New Bipolar Boost TX and Front End

[Mdtoday]

What/where is the interface definition for your module? I could take a look at changing the FPGA HDL interface and the software drivers to accommodate it.

This is one module I have used with PIC32 and PIC24 http://tet.pub.ro/pages/altele/Docs/...0-CT_Rev.B.pdf

Available from AdaFruit https://www.adafruit.com/product/2770

4D Systems have similar https://4dsystems.com.au/products/featured-products more expensive but very nice IDE

Nextion https://nextion.tech/ Enhanced versions not so good IDE but still great for creating graphic interfaces and no SD card required for image storage.

Nextion is the one I landed on for a number of reasons.

JL, I have sent a PM

cheers

It appears that the 3.2" enhanced version is the smallest size available from the US supplier. I really like the possibilities!!

In fact, it is the only enhanced size offered!

Oh Ok, I order direct from Nextion /Itead. Part number NX4832K035 MPN: IM160611006

IM106530001 is the part number for the expansion board and FPC

Also for ease of development, get yourself a USB to TTL serial converter rather than using the SD card, much simpler.

PM just sent.

A great feature of the Nextion IDE software is the built in display simulator. Using a usb/ttl bridge you can hook it to your circuits serial port. Really speeds up development. Also allows you to try it without buying a display. Nextion uses a weird serial format, as I recall all data sent has to be converted to character strings. But once you get your sub routines written its really easy to use.

Hi Altra,
Yes, sure helps to have the simulator and the serial bridge makes life that much easier. The format is a bit strange but not too bad.
The thing I like about the Nextions over other similar products is that you don't require the SD card to hold your graphics pages.
Button changes can use just 2 backgrounds, all on, all off, then you can just select a portion of either page or background (such as over a button) to indicate on/off or pressed state.
The 3.5" enhanced version has 32Mb flash and 8K Ram which is plenty for most applications.

I have been using Nextion for a long time he is great can be used for multiplicity application i use it for my magnetometer it's a language pretty easy to learn.

I didn't get the enhanced version, but wish I did just not to be limited. For most applications the standard is fine. The enhanced is needed if you want to do the simulated analog gauges. These displays are great for one off projects. Another good choice https://riverdi.com/product-category/eve/


@Orbit your graphics look great. Do you have a video of the display reacting?

[Orbit]

I'm using an enhanced version NX8048K050 the first version was written in 2017 and it contains graphics in Nextion depending on the voltage sends command what color to display ,and this is the version you can watch, in the second version it works dynamically which works a lot faster it contains in the processor and sends a command which a specific number for a particular coloractivates ,in both versions it measures 17 times per second then from 17 measurements I draw a mean average and I send a command to Nextion .I will post the second version in a few days that you can see ....https://www.youtube.com/watch?v=NQahEUWLF8k

I'm personally very happy with the speed of the reaction the speed of the processor to Nextion is 57600 baudsrate

Thanks Orbit! Look forward to your next video.

BiPolar PI using Nextion for user interface

Using the Nexion Editor. I have started coding up the user interface based on the Nextion 3.5 Enhanced. With just the little I have done with three screens indicates that the Nextion interface will oflfoad considerable processing and development effort from the Cmod-A7. I can already see that I can remove the user interface, PmodOLEDrgb HDL and Flash interface modules along with 5 interrupts and 11 external ports.. The Nextion interface will occupy only 2 external ports and use the Vivado uartlite serial interface with interrupt. Also large chunks of code (both library support and application) can be discarded. I have already identified about 2800 lines of "C" code that can be omitted. Most of the user interface running in the Nextion runs without needing any communications with the Cmod-A7 embedded microprocessor (upc). Almost all of the TX-RX operational parameter initialization can be accomplished by the Nextion and sent to the TX-RX thru the embedded upc. The parameter storage for retention between startups can be handled by the Nextion. The communications load between the Nextion and Cmod-A7 is minmal 50-60 bytes from the Cmod-A7 at 5ms intervals. Communications from the Nextion back to the Cmod-A7 is only needed when there is a change to the operating environment. All of the communications can be handled with no bottlenecks with a baud rate of 115200 and the baud rate can be increased to 230400 if needed.


I am going to freeze the current project at it's current state and start a new branch using the Nextion as the user interface. I will leave the link to the current project archive active in case anyone wants to continue development using the current user interface hardware. Future project archives will include the Vivado TX-RX development archive and the Nextion user interface development archive.

This Nextion interface is amazing!

Nice work KingJL, the Nextion is a great little time saver isn’t it.
I use the expansion port with 3 or 4 buttons panel mounted just for the frequently used functions like Gb and pin point etc, saves wear on the touch panel. They run in parallel with graphics buttons. I have used them for about 18 months and so far no failures on the touchscreen or module in general.
