Hi. I bought a popular 2.4” TFT gLCD based on ILI9341 (FIG 1)
gLCD Table ---> corresponds to ---> Flowcode Connection
----------------------------------------------------------------------------------
LCD_CS ---> corresponds to ---> chip_sel_pin
LCD_RST ---> corresponds to ---> reset_pin
But what would be the correspondence for the others FC Connections (FIG 3) ?
dataout_pin ?
clock_pin ?
dc_pin ?
led_pin ?
Some clue will be welcome. Thank you.
and it come with the little table (FIG 2) showing the function pins.
It seems that :gLCD ILI9341 - Pins correspondence to Flowcode Connections

Re: gLCD ILI9341 - Pins correspondence to Flowcode Connections
It seems your display has two options for connections, serial connection and parallel connection. The FC pins are for the serial connection. The pins D4, D5, D6, D7, WR, are for a parallel connection and you don't need those for the serial link.
For the serial link you only need clock, chip select and Data In (from processor to display). The Data Out is only needed for reading from the on-board SD card.
Check if there is a jumper or something on the display to select either serial or parallel.
I am struggling with a similar display, so far no luck.

Re: gLCD ILI9341 - Pins correspondence to Flowcode Connections
This display controller has several options to interface with other hardware. The vendor of this board has chosen to configure the controller in 8 bit parallel mode (done on the PCB, can't be changed by software, data sheet see page 26). The Flowcode component can only be used for a display configured for serial mode.
The component is not compatible with this display. You will need another component or another display.

Hi zamphy!
I use these display with Arduino mega:
https://www.ebay.com/itm/2-8-TFT-LCD-Di ... 2749.l2648
And they work very well with FC7. But remember only 3,3Volt supply and data.

Hi, and thanks to Jan”jadiflow”, & Lewis“kersing” & Jorgen”jgui” – all of you have part of the true.
* Jan - there insn´t a serial/parallel jumper specifically in this my display. See why ahead.
* Lewis – my display is really configured for a (fixed) parallel mode. There is no manner to modify it to serial mode. Good advise for new purchases.
* Jorgen – the smile man, thank you for the link for serial ILI9431 displays.
I think i´ll get it right now.
Good experiments to all.
