Hi, everyone,
I was asked to design a cc2530 with cc2591 front-end PA-LNA system. Meanwhile, I need to use P0.2-P0.5 as a (UART 0, alt 2) debug interface, as I need to connect P1.4-P1.7 (UART 1, alt 2) with hardware flow control to another device. However, it seems to be P1.4 is captured by the CC2591 EN pin, and I can't change the code to let it connect to any other pins. Is there any solution for the P1.4 pin conflict? I'm looking forward for your replies.
Thank you.
I am running into the same problem.
Hi LZH,
Why can't you simply move the CC2590 enable signal to another pin on CC2530?

Hi Fredrik,
Because CC2530 CC2591 reference design & the design note "Using CC2591 Front End with CC2530" suggest that :)
You are right, I plan to use another pin.
Thank you:)
Hi Derek,
You should be able to map PA_LNA I/O between P1_0 to P1_5. Take a look in macRadioTurnOnPower() function in
Zstack. If you configure for exemple:
OBSSEL4 = OBSSEL_OBS_CTRL1; as
OBSSEL3 = OBSSEL_OBS_CTRL1;
You should have the correct driving I/O on P1_3, instead of P1_4.
It looks better than driving itself an I/O. Let me know.
