<div class="markdown_content"><p>Finnaly i get it working. There was a line in the file that set the ADS1015 chip in /boot/firmware/config.txt which i removed and after that the ADS1115 has a green turning circle and i got values. i created a new component so it fits our ADS1015. see screenshot. It works also with Codesys Control for Raspberry Pi 64 SL after adding the ULINT_TO_UDINT conversion in the library.<br/> i think the chip was all the time in use by the Raspberry pi itself.</p> <p>Thanks for your help!</p></div>

<div class="markdown_content"><p>I don't have a multiplexer so it very weird that it connects with that multiplexer.<br/> If i do a I2C scan on the PI terminal, i only get the device addresses 0x48 and 0x51. One for the ADC and one for RTC. <br/> I will try again with your libraries</p></div>

<div class="markdown_content"><p>Ok,<br/> here are the libraries I use.<br/> First of all, try to get the ADS1115 to run completely on its own. Without MUX or other sensors.<br/> As muxboard I use this one:<br/> <a href="https://www.digikey.de/de/products/detail/sparkfun-electronics/BOB-16784/12714950?utm_adgroup=&amp;utm_source=google&amp;utm_medium=cpc&amp;utm_campaign=PMax:%20Smart%20Shopping_Product_Zombie%20SKUs&amp;utm_term=&amp;productid=12714950&amp;utm_content=&amp;utm_id=go_cmp-18521752285_adg-_ad-__dev-c_ext-_prd-12714950_sig-Cj0KCQiA88a5BhDPARIsAFj595gkPXWPT8aa-EixL97BDWjO988WDhcx-iHOVbqb_H8CLpHBcwLuJW0aAu1JEALw_wcB&amp;gad_source=1&amp;gclid=Cj0KCQiA88a5BhDPARIsAFj595gkPXWPT8aa-EixL97BDWjO988WDhcx-iHOVbqb_H8CLpHBcwLuJW0aAu1JEALw_wcB" rel="nofollow">https://www.digikey.de/de/products/detail/sparkfun-electronics/BOB-16784/12714950?utm_adgroup=&amp;utm_source=google&amp;utm_medium=cpc&amp;utm_campaign=PMax:%20Smart%20Shopping_Product_Zombie%20SKUs&amp;utm_term=&amp;productid=12714950&amp;utm_content=&amp;utm_id=go_cmp-18521752285_adg-_ad-__dev-c_ext-_prd-12714950_sig-Cj0KCQiA88a5BhDPARIsAFj595gkPXWPT8aa-EixL97BDWjO988WDhcx-iHOVbqb_H8CLpHBcwLuJW0aAu1JEALw_wcB&amp;gad_source=1&amp;gclid=Cj0KCQiA88a5BhDPARIsAFj595gkPXWPT8aa-EixL97BDWjO988WDhcx-iHOVbqb_H8CLpHBcwLuJW0aAu1JEALw_wcB</a></p> <p>All other boards don't work for me either.<br/> The terminating resistor is missing</p></div>

<div class="markdown_content"><p>I also installed your codesys version with the codesys for raspberry pi package version 4.7.0. but with no succes, only the TCA multiplexer has a constant green turning circle, the ADS1115 still changing from running to not running.</p></div>

<div class="markdown_content"><p>I succeed to change the device to PI_SL but still the same problem of the I2C device switching between running and not running. the only difference with your project is that yo use I2C_master device version 4.7.0 and i 4.7.13, for GPIO i also use the 4.7.13 version and you the 4.7.13. Can you send me the older version of the Raspberry PI pheripals library, because i cannot choose lower version then 4.7.10 for the GPIO and I2C_master device</p></div>

<div class="markdown_content"><p>Sorry, wrong expression.<br/> You have a 64bit system, so do I.<br/> You can also use the 64bit runtime, but most bib and commands are 32bit and are not properly supported.<br/> I had read somewhere that there are problems with I2C. That's why I recommend switching to PI_SL and using the correct gpio.</p></div>

<div class="markdown_content"><p>This is the operating system and has nothing to do with the runtime. Unless you use 64bit commands. You can see for yourself that you have errors with 64bit compilers </p></div>

<div class="markdown_content"><p>We use a Compute module 4 it's 64bit based, so i cannot change it to sl.what are the possibilities to get the i2c working?</p></div>

<div class="markdown_content"><p>I took a look at your project.<br/> First of all, a Raspbery Pi4 is installed.<br/> You must use the GPIOs_A_B(GPIOs B+/Pi2).<br/> The error ULINT can't be set to IDINT.... with your project as well.<br/> If I change your project to ‘CODESYS_Control_for_Raspberry_Pi_SL’<br/> the error is gone.</p></div>
