Hi All,

I try to using the MikroElektronika TFT Proto MI0283QT9A. (Rev 2.0) with MEGA2560 @ 16Mhz in SPI soft mode. But the screen stay white.
I use the example code for testing for wiki web site, just remove the code with picture example for quick compiling. (in attachement) and add the Print everry start example.

Code:
I have define in code:
Const Lcd_enable_spi = True
Const Lcd_use_soft_spi = True
Const Lcd_ctrl_port = Portk
Const Lcd_reset_pin = 0
Const Lcd_pin_dc = 1
Const Lcd_pin_cs = 2
Const Lcd_pin_sdo = 3
Const Lcd_pin_clk = 4
 


But, with scope, no clock signal on portK.4 and the runing code is slow.
I have test with define PortA, same result.
For tesing the MCU, i have create this code for testing portA:
Code:

$regfile = "m2560def.dat"
$hwstack = 64
$swstack = 64
$framesize = 64
$crystal = 16000000
$baud = 9600

Config Porta = Output

Print "Start"
Do
  Toggle Porta
  Waitms 10
Loop
 

Mesuring with scope works.
I use TBX0104 for level adaptor.

What do I do wrong?

Thanks
Olivier

Thanks for reply.

But the 'communication' is for serial ($BAUD) not for SPI.

After check in ili9341.inc file, i see only xmega or m328, the lib is not tested in mega2560.
I cancel to use this lib, too much uncertainty.

Thanks
Olivier
