It looks a bit homemade but at that price I bought one anyone to play with. I also have an old kit from 14point7.com (not 17point7!), I forget which version.

I see under the "technical specs" it notes 0-5V analog output, NB simulation and 96008N1 serial. This seems to be a very close match to the SLC Free from 14point7, found below.

I suspect this will end up being a PSoC chip, and basically the same as the SLC Free. I wonder if they switched to the PSoC3 series of chips, as those can be automotive grade.

I expect that its simply a CJ125 with a small microcontroller as the interface, there is no need for a PSoC.

The module arrived this afternoon, it doesn't use a CJ125, I must have misread that somewhere. The main micro is a PIC16F1716 and it also has a PIC12F1840 and a 78L05 regulator. It came with some nice paperwork and a shiny sticker but without any ESD packaging which is a big concern.

Can you take a good picture of it?

Looks interesting. Those 3 pin packages are likely mosfets of some sorts. Lots of 220 ohm resistors. It comes with some papers and a magnet for programming that initial clean air point.

a magnet???

Posted: **Sat Feb 13, 2016 10:43 am**

yep! the left-most three-pin device on the picture is a magnet sensor, which is designed for calibration. probably, that technique is used to allow users calibrate the sensor without the risk of shortening anything on the board..

I suspect the intent is that this be continuously powered, that primary PIC is ultra low operation power. The second PIC might be turned on by this larger PIC. I think the intent of the magnetic sensor is that you can POT this and not worry about mechanical switches. All in all it looks interesting.

I guess a next question is how to communicate with it. should it be analog, or digital? I haven't found a communications spec as of yet.

I found the software for this WO2. It should be easy enough to get the data over 232 stream. Getting it digitally would help avoid potential issues with analog calibration, or analog noise. It also appears they only offer the AFR, I have not found anything implying you can get additional data. I found the software at this link

It's a simple executable which is apparently using WxWidget for the gui. It should be easy enough to sniff the traffic and see what's there. The traffic is one directional, so it's probably just repeatably sending the AFR. The white wire is connected via 220 resistor to PIC12F1840 pin 6, LED and PIC16F1716 pin 11. It appears that this data stream is also how the LED is made bright, and if you connect a scope to the top side of the LED you'll see the LED is really blinking at 9600 8N1. Most of the IO on the STM are 5V tolerant, so we should be able to simply connect the 5V stream to an IO on the STM and get this data digital.

does it use ascii code, sends binary data or uses its own protocol?

Posted: **Sun Feb 14, 2016 6:59 pm**

I inquired about a spec of some sorts. I'm sure the PC program and stream is easy enough to decode, but I wonder if other things might be accessible. We'll see what comes from my inquiry.

I have got recently one such device and has produced some test. ASPX original software are not working and i use com-port terminal software for read data stream from this controller. I make small video about it, but my english is very, very bad. I am sorry.
