Status Return Error

I am using Arduino ATMEGA 1280 (microcontroller AVR ATMEGA1280) to control the AX12.  I have a problem since the status return (receive) packet is the same as instruction (transmit) packet. (ie, I am sending command to read the position, and expecting the status packet with no error and receive the position of the AX12, but I am getting status packet is the same as the transmit command which is read the position)

You most likely have a logic error and need to debug your code.  If you post your code someone might be able to help.

Thanks again, Mike!

Hi Taufik,

 

It seems that the direction control has not been properly done in the TTL bus circuit.

If you set both the TX_ENABLE signal and RX_ENABLE signal high, the packets sent out through the TTL BUS can be input.

When the TX_ENABLE is high, you must set the RX_ENABLE to low to block the input signal.
