USB to RS232

s1buell

Does anyone here have any experience with this topic?

 

I`m going from a TUSB2077APTRTUSB2077APTR controller to two FT232RL-REELFT232RL-REEL IC`s just to test this prototype idea.

    The first CPU project is just a project to test the CPU, create firmware etc. Its my first go at a cpu so I started with the basics (Just to play)

    The mian issue we are having now is the firmware. I`ve ordered a Atmel-ICE to start this part.

     

    I actually picked this processor mainly to work with circiut python and onboard memory storage. No more compiling. But the target was to make the CPU easy to program and for operations people to have access to the last code used (hence circuit python)

    And the application of this unit will be more for IIOT sensor reading with long range data transmission.

    The STM32F407/417 looks is really nice! The price is also good $11.06000 Digikey. I will put this on my radar.

    • I have a ton of questions but need to do some reading on the cpu first.

     

    In the end it will be for production (If no one cancels the project.....again lol)

     

    Size is important but not a constraint for us (smaller the better). Im going to use 20pin connectors to allow for any type of expantion board to be added

     

    Here a picture of the concept:

    These have a two channel DAC to allow for 4-20ma boards to be added (concept picture only). Well its an actual PCB but untested.

    BTW love the project!!!!!   (https://www.element14.com/community/external-link.jspa?url=https%3A%2F%2Fmedium.com%2F%40shabaz_yousaf%2Fviki-an-open-so… )

     

    I would be interested in producing and playing with this project....

     

    We use a PI addon boad to connect to the PI`s only for reading sensors and a little control if needed (basic stuff)

    Hi Tom,

     

    That makes sense, the dual-module approach looks neat.

    Also, it's great to hear you find the VIKI project interesting. it should just be a matter of weeks and then we'll hopefully have the documentation, BoM, etc published.
