Hi Analog Devices,
I have used the following example to configure and test UART functionality of ADSP21489 EZ Kit.
C:\Program Files\Analog Devices\VisualDSP 5.0 (2)\214xx\Examples\ADSP-21489 EZ-Board\UART echo back_C
Firstly, In the readme.txt of the example, it is mentioned to connect UART connector (P1) to any hyperternimal program on PC.
On reading the EZ KIT manual, I have found that the UART Tx/Rx signals are available at RS232 connector (J2) [see attached screenshot].
I am now confused why is it mentioned as UART connector (P1) of the EZ-KIT in the example documentation?
I can also measure signals at (2) and (3) pins of the J2 connector on running the echo back example. Please clarify?
Secondly, on the PC side, I do not have a RS232 serial port. Therefore, I am using an USB to serial converter of Prolific technologies.
I have already tested this converter on another uC with UART communication and it works perfectly!
However, when I used the same connector between the J2 of Ez-KIT and my USB of PC, I just get <FF> <FF> <FF> on the terminal software (Iam using PuTTy). I have set the UART parameters in the software exactly as mentioned in the example.
Am I missing something here?? Please help! Thanks.
