Hy all,

I just found a bug in LPCOpen in the file lcd_17xx_40xx.c, function Chip_LCD_Init().
The clock divider is not computed the right way. The LCD controller use cclk as clock source and not pclk. So the code should be:

pcd = (Chip_Clock_GetSystemClockRate() / LCD_ConfigStruct->CLK) - 1;

instead of

pcd = (Chip_Clock_GetPeripheralClockRate() / LCD_ConfigStruct->CLK) - 1;

Best regards

PGR
