Hello there ;
I became a new member of the forum.
I new download B4R and looking documentions.
I have a project at the university and I need your experience and suggestions.

I must made app with 4 button + LCD TFT screen + toucpanel with best PRICE

my friend suggested me a wemos card & B4R IDE (first look , its easy like VB).

needs your sugges:
  • LCD TFT panel + Touchpanel
    • (Store has alot type and size and aliexpress.com/store/900905)
  • Which comminication protocotol for screen (I2C, SPI, STM32... my mixed brain)
  • Which comminication protocotol for Touch panel (protocol ???)
  • Which WEMOS board
all IO on board must be sufficient for 4button+ LCD+ Touch panel.


I need to start with the right hardware first. Because delivery time is 4-6 week with std post

The touchscreen is a shield that mounts on arduino, not on Wemos. If you selected Wemos for wifi communications then you'll have to get both arduino and wemos, and connect them (examples in the forum).

My experience is only the Mcufriends. A much cheaper and easy solution can be to use a 4-row alfanumerics display.
thank you; I understant .
But I must use graphic screen.

Maybe Other people has an advice....

Just one more hint - the code for the display that I did in the link above used almost all the available memory in the Arduino Uno.
