pic18f2550 ve glcd

[eozkantar]

arkadaşlar 18f2550 ile glcd kullanmak istedim ,simulasyonda gayet güzel çalışıyor fakat devre  hiç bir şey yazmadı osilaskopta da sinyal göremiyorum acaba 20 mhz kristal kullanıyorum configlerde mi hata var acaba  configler aşağıda,  yardımlarınızı bekliyorum.tşk....

20mhz ise fosc=HS olması gerekir

[eozkantar]

fosc=HS 
yaptım değişen bişey olmadı

[piskopatisa]

MCLR ucuna +5V vermemiş olabilirmisin

[Maxim]

MCLRE = off yapılmış

bu şekilde düzeltince çalıştı herkese tşk...

Config ayarlarını register içine datasheetten bakarak direk yazsaydık
CONFIG1L=%00100100 gibi bu şekildede yazılabilirmiydi?

Datasheetteki config1 registeri;
CONFIG1L: CONFIGURATION REGISTER 1 LOW (BYTE ADDRESS 300000h)       

7  6      5               4             3              2             1            0
— — USBDIV  CPUDIV1  CPUDIV0  PLLDIV2  PLLDIV1  PLLDIV0
bit 7 bit 0
bit 7-6 Unimplemented: Read as '0'

bit 5 USBDIV: USB Clock Selection bit (used in Full Speed USB mode only; UCFG:FSEN = 1)
1 = USB clock source comes from the 96 MHz PLL divided by 2
0 = USB clock source comes directly from the primary oscillator block with no postscale
bit 4-3 CPUDIV1:CPUDIV0: System Clock Postscaler Selection bits
For XT, HS, EC and ECIO Oscillator modes:
11 = Primary oscillator divided by 4 to derive system clock
10 = Primary oscillator divided by 3 to derive system clock
01 = Primary oscillator divided by 2 to derive system clock
00 = Primary oscillator used directly for system clock (no postscaler)
For XTPLL, HSPLL, ECPLL and ECPIO Oscillator modes:
11 = 96 MHz PLL divided by 6 to derive system clock
10 = 96 MHz PLL divided by 4 to derive system clock
01 = 96 MHz PLL divided by 3 to derive system clock
00 = 96 MHz PLL divided by 2 to derive system clock
bit 2-0 PLLDIV2:PLLDIV0: PLL Prescaler Selection bits
111 = Divide by 12 (48 MHz oscillator input)
110 = Divide by 10 (40 MHz oscillator input)
101 = Divide by 6 (24 MHz oscillator input)
100 = Divide by 5 (20 MHz oscillator input)
011 = Divide by 4 (16 MHz oscillator input)
010 = Divide by 3 (12 MHz oscillator input)
001 = Divide by 2 (8 MHz oscillator input)
000 = No prescale (4 MHz oscillator input drives PLL directly)
