LCD controller LPC2470 does not works ?, LCD controller LPC2470 Опции

[Michal755]

Is somebody who has experience with LCD controller in LCP2470 ? LCD power up sequence no set signals LCDENAB/LCDM and other to "high" (set LcdEn bit within the LCD_CTRL register) , when set LcdPwr bit within the LCD_CTRL register, LCDPWR signal is not "high".

Check if these pins are not shared between different controllers ( may be PIO and LCD controller? ). If so - switch ports connection to LCD controller.

I don't think - I just read docs:
Look at datasheet - http://www.standardics.nxp.com/products/lp...eet/lpc2470.pdf , page 16. Pin 154 shares P2[0]/PWM1[1]/TXD1/TRACECLK/LCDPWR
Next read user manual at page 178:
http://www.standardics.nxp.com/support/doc...ual.lpc24xx.pdf
PINSEL4 - pin function select register
PINSEL4[1:0] = 00 <=> {default at reset, GPIO Port2.0 },
PINSEL4[1:0] = 11 <=> { LCDPWR and don't fotget about PINSEL10 }
For other pins - look corresponding PINSELX register.
