Re: Changing the Baud rate on Hello World tutorial

Cerkit, Keep in mind the baud you are actually selecting is between the AVR microcontroller onboard the Mojo board and the FPGA. Changing the FPGA baud necessitates changing the AVR baud as well. This is very likely why you haven't been able to get it working. Actually 50,000,000 cycles per bit is p...

Re: Function Generator

GUI Works perfectly.
Rotary encoder is a bit dodgy, but functions.

Now to boost the maximum frequency and optimize the V-code.

Re: GUI Interface

Of course I would solve my own problem right after I put up the code.
Spoiler Alert






.DtrEnable = True

That has to be on.

Re: GUI Interface

Ok, so this is what I have so far. I used VisualBasic to make a form that is supposed to send a single character to the mojo. The problem is it times out. I know I could get rid of the time out, but then it hangs. It's like the app is looking for some sort of acknowledgement from the Mojo, but doesn...

GUI Interface

Help! I was trying to make a simple GUI interface for my project, but it has turned out not so simple. I have really no idea how to do this. I'm basically learning C++ for the sole purpose of making a four button application that sends a single character over USB. Does any body have some suggestions...

Re: Function Generator

Thanks. I am continuing to make modification (and learn a ton). -I just finished adding a rotary encoder to my project to adjust the frequency. -I scrapped the ridiculous amount of resistors and channels in favor of a R-2R divider that weights the bits and gives the same precision with six channels....

Re: Clock divider

So, I believe you can generate a 10MHz clock, or near enough. I'm going to give you a few ways I could see doing this and then explain why you are definitely going to want to use the first way. 1. From inside the Mojo IDE, click project>launch coregen. Use this to create a clock wizard. You can set ...

Arduino-Type Libraries

So one of the things that makes Arduino so great, way ahead of the competitors, is the IDE. Specifically, I can use Arduino with a thousand boards and a million libraries. Obviously, I'm not saying you should make more boards. However, if FPGAs are ever going to take off as a hobbyist tool, we need ...

Re: The UART tutorial in Components page does not work

So you are saying that you can echo a character on the LEDs, but not the screen? I use this code in my project and I have no issues at all. Some quick troubleshooting steps, if you haven't already tried: 1-Try using a different terminal program. I have been using RealTerm and it works really well. 2...
