CH340G and Standalone UNO R3 Got ERROR "avrdude.exe: stk500_getsync(): not in sync: resp=0x00?" Answered
I bough the CH340G USB-TTL with 6 pin (GND, CTS, VCC, TX, RX, DTR). The CH340 driver already installed, the arduino bootloader also already burn to ATmega328P-PU. When upload the sketch using FTDI or PL2303 or ATmega16U2 is okey and no error found. But if Ia using CH340 and connecteed below pin:
Arduino VCC ==> VCC CH340
Arduino GND ==> GND CH340
Arduino RX ==> TX CH340
Arduino TX ==> RX CH340
Arduino RESET ==> DTR CH340
The error always appear as "avrdude.exe: stk500_getsync(): not in sync: resp=0x00?" event the speed on the port setting already change at 9600; 19200 or 115200. Iam also trying with IDE 1.6.0, 1.0.5 and 022 the error message are same. May be someone can help me please?
