Re: SPI Pulldown Resistors Purpose

Hi, An educational query for myself, looking at the schematic, there are pulldown resistors on the SPI lines, but literature I have read insists that there is no requirement for pull-down/pull-up resistors on SPI lines. Only info I could find is regards mostly using pull-up for certain scenarios. T...

Re: Two lambda Shield 2 on Arduino mega

Hello, I'm currently using a lanmbda2 Shield on an Arduino mega to tune my bikes. The disadvantage is that I constantly have to dismantle the lambda sensor to move it from one cylinder to another. I currently only have twin-cylinders but the latest is a four-cylinder. I'd like to know if it's possi...

Re: Lambda Shield V1- Arduino Mega 2560

Hi, Does Lambda Shield version 1 work with Arduino Mega? I can run it with Arduino Uno, but when I connect it to Mega, it doesn't draw any current. I need help urgently, thank you for your help. Hi Ugur, The original Lambda Shield was only compatible with the pins of Arduino Uno, specifically the S...

Re: Using shield in car prewarming or not?

Hello CarUser,

Bosch are quite clear on this in the documentation: "Heating the sensor before the engine is started is not allowed."

Hope it helps.

Re: Uno Wifi Rev 4

It seems to have something to do with the reset pin. If I disconnect that, it works fine. Is the reset pin important on your shield? Thank you for the observation, it is only used to reset the CJ125 if the shield is reset but it should not have any importance in the function. I can see in the schem...

Re: Reading lambda values higher than 10

I have a diesel engine and would like to be able to read lambda values at idle and cruise, which are leaner than the arduino code is programmed to support in the lookup table. Is there a more detailed lookup table available or will this require the values to be calculated on the fly? I can't seem t...

Re: Uno Wifi Rev 4

Hi, I have found that the Lambda Shield 2 Example works on the new Uno Wifi Rev 4 board, returning the expected 20.95% result in free air. However, I can only do this by first uploading the example without the shield attached. If I try to upload any program with the shield attached I get a board no...
