Cannot upload the code to Hercules Dual 15A 6-20V Motor Controller

Hi, everyone! I bought a Hercules Dual 15A 6-20V Motor Controller a few days ago. When I try to upload the code to the board via Arduino, it always shows the following message:

I am sure that the board type Arduino Duemilanove w/Atmega328 and the port are chosen correctly. I have tried the following different methods, but it still does not work.

  1. Try different versions of Arduino;
  2. Try different usb cables;



    Is there anyone who can help me solve this problem? Thanks!

Hi there,



Do you connect the DTR signal to your usb to ttl adapter? thanks.

Hi,



I connected all the devices as shown in your picture. It still has the same problem. Do you have other suggestions?

I have the same issue. I can’t send any code to the Hercules board.


  • In the Arduino editor, I’ve set the port to the UARTSbee, Board to Duemilanove, Processor to ATMega328P
  • I have then connected the UARTSBee to the Hercules board. The board is not powered by the battery back.
  • When I connect the UARTSBee to the computer (Mac or PC, tried both) it lights up, and the Hercules power also lights up.
  • Any time I try to update a sketch I get



    avrdude: stk500_recv(): programmer is not responding

    avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x00



    And I get exactly the same if the UARTSBee is disconnected from the Hercules.



    Q. What am I missing?

    Q. Should the UARTSBee be set to 3v or 5v?

    Q. Why can’t the UARTSBee communicate with the Hercules?



    Any help gratefully received!

I solved my version of this problem.



First, I checked that the UARTSBee was working by using a terminal emulation app, and connecting the RX/TX to check for an echo.



Second, I realised that it was possible the ATMega on the controller board didn’t have any boot loader code, or if it did, it was corrupt.

So I flashed it using another Arduino Uno (remember the capacitor across reset and ground).

Finally I made sure to the use the latest library from GitHub. I’d been using an older one which didn’t work.

Of course. all this would have been unnecessary if there had been proper documentation!

Hi there~



The bootloader on the board is quite old. You have to update the bootloader first and then you can program the arduino code from serial directly.



I use the arduino uno to burn the controller bootloader by following below instructions.

Then you can select arduino uno in board manager to burn the program to controller. Hope it helps. thanks.
