Below is the pin number connections. On the left is RJ1202 and on the right is EM1000. I have also attached a link to an image on the Tibbo site that explains how you should wire up the center taps of the transformer. Pin 5 and pin 8 of the RJ1202 wires to AVCC (pin 62) on EM1000. At the same time pin 5 and pin 8 of RJ1202 is wired to AGND via 220uF electrolytic capacitor and 0.1 uF non-polarized capacitor in parallel. (look at the picture - link at bottom of this post)

RJ1202 -> EM1000
1 -> 52 (optional)
2 -> 51 (optional)
3 -> VCC
4 -> 67
5 -> pin 4 on image
6 -> 69
7 -> 61
8 -> pin 7 on image
9 -> 63
10 -> VCC
11 -> 66
12 -> 64

If you still have difficulty let me know and I will try and draw a picture of the connection that I made.

settxpower() on WA1000 fails. Why?

Hi there,

My code is :

'enable power to the Wi-Fi module
io.num=PL_IO_NUM_51
io.state=LOW
io.enabled=YES

'configure the CS line
wln.csmap=PL_IO_NUM_49
io.num=PL_IO_NUM_49
io.state=HIGH 'VERY IMPORTANT! -- you must have this line, and it must be placed before...
io.enabled=YES '...this line!

'set the mac address
wln.mac="2.131.206.31.44.5" 'set correct MAC here

'set the domain
wln.domain=PL_WLN_DOMAIN_OTHER

'boot it up
romfile.open("wln_fwar.bin")
If wln.boot(romfile.offset)=NG Then
'something is wrong, react to this
End If

wln.ip="192.168.1.39" 'And don't forget to set a correct IP-address
wln.netmask="255.255.255.0"

'set output power to maximum
If wln.settxpower(255)<>0 Then
'the task was rejected for some reason
pat.play("RRRRR-",PL_PAT_CANINT)
End If

The settxpower routine fails everytime. Any ideas? Please help! Is my WA1000 broken?

Thank you Mauro

I am interested in this optoinsulator you are talking about. I am currently using a flyback diode for protection against spikes from the relay coil. Are you putting an LED in series between the relay coil and the 2n2222's collector?

Happy Christmas to you too!!

It could definitely have been the varnish.

I am building a relay controller for activating water pumps for irrigation. The pumps can be manually started and stopped via the web interface or the process could be automated to start the pumps based on certain events.

I am finding these Tibbo devices very cool so far! Thanks Tibbo!

Thanks for the reply Mauro! Yes, I did set the pin as output.

I cleaned the stripboard I am using and that solved the problem for me. Must have been some current leak from an adjacent strip...

Thanks again for the reply!!

Need help with driving 2N2222 transistor with EM1000

I am trying to drive a 2N2222 using an io line from the EM1000 in order to open/close a 5V relay. The 2N2222's base is connected to the io line via a 1K resistor.

The problem I have is that when I try to change the state of the io line to LOW it just stays at HIGH. I can't get it to go LOW. When I disconnect the 2N2222 from the io line and try again it finally reports the state as LOW. The weird thing is that there is always at least 1.5 V on the pin, whether it is HIGH or LOW.

What is going on here? And why won't it go LOW when the 2N2222 is connected?

My EM1000 won't start up. Please help!

I am using an EM1000 with an RJ1202. Everything was working fine. I started uploading a new application onto the EM1000 when it just stopped responding and the SRED LED came on continuously. After some searching I found a short-circuit on the SRED pin between the pin and the cathode of the LED (I think it was some flux paste or something). After I cleared the short-circuit I tried to start the EM1000 up again. This time nothing happened. No LED's are lighting up. RJ1202 seems dead as well.

Could the short have broken something on the module? Or could it be corrupt firmware or application? Voltage on VCC and AVCC is fine (3.269 V and 2.4V respectively).

How can I verify if the module is broken? Unfortunately I don't have an RS232 level converter, so I assume serial comms is not an option for me?

That was very useful.

EdreanE replied on November 21, 2008 10:38 to the question "RJ1202 dimensions and other specs?" in Tibbo:

Got the spec from them, thanks!

Now, how do I wire this up to the EM1000? Specifically, what do I do with the center taps of the 2 tranformers? Also, do I use the 2.5V AVCC of the EM1000 on the RJ1202 (I doesnt seem like it to me)?

EdreanE asked a question in Tibbo on November 07, 2008 15:02:

RJ1202 dimensions and other specs?

Where do I find the mechanical dimensions and pinout for the RJ1202? These are well documented for the RJ203, but I can't seem to find it for the RJ1202.

I also need to know how to wire up the EM1000 to the RJ1202.

If all this documentation is available I would appreciate it if you could point me to the page(s)!

Which pin on the RJ1202 is pin 1?
Is there someplace where I can find a drawing or something showing this?

Is an RS-232 driver chip necessary for serial comms to PC?

I have read on the EM1000 page that "RS232 transceivers are NOT built in".

Does this mean that one will have to use an RS232 driver chip (eg. MAX232) in order for serial comms between the EM1000 and the PC to work?

A comment on the question "How do I design EM1000W for serial programming?" in Tibbo:

Thanks ezuk. I will wire up serial port 0's lines and also the button (to the MD line). Before sending the schematic for board production I will give Tibbo Support a shout as well. – EdreanE, on October 08, 2008 09:56

EdreanE asked a question in Tibbo on October 08, 2008 06:54:

How do I design EM1000W for serial programming?

I have tried to find an answer to this, but I would like to make sure that I get this right the first time.

I am designing a piece of hardware that will incorporate the EM1000W as the central processor. I don't want to include an Ethernet port just for programming purposes. Therefore, I would like to be able to only add a serial port (DB9 connector) to the project which will be used to program the EM1000W. I want to be able to upload firmware as well as my program/application via the serial port. I also would like to be able to use debugging while developing the application.

Is all of this possible via only a serial port? Do I only need to wire up serial0 on the EM1000 to the DB9 connector for this to work? Any special wiring for debugging to work?
