Hi all,
I am using lpc1764 with FreeRTOS.I am using LPC17xx.h file from FreeRTOS Demo code(1768,redsuite).After Power up,i have read PCONP and its value is 0xe.but as per user guide reset value is 0x03BE.Any ideas.?????
GPIO's functionalities not working properly.Which means Couldn't set GPIO pins(cofigure as GPIO,output and set to high).It shows always zeros.any idea???

In FreeRTOS demo code,i have found that bit 15 of PCNOP is set(as per user guide17xx this bit is reserved).After set 15th bit, GPIO functionality working.(could able to set GPIO to high).But In my code, If i set 15th bit of PCONP and read means that 15th bit is set.But another place if i set 15th bit and read that bit means that bit is not set.
I dont know why?????

Please share your knowledge???If i made any mistake please guide me???

These are basic feature of any LPC.Is the LPC17xx.h file is correct??(Freertosdemo code ..lpc1768/redsuite)???
FYI: UART,timer etc are working fine.

Thanks,

FYI: UART0,12,3,timer1 etc are working fine.

Hi all,
At powerup, if i read PCONP register value means,it gives me 0xe;Is it correct?????

This is the gating Issue for us to go for lpc17xx series????

Is there any NXP guys,please reply me???

There is issue in PCONP and GPIOs in LPC17xx(compare my observation with lpc17xx user manual info).

Thanks

Hi

I don't think that the LPC17XX user's manual is correct due to the fact that it gives the reset state of this register as 0x3be at one location and as 0x042807de at another location.

The bit to control ports is not defined (0x8000) but it needs to be set for the ports to operate correctly (same value as for LP23XX series).

Regards

Mark

Mark,
Thanks for your update.I have set 0x8000 into PCONP.Then GPIO's functionality working fine.But I have written some valid value into PCONP register then i have read it.It gives unexpected value???Is it expected???

Thanks,
