Pointer to latest ZMOD4410 algorithm library and sample code

Hi Fastfox,

Thanks for reaching out to the Renesas Engineering community. We are glad to assist you. 

You can download the library files from below link:

https://www.renesas.com/us/en/document/swo/zmod4410-2nd-gen-air-quality-eco2-firmware-recommended-new-designs?r=454426

Regarding interfacing to our sensor please go through the application note.in the iaq_2nd_gen.h, zmod4xxx.h, zmod4xxx_types.h and zmod4410_config_iaq2.h all the functions are defined, and they are part of the ZIP you can download form the website, you can look at the Arduino or EVK example for how it's meant to be implemented.

For I2C interface:

Library files: ARM cortex M33

If anything is not clear, please feel free to ask.

Thanks for the very quick answer. I believe the link downloads something else than ULP library however. So what I am looking for is the 2nd generation ULP library.

Also, if you could help me to find the page where that is listed instead of direct link then I would not have to ask again if I want to try some other algorithms or if I want to update the library.

Hi FastFox,

Thanks for the update. please go through the below link (for ULP library):

If anything is not clear, please feel free to ask.

Well. This part was left a bit unclear still

"Also, if you could help me to find the page where that is listed instead of direct link then I would not have to ask again if I want to try some other algorithms or if I want to update the library."

But I got stuff working now

You know what. Actually I am very confused. The link you put there in your answer downloads a zip called *1.1.0* and what I found earlier from some forum post was *1.2.0*. And even more confusing is that this is your link's release notes

1.1.0
- Damage test now after stabilization time with minimum RMOx fail limit changed to 250 Ohm
- Additional supported hardware platforms
- Example supports new EVK communication board
1.0.0
- initial version

while this is release notes from the 1.2.0 that I found earlier

1.2.0:
- Damage test now after stabilization time with minimum RMOx fail limit changed to 250 Ohm
- Additional supported hardware platforms
- Example supports new EVK communication board
1.1.0:
- Improved eCO2
- Improved RH/T compensation
- Adapted cleaning procedure and used by default
- Add growing baseline decay (replacing restart after 48 hours)
- Add sensor self-check
- Add Raspberry Pi example
- Add Arduino example
- Add polling time-out
- Add interrupt usage hint in main.c file
1.0.0:
- Initial version

So 1.1.0 is 1.2.0 and other 1.1.0 has disappeared?

I suggest that if you really don't have a page that shows the downloadable FW packages and clearly states the version you really should make one.
