  • DFRobot FTDI USB to Serial Basic Breakout Board (3.3V/5V)
    Great product
    Review by Jeremy
    This board works great! I use it to program several arduino based projects, as well as my OSD display for my multirotor FPV. The output voltage switch is great.

  • Bus Pirate
    More functionality than I expected
    Review by David
    I bought the Bus Pirate for I2C development work but found it has some other very useful functions: it works as a digital frequency generator (1 kHz-4MHz) and logic analyzer (using SUMP software).

  • MAX3232 RS232 to TTL Adapter
    Working from Raspberry Pi to serial device
    Review by Matthew
    I bought this so my Raspberry Pi can communicate with a serial device and I got it working on my first wiring attempt using tutorials on the internet.

Programming DAQs using FlowBotics Studio & FlowStone

Posted on March 14, 2014

By Carl Owen & filled under Electronics, Software and Apps.

  In this tutorial we are going to cover Data Acquisition boards (or DAQ’s as they are better known) and how to program them using FlowBotics Studio which uses the FlowStone graphical programming language inside. Data acquisition devices form the basis of most robotics systems obtaining signals in and out of a system from external [...]

Thanks a lot Casmat.
So I think that you recommend I use the TTL Camera.
I need 2 cams but I'll try with one and see. If you think it will be better and easier to use.

You may get out easy. Some 5v TTL gizmos may directly detect the 3.3v output of your 3.3v cmos (I think I've seen ~2v as the low dropout point for some 5v TTL gizmos). For your 5v gizmo to talk ...

Hi,

I have a Lantronix Xport Direct + and an SSC-32. The SSC-32 runs on TTL and the XPort on CMOS. Is this an issue or will they interface correctly as is?

Cheers,


The real question is, are they both 5vdc? If so then you are good to go. :D

Thanks for the reply Kurt, My JSTIK board likes 3.3v TTL signal levels. IT will work with 5V TTL stuff and 3V CMOS. Does not like 5V CMOS. I've configured my JSTIK software to 115.2K baud 8-N-1, and I removed ...
