Hi team

I am quite impress with this touch LCD interface, just wandering how can I find out more about this? eg what is the hardware and more importantly, what software does it use to develop the GUI?

Here is the image, link, it's the interface for a Flashforge 3d printer.

Thanks team!

 

It is probably one of these...

Your device only says 3.5” color lcd. Here’s the standard 480x320 that folks use with raspberry pi. It could be run using 8 bit chips as well. I have one in my creakily that runs an atmega2560. https://learn.adafruit.com/adafruit-pitft-3-dot-5-touch-screen-for-raspberry-pi

You can get 800x480 as well but you will want a cortex M3 for one of those. They go up in price as they get denser. You can find cheaper than the Adafruit website but they have good documentation there. A friend of mine just upgraded to a 800x480 on his opensource RC transmitter.

There are number of ways of doing the images. Static screens like the ones used for menus are not very hard. Image files are usually stored on SD cards.

Are the update fast?

 

With a raspberry pi yes. It all depends on what you’re doing. Check all the examples out there. Don’t forget they have Cortex M4 32 bit running 700MHz on the newest Teensey. For menus you don’t need it.

Can you briefly explain how to implement a GUI, or point me to some links please?

 

Here are a few, just search it up in google if you need more.

You can check out STM32F746G-DISCO and TouchGFX.

The TouchGFX is pretty impressive, do you have first hand experience with this? Would love to hear what you think of it.

 

I have been using STM32F MCUs for quite awhile now, in particular STM32F407 and STM32F746-DISCO.
As you say TouchGFX is very impressive. STM32F as a whole is very impressive.

I had already written my own graphics package with LCD touch screen before TouchGFX came along. Hence I didn't migrate to using it.

Do you mind me asking what type of application you use STM32F4 and STM32F7 for?

 

I posted a few threads on my STM32 journey here on AAC.

I began using an STM32F407 to drive a VGA screen directly with no additional chips required. This became a gamma-ray pulse height analyzer with a 42Msps ADC.

When the STM32F746-DISCO came available, I moved over to the touch screen LCD. I have plans to create an oscilloscope eventually.

I have been using this as audio spectrum analyzer, muscial note analyzer. I have plans to use it to record bat sounds.

Sounds like some very cool projects can take advantage of this powerful MCU!

 

When I get back to my home base in mid-October I will start a blog to show how you can create a DIY 2-channel oscilloscope based on the STM32F746G-DISCO.

Does it need a lot of DSP to make a scope like this?

No. I intend to post all the code starting from square 1.

Do post something here when you start ;-)
