Welcome to the forum Ali. I took the (//Calculate SupplyVoltage) from Code Line 472 can i do it better or different so i will not use it twice ? This line is only executed once during heating so if you want to value to update you need to perform the calculation like you are doing now for every updat...

Can be used the sensor BOSH LSN 11??
This sensor has only 4 Wired

Thanks 😆

Hello, I am not familiar with this sensor. Are you referring to this narrowband sensor?

Hi, are you sure you are reading from the right ADC-input?

It looks like you are reading from a floating analog input pin.

How is performed the Lambda exhaust pressure compensation because I know that Bosch request that to have a relevant lambda value ( to minimize error ) Hello, you would need an exhaust pressure sensor and compensate as Bosch describes in Y 258 E00 015e. I have never seen anyone actually do this eith...

I'm so confused that I'm trying everything. Thank you. It already works as it should.
I'm satisfied.

Excellent, I am glad to hear that the problem has been resolved.

Great. Thank you very much. I compared PINout and it was clear to me. I have it connected to Mega 2560 and softwear for shield 2. I'm a little confused by the warm-up time. The heating is still flashing. The probe heats up, but it never ends. You can not use the software for Lambda Shield 2 on a La...

Hello, Thank you for the diagnostic data, I can see that you are using an original Lambda Shield that you recently ordered. There seems to be an issue with the SPI communication. The other values look good. The original Lambda Shield that you have ordered is not SPI-pin compatible with Arduino Mega ...

Hi Cristian, 2,0,10495,1023,226, 1023 ,12769 Besides UA being way too high and UR being too low I see another issue and that is the UB values. This indicates that you are powering your shield which a much too high voltage as you are reaching the limit of the ADC for the voltage divider used. This is...

Your answer sent me in the right direction. It was a little more complicated than you wrote, but the Arduino page gave sufficient extra help and now everything is working properly. I think that the way you're working, building and selling boards, publishing software for it, helping people to get th...

I hope this is the way to implement a picture. If not, it only shows 'No Signal' nothing else. The lamda sonde doesn't warm up and the green leds on the shield don't light. Excellent, so it is not really a heating issue. Simply nothing seems to work. This is most likely because the firmware of your...
