   
3. MCU Clock: On-Chip R/C(NOT External Crystal/Clock)
   
4. RESET/P4.7 is used as: RESET
   
5. After Power-Up Reset, add extra Reset-Delay-Time: YES
   
6. Oscillator Gain(<12MHz can select Low): Low
   
7. Next Program Code,P1.0/P1.1: Not Related
   
8. Next Program Code, erase EEPROM data to FF: NO
   

As shown in the figure below:

Click ISP Programming when press the Down button of DoWatch. Start programming.

Note: Before each ISP Programming, you should make sure MCU Clock: On-Chip R/C(NOT External Crystal/Clock)!
If MCU Clock is chosen to "External Crystal/Clock", you can weld 12MHz crystal between two pads of XTAL, then set MCU Clock to "On-Chip R/C", and remove the crystal. See: DoWatch Making Guide
