Aduc834, I have succeed in connection by WSD，but i can't debug by UART in Keil uvision3,
Isn't Aduc834 supported by UART Debug for Keil? or only debug for simulation?
This product has been released way back and since then, it was not supported by Keil or IAR ide. However, there is an available example programs as you may have downloaded it already which written in C language that you can use on Keil. You can generate a hex file with Keil IDE once you have successfully compiled your program. After which, you can use the WSD tool to load the hex program directly to ADuC834.
I hope this helps. Thanks!
