CH340G Programmer

Development Tools IDE 1.x
1

A while ago i settet up my Arduino Pro Mini with a CP2102 Programmer. Everything worked fine for the first 10 times, then my programmer burned down (It literally smoked). So i ordered a new one. This time it was a CH340G Programmer, and it just won't work.

I checked:
Programming Port -> fine
Board -> fine (Pro Mini)
Processor -> fine (5V 16Mhz)
Connections -> fine (RX to TX and TX to RX)
Nothing attacked to RX/TX on Board -> fine (Removed Bluetooth Module)
Driver installation -> fine (Reinstalled twice)

I always get this message:
avrdude: stk500_recv(): programmer is not responding
and then 10 of these:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00

The CH340 works and works well.

Firstly check which ports are available in the IDE without the CH340 connected then which ports appear when you plug it in.

Assuming you get a new port see this here on how to connect it to a pro mini.

All the wires are connectet right. (I checked it again)

DTR -> DTR
VC (5V) -> VCC
GND -> GND
RXD -> TXO
TXD -> RXI

The COM10 Port is selected in the Software.

Thanks anyway

Post a picture of your setup.

The pinmap on the Pro Mini Board is:

GND
GND
VCC
RX
TX
DTR

Have you loaded any programs on to that board before?

You mentioned your last USB to serial converter burning out.

Was it connected to this pro mini or is this a new board not programmed before?

Thank you I fixed it!

The old programmer probably destroyed the programming unit of the Atmel microcontroller. The old programm was still running on it. Luckily i have about 10 Boards.

If the old programme excessively hogs the serial port then you may find a simple reset before upload would fix the issue.

Tried it, does not respond. I think it burned the programming unit in the chip.

The chip is programmed by serial. I would be surprised if you did part blow it. However the Pro Mini boards are cheap so scrapping one is not a big issue.
