Changing the data direction of Smart Servo Shield
Account cancelled 2016-11-18 05:32:11 1602 Views3 Replies Hello, I recently have been tweaking the Digital Smart Servo Shield of DFRobot. Looking at the datasheet I have a question. How do you change the data direction of the Smart Servo Shield? As the description says, this board is a half-duplex circuit. So according to this feature doesn't the shield should have a I/O pin for the data direction control?
I am guessing the TX is an Active Low control and the RX is Active High control. But the circuit only shows an PD_TXD, PD_RXD with a SN74HC connected to the Rob_UART.
How do you change the serial communication direction of this half-duplex circuit?

Thanks for your support to our DFRobot.
So sorry, so far, our Smart Servo Shield only support to send data, dont support to receive data from the servo. This is a weakness of our products. So I will give a feedback to our team, hope there will be an update later.
Have a good day.
