I’m running into what looks like a compatibility issue with Arduino R4 Minima.
WPSE342 works just fine with other boards, such as Arduino Nano and Uno R3.
Issue with Uno R4 is that Sparkfun CCS811 example sketches do not output anything to serial monitor. BME280 part works OK, which in my mind excludes ‘wiring’ issue.
Reconnect the same WPSE342 another Arduino, upload the same sketch, and CCS811 works. By exaling onto the sensor I see the CO2 and TVO measurements increasing and then going back to ‘average/normal’.
Is there any ‘manual’ fix needed in CCS811 library files to make them compatible with Arduino Uno R4?
Possible solution is to modify the labrary of CCS811 via the assistance Chat GPT or Microsoft Copilot.
Or post your issue on forums like the Arduino Forum or GitHub issues page for the library. [Other users or the library maintainers might have already encountered and solved this problem].
Thank you for your response and confirmation of the compatibility status.
As the mentioned Github “Uno R4 Libraries Compatibility” project does not list currently any CCS811 library, I submitted the finding to them.
Will try all other existing CCS811 libs, however at this point chance of success appears slim.
Sad however that a maker like Whadda does not list known compatibility issues for their product. Not sure I’ll order anything in future as the premium segment pricing does not seem to give much in return.
We appreciate your feedback and understand your concerns.
The WPSE342 was designed and went into production before the Arduino R4 Minima existed. The board is based on the CCS811 SparkFun sensor, which is no longer supported. We do not manage the library; it is maintained by SparkFun. An alternative would be to use a compatible Arduino board or seek assistance from SparkFun, the original developer of the library. Additionally, you might consider using an alternative sensor to the CCS811 that works with the Arduino R4.
We regret any inconvenience this may have caused and are committed to improving our product information and support. Thank you for bringing this to our attention.
