Re: Wifi rev2

Glad you got it working.

There is some information about this in the Troubleshooting Section. Under point 5.

Re: MKR Wifi 1010

Hi Tomaso,

I think trying to use any MKR board with a UNO-style shield is possible but not feasible.

Regarding I2C displays. For UNO boards you can solder the cables directly to the shield. On Arduino Mega you can use the extra I2C pins.

sorry forgfet to mention the oscilatoor is also 8Mhz ;)
Sorry, we do not support custom designs on this forum. But it seems your DSP is not initialized properly.

Hello Christian,

I'm getting very phantom readings, nothing connected to the inputs but spikes up to 100% on both channels...
What can cause this behaviour?

I just used an 8Mhz prescaler:
Hi Kevin,

The prescalar need to match the oscillator which is 6MHz.

Re: List of compatible sensors

Hello Markus, Basically no NOx sensors from cars will work as they are most certainly proprietary to avoid interchangeable spare parts. SAE J1939 is a standardized protocol for sensors and is supported by most commercial vehicles, unfortunately these sensors are 24V. We sell these on our website . T...

Re: LamdaShield2 with Mega260 and TFT Tochscreen

Very nice job, are you using it as a development tool or for calibration? - I guess it is much more convenient than using gases.

Re: CJ125 Error 0xFFFFFF

Excellent, then I can tell you that you may also have a problem with the SD-card adapter.

Have a look at this video for more information on how to use a SD-card sharing the SPI bus with the CJ125.

Thank you.

It is the lambda Shield 2
This indicates that there is a problem with SPI communication.

1. Can you please share a picture of your set up?
2. Are you using the example code without modifications?

Thank you.

Re: CJ125 Error 0xFFFFFF

Good evening, I use the lambda Shield with an official Arduino Mega. I use 12V 2A on the arduino DC input and connect lambda Shield using X7 connector. When i start the sample code I have only CJ125 Error 0xFFFFFF. Any Idea what's happening? Thanks for your help. Hi EBSolution, are you using the or...
