Re: Lambda exhaust pressure compensation

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.

Re: Error lambda shiled

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...

Re: Error lambda shiled

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 ...

Re: CJ125 error code on homemade shield

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...

Re: Problem with ...2-Smartphone-Example

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...

Re: Problem with ...2-Smartphone-Example

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...

Re: Problem with ...2-Smartphone-Example

I have a genuine Uno wifi rev2 with a Lambda-shield-2. No problems with two of your examples ...-2-Gui-Example and ...-2-Example (with SD), they're running fine. But ...the third, ..-2-Smartphone-Example doesn't function. The heating doesn't start. What can be the problem? Hello Ries, What is the i...

Re: 10 bit ADC voltage conversion

Hello Henrich, Thank you for the positive feedback. If you need a reference design you know where to order it! Regarding the classic 1023 vs 1024 discussion. The ADC is 10 bits (1111111111) corresponding to the highest value of 1023 , it is still 1024 values counting the 0 value. But the highest val...
