Solution for C and R in SMD...

Nice mod wolf!

I future proofed your photo. I hope you don't mind.

Hi Christian!, Very thanks You!!

with code correct:

now I can calculate Ip with Ip = 1000 (UA-1.5) /61.9*17 where: Ua = (ADC / 1023) right?}

Regrads,

That looks about right, except you UA need to be (ADC / 1023) * 5V.

See 4.1 in the Technical Manual.

Good luck!

Hi Kevin,

SPI speed should not be an issue. Currently it is running with an SPI clock in kHz.

You actually don't need any SPI communication at all. Just set adcValue_UR_Optimal to 175 and remove everything SPI. Have a look at the Lambda Shield smartphone code.

Is it possible to use LSU4.2 wideband? Just change the resistors to the values indicated in the CJ125 manual? or do you have to change something in the code too? -R4 from 301r to 80r -R6 from 31.6k to 10k. H! To be honest I have never tested with an LSU 4.2, never seen the reason for it. But accord...

bosch 0258988001 As long as it is a genuine Bosch sensor and not an aftermarket one there should be no issue with he sensor. Well, lets start analysing your output. 1, 1 ,10495,323,859,860,12539 1 = This is actually a problem, it sounds like you are using the original Lambda Shield, but this hardwa...

but all time serial print shows heating sensor, is normal?

No that is not normal, your values indicate a cold sensor. This is typical for certain aftermarket sensors. What sensor are you using?

Could it work if I invert the input signal (digital pin 5) mcp14e9 with a transistor?

Great, problem solved! Have a look at our Lambda Shield 2 on how you can skip the driver completely.

It is rare, I checked the schema over and over again and did it the same as published, I see no difference. The published schema is correct? Hi Cristian, the schematics is the originals used for the PCB. Can you make sure when the MOSFET is off you get 0x28FF from the CJ125 with 12V supply? On the ...

Hi Cristian, I manufactured and assembled the lambda shield according to the schematic Interesting you made your own. If you don't mind me asking, how come you did not order one from our website? I have a question about gnd of MCP14E10-E/SN, This must connect to comon GND? That is correct, the GND p...
