DynamixelShield SoftwareSerial DIRPIN #59

Closed WilliamH07 closed 3 years ago

WilliamH07 commented 3 years ago

Hello guys 👍, First of all, thanks for your amazing works it help me a lot in my progression. Actually, I use a Dynamixel Shield with a Cnc Shield on it for controlling Nema 17 stepper motor, and for controlling everything it's an Arduino Mega. But, there is a problem, some of the motor use same pin of Dynamixel Shield in the code and it create conflit. The only way to solve this problem is to change the RX TX and DIR PINof the Dynamixel Shield. In the library SoftwareSerialyou can change the RX and TX, I try but it's not working, and for the Dynamixel ShieldDIRPIN I don't know if I can change that. Can you tell me if it's possible to do ? And how I can to do it ? Thanks a lot, WilliamH07

Hello guys, Today I am trying something to fix this problem, I just solder the cables to the pins: 2; 7; 8 and I connect them to another pin of the mega Arduino. And boom it works ! Thanks, WilliamH07

Hi @WilliamH07 FYI, Pin 2(DXL_DIR) is intended to control the data flow between Arduino board and DYNAMIXEL. If DXL_DIR pin is not connected to DYNAMIXEL Shield, you may not properly read from or write to DYNAMIXEL. Pin 7(SW_RX) and 8(SW_TX) does not require DIR control as it is a software emulated serial port. Since it is an emulated serial port, higher baudrates are not supported. Thank you.
