More FAQ >>


1. What can I do if I want to add a RS422 interface on the MYD-C437X-PRU board?

Question:
What can I do if I want to add a RS422 interface on the MYD-C437X-PRU board?

Answer:
You might need to implement it through serial port, adding external driver chip. 

2. Can the MYD-C437X-PRU support LCD and the two PRU-ICSS Ethernet ports work together?

Question:
Can the MYD-C437X-PRU support LCD and the two PRU-ICSS Ethernet ports work together?

Answer:
No, it can’t. The two PRU-ICSS Ethernet ports are multiplexed with LCD signals, so the board can’t display LCD and use PRU-ICSS Ethernet ports at the same time.

3. Does the MYD-C437X-PRU support JTAG debugging?

Question:
Does the MYD-C437X-PRU support JTAG debugging?

Answer:
Yes, there is a JTAG interface on the board. User can use XDS100V3 emulator with the Code Composer Studio 6.2.0 to debug the board.

4. Does the MYD-C437X-PRU provide EtherCAT protocol stack source codes?

Question:
Does the MYD-C437X-PRU provide EtherCAT protocol stack source codes?

Answer:
Yes, the MYD-C437X-PRU development board is provided with demo version of EtherCAT slave static library not the source codes, user can apply to ETG for getting the EtherCAT protocol stack source codes for free.

5. What industrial protocols does the MYD-C437X-PRU support?

Question:
What industrial protocols does the MYD-C437X-PRU support?

Answer:
It supports EtherCAT real-time industrial communications protocol, and we have provided an EtherCAT slave application demo.
