  1. @D@n thank you, I'm definetely going to read those links (already read the ones about begginers and I totally can see myself in it). And the reason why I'm working with a FPGA is because my instructor wants me to use one in my thesis, with a microcontroller it would be much easier and probably would be done by now. @zygot before I've made this post I used the search option, I suppose that section also shows on the search results so I haven't found any post that helped me. @jpeyron my second point was exactly that two pins, I may have not be clear enough. And I was wondering how that two pins would make a difference from other UART examples
  2. Once again I'm sorry if I'm asking what can be considered silly questions, but I'm diving into the FPGA world by myself and I'm having serious dificulties finding documentation or examples that fit my questions. I'm using a Cmod A7 and I want to develop a GUI to let the user define some parameters. Through what I've been researching I believe the way to do it is using UART with the micro usb of the board. I've seen some examples of UART implementations, some I found in responses here on the forum, but due to my lack of knowledge it seems to me they lack important things so I could understand them. So I'll ask two questions: 1 - I believe that if I want to let the user change some parameter, that parameter must be a register and I need to know its adress. But how do I define the adress of that register? I haven't been able to find any example for this. 2 - It seems that the Cmod A7 has two UART ports according to the XDC file, so exactly how am I supposed to use them? Will that make a diference from examples like this one? João
  3. First of all I want to apolagize if my questions sound a little bit dumb, I'm not familiar with FPGA's. To give a little bit of context, my project consists in generate a digital signal (a triangular signal, close to a sawtooth) through an FPGA (Cmod A7) and then convert it with a DAC. The signal won't be static, i.e. the user should be able to change its slope. So for the user to change the slope, I need an interface to control some register. My question is exactly this, is there any interfaces available to write on registers in real time? I intended to use LabView with this interface https://www.labviewmakerhub.com/doku.php?id=libraries:adept:start but unfortunately I'm not being able to connect the FPGA with this, so I'm looking for alternatives.
