This library enables the usage of RETAIN data on the Raspberry Pi platform which natively does not support this.
It is based on the mcp7941x RTC chip which also contains 64 bytes Battery Buffered SRAM.

Hello Team Codesys, Nice to meet all you on Codesys forge platform
Hello everyone ,
I am calling on you because I can no longer compile and register a driver at all, and have it available in a program
I don't remember the steps anymore ....
when you have the ".library" and "devdesc.xml" files.
as in the posts proposed by other contributors
if you could describe this to me, I would appreciate it very much.
(I spent the day doing trials)
which driver do you want to compile a new one or one of these old which are ready for dowload in this thread?
I want to compile this one :
MCP4728.devdesc.xml [2.38 KiB]
I2C_MCP4728.library [335.03 KiB]
there are some months I had been able to do for the MCP3208.
but now I am unable to repeat the procedure ....... sorry I forgot all.
I reread this post, but it didn't help me
just install the MCP4728.devdesc.xml to the device repository
and install the library to the library reporistory.
Add under I2C master the device...
I tried to make it complicated ...... by trying to change the path of the file, really sorry.
on the other hand, for the I2C network it is 502 for the type in the xml file, isn't it?
I'm sorry to notice that some of the links in the top post do not work. In Particular i'm searching for the original ArduinoIO Driver by Gerhard Schillhuber.
Can someone please fix the links.
You are right. I also already heavily searched for the correct post, but didn't find it.
The problem seems to be in the linking of the posts. Keeping links between the posts and attachments was the most tricky part, when we migrated the forum.
@eschwellinger do you have the old projects still around? Maybe you can at least upload them?
I am looking for the arduino i2c driver.
it appears in the list but the link is broken. "http://forum.codesys.com/viewtopic.php?f=23&t=5872&x=10868&p=10868&lan=en"
is there anywhere to see this i2c drive?
here they are.. hope this helps
It has helped me a lot.
Thank you so much
I will will try with your link and let you know.
thank you very much for your support. and team Codesys, Sp. Roland Wagner
I am trying to use the PCA9685 board with PWM output. I can only seem to change the voltage never full range of 0V for no PWM, and 5V for full PWM. I can only change Frequency [Hz] the higher the frequency the higher the voltage range, also other parameters do not effect it like _alrMin, _alrMax, _freq, _rPeriod
100hz Frequency = Adafruit_PWM.alrPWM :=0 is 0.468V and 1 is 0.972 output does not appear to actually PWM, higher frequency
400hz Frequency = Adafruit_PWM.alrPWM :=0 is 1.949V and 1 is 3.894 PWM does not go to zero, and closer to 100%
Hello, the link http://forum.codesys.com/viewtopic.php?f=23&t=5872&x=10868&p=11014&lan=en for the library of mcp23017 does not work (anymore). Can anyone provide me the file?
you need to select 'more posts',
As most of the posts are moved here around 2015, what would be the right version of codesys to run? Would it be better to install a older version of codesys or should i keep on downgrading libraries?
Is there any work done to update theses libraries?
It´s been a few years since the last update in this post, are there new libraries/devices for raspberry being added/posted somewhere else?
