I've have been asked this question in the past so maybe there is either some misinformation or a there is a variant/older version of this product that doesn't store settings. Obviously I cant comment on versions sold elsewhere but the ones we sell do keep their settings when power is removed.

Yes settings are saved in EEPROM and so will be retained if power is removed from the module

I've just checked but I'm not able to replicate the error. Can you provide me the following information: What operating system are you using ? What version of Arduino IDE ? What Arduino board are you compiling the sketch for ? Can you also cut and paste the full output from the bottom of the Arduino...

These steps assume you are using a USB blaster programmer snd it is connected to your CPLD/FPGA development board: 1) In the Quartus main screen open up the programmer window by clicking on the 'Tools' menu and selecting 'programmer'. 2) In the programmer window that just opened up select your progr...

I'm afraid we are unable to redistribute the software but I've just given it a quick check myself and it seems to work ok for me.

What's the error you're seeing?

Is it possible to communicate with an IP address with this combo? I'd like to send sensor data from outside (Arduino nano) via WLAN to a RasPi or PC to log that data. These modules are not compatible with wifi so you can't use one to directly connect to a Wifi router. Until now I only found Arduino...

You can do something similar with the HCPCA9685. What you're actually doing is making two copies (instances) of the library, giving each instance a different name, and then assigning one to the I2C address of the first module and the other to the I2C address of the second module. Here is an example ...

Yeah that looks like a mistake. I'll get that corrected - thanks.

It's good that you are taking a look at the datasheet but for a beginner hardware timers are a relatively advanced feature and so can seem very daunting. Understanding how they work involves understanding several advance concepts that are normally hidden away from you when writing normal Arduino ske...

The 32U4 does have hardware timers but the code to set them up and use them is different to the timers in the ATMega328 which is why the library doesn't work when you try to compile it for the 32U4.
