pin out for UART 1 (Tx & Rx ) in CC2530 EM board

Hi,

For the pinout refer to cc2530 user's guide, section 7.1 (table 7-1) on page 79.

As for the logic, refer to cc2530 datasheet - DC characteristics (actually it's

~0v - 3.6v), so it's not a good idea to connect it directly to the RS232 on PC

(where the voltage levels are +-12v). The best way to connect it is to use

USB<->RS232, where the output of RS232 is limited between 0v and 3.3v.

Hi

For the CC2530EM pin out ref CC2530 Development kit user guide p34 for schematic.

On the remaining questions I back the answers from Igor.

hi 

thanks for ur reply.........

I already studied all thease data sheet...

but did not get PIN on board for UART1 I

got that P0.4 & P0.5 on CC2530 are used for UART but for RF05 EM board where these pins are headed?

Hi Ag,

As Tor-inge mentioned in his post, you should refer to

"CC2530 Development kit user guide", open appendix C - Schematics, go to the first

schematic sheet, this is the schematic of the Evaluation Module. Pay attention to the

P1 and P2 connectors, most of the SoC GPIO pins connected to these SMD sockets.

From here it is clearly can bee seen, for example, that P0.4 (SoC) and P0.5 (SoC)

connected to Pin #18 on P2 (socket) and Pin #3 on P1 (socket) respectively.

May be I don't understand your question in the right way, and you are referring to EM

(Evaluation Module) as smartRf05EB (Evaluation Board)?

hello Igor

I am using smart RF05 Evaluation board and  it has P1 with 36 pins and in data sheet it is P1 and P2 both of 20 pins...

this is confusing me...

I found that pin 5 and 7 are used for this but is it for UART1 or 0?

thanks.....

Hi Ag,

Let's do some clarifications. :)

Open the "CC2530 Development kit user guide" on page 6,

there you can see the "SmartRF05EB (Evaluation Board)"  and

"CC2350EM (Evaluation Module)". Now that we are speaking the

same language, let's try to understand what is connected to where.

Go to the Appendix C - Schematics. The first sheet is the schematic

of CC2530EM, there you can see P1 and P2 SMD SCOKETS 2x10.

These sockets connects to SMD HEADERS P5 and P6 on SmartRF05EB.

Now you know what are connections of SoC GPIO pins to SmartRF05EB.

Here is an example on how to follow the signals from CC2530EM all the

way to Headers on SmartRF050EB:

1. Lets say that UART1 uses alternative 1, this the UART1 mapped to 
   P0.2, P0.3, P0.4 and P0.5 of the cc2530 SoC.
2. Now, referring to page 34 (pdf page, not the document page), we can
   say that all the above mentioned pins connected to P1 and P2 SMD 
   Sockets.
3. From here we will jump to page 41 (sheet 3). Look at the P5 and P6
   headers, use the pin numbers from P1 and P2 SMD Sockets in
   order to translate the according SoC pin number to the name used
   in SmartRF05EB.
4. P0.2 goes from the SoC to pin #7 in P1 SMD Socket. Pin #7 in P1 Socket
   is the same Pin as in P5 SMD header, and its name now is "EM_UART_RX".

Hope this helps you.

Igor

thanks  for answer.....

I got it now..
