LPC 1112 LED

[lpcware]

Hi there, i have The LPC 1112 on my own PCB and associated  a LED  to Pin 22 .

This Pin 22 is Named    R/PIO1_0/AD1/CT32B1_CAP0    on the Pin Layout.

Now I want to configure the GPIO Funktion for the System.In The user Manual  there are several Modes for this Pin.

I want to create a GPIO Funktion in this Case i have to set bit 2:0  to the Value  01x for Selecting   PIO1_0  .

When I Debug there are no Errors but the LED is not Blinking.

I load the created Hexa File on my Flash Magic. without Problems.

Can you Please help me out which configuration I have to generate in my source code to make it work.

Console Output Screenshot and Source code are added as attachement.


Best Regards

Kaveh

No, you did not  J)

Must be a language problem, let's try it in germanski:

[color=#f00]Es gibt keine Pin Funktion 4 nicht !!!!!!!![/color]

LPC_IOCON->R_PIO1_0 |= (0x1<<2); // Set Port 1 Pin 0 as GPIO1_0 

Das ist Unsinn, also ist dein Pin immer noch nicht GPIO und folglich kannst du ihn auch nicht als Ausgang verwenden...

Also: im User Manual nachsehen, welche PIN Funktion GPIO ist und dann im IOCON Register setzen

i want to  know how i can set the value from pin 22 to 0.
the pin 22 is constant on 3,3 V.

the LED has a Resistor associated in Serie.

Following the datasheet only PIO0_7 can drive a normal led. Is your led a low power device?

:quest:

And did you change your errors of #4 :quest:

There is no PIO1_0 function 4  |(  This line is nonsense....

Bit 19 of SYSAHBCLKCTRL is reserved, so what are you enabling here  |(   This line is nonsense, too...

BTW: Are you using your LED with resistor or is it a 3.3V LED :quest:

Pin 19 is the SWDCLK_PIO_1 on the LPC 1112.

Funktion 4 of the IO is open drain Mode but i didnt need it.

I connected the Pin 22 to the LED an the other end of the LED to + 3,3 V.
when i want to switch it on i need to set the pin value from pin 22 to 0.
Now  i can measure with my Oscilloskope the signals and i have on bouth sides of the LED a 3,3 V Signal.

This means the µC generates 3,3V to pin 22 instead of 0.

I tried to set the state of pin 22 to 0 but it didnt worked out. there are 3,3 V konstantly and i couldnt delete it.

I wrote a new source code to set pin value 22 to 0 and the Flashing the LPC with Flash magic but this also didnt worked, the 3,3 V are permanently on pin 22..

How can i set the value of pin 22 back to 0 ?

Yes, you should do that 

LPC_IOCON->R_PIO1_0 |= [color=#f00](0x1<<2)[/color]; // Set Port 1 Pin 0 as GPIO1_0

I'm not sure what function 4 of R_PIO1_0 is in detail? Is it Bluetooth  :quest:   

LPC_SYSCON->SYSAHBCLKCTRL   |= (1<<19);

Which unknown feature are you enabling here? WLAN  :quest:

I changed  LPC_SYSCON and enabled pin 19 for SYSAHBCLKCTRL because pin 6 was wrong.
Can you please explain me how i can get access to the SYSAHBCLKCTRL  to see if it is enabled ...) .

Can you please explain me how i can get access to the SYSAHBCLKCTRL  to see if it is enabled or can you please adjust my source code for the LED so that i can test it on my PCB to make it Blink, that would be very nice from you  :) .

Look in your SYSAHBCLKCTRL: is IOCON enabled?
