<div class="markdown_content"><p>Hello, trying to integrate the C code in Automation Builder. The purpose of this code is to convert base64 encoded message. The C function will be called in CoDeSyS.</p> <p><img src="./attachment/base64_decode.jpg" width="50%"/></p> <p>The base64 converter code works successfully in MPLAB (running on PIC32)</p> <p><img src="./attachment/call_of_base64_decode.jpg" width="50%"/></p> <p>However when I try to integrate it, I cant do it, since in available data types I cant choose array of uint, only data types without array. The picture shows the dialogue of C code app in Automation Builder (CoDeSys data types).</p> <p><img src="./attachment/C_code_ab.jpg" width="50%"/></p> <p>I had a thought maybe I can use a STRING, as array of UINT, in CoDeSys by applying pointers, but not sure.<br/> May be some has encountered the same problem ? Or knows possible solution ?</p> <p>I apologize for offtopic, but dont know where to ask, thought CoDeSys forum best place, since Automation Builder refers to CoDeSys data types.</p></div>
