Hello,

I have a PCB with my first LPC project. On PCB I have a LPC1227 and connect over cabel to LPCLINK from LPCxpresso 1114.
I have a connect on a J4 connector, because I don't have small header for a J5.

When a programming in LPCxpresso, Program Flash -> Select file (myproject.axf) and then click OK.

I get a program flash message:

It is this message OK or not OK, because on my PCB with my schem nothhing.

I have on my LPC 3.3V normal connect all. But for LED blinking not working. I don't know why ?

Schem in the attachments

The flash programming log looks fine. Did you try resetting the board after programming?

If after resetting you don't see your LED blinking, I would imagine either a problem with your code (e.g poking the wrong GPIO line for the LED) or else a problem with your hardware (e.g. LED not connected correctly).

What actually happens if you click on the debug button in the Quickstart panel to actually debug your project?

Regards,
LPCXpresso Support

If I click on debug, debugging normal without Error and Warning.

I can press on Play button, but notthing.

Here is my code:

#ifdef __USE_CMSIS
#include "LPC122x.h"
#endif

#include <cr_section_macros.h>
#include <NXP/crp.h>

// Variable to store CRP value in. Will be placed automatically
// by the linker when "Enable Code Read Protect" selected.
// See crp.h header for more information
//__CRP const unsigned int CRP_WORD = CRP_NO_CRP ;

volatile uint32_t msTicks=0;

// ****************
//  SysTick_Handler
void SysTick_Handler(void)
{
msTicks++;
}

int main(void)
{
/* Enable all three GPIO blocks and IOCON */
LPC_SYSCON->SYSAHBCLKCTRL |= 0xE001001FUL;
LPC_GPIO1->DIR = 1 << 0;
LPC_GPIO1->SET = 1 << 0;

/* Generate 1ms Ticks */
SysTick_Config(SystemCoreClock / 1000);

while (1)
{
switch (msTicks)
{
case 500:
msTicks = 0;
LPC_GPIO1->CLR = 1 << 0;
break;
case 100:
case 200:
case 300:
LPC_GPIO1->NOT = 1 << 0;
break;
}
__WFI();
}
}

I don't have a quartz on pcb, and I setting in system_LPC122x.c
SYSPLLCLKSEL and MAINCLKSEL

#define MAINCLKSEL_Val        0x00000000
#define SYSPLLCLKSEL_Val      0x00000000

for Internal oscilator

my LED connect on P1.0 pin with resistor before --- anode ---- cathode ---- gnd

if I measure voltage on my LED I have a 1.88V.

On CLKOUT pin I don't have nothing just 3,04 V.Measure with Osciloscope

Supply voltage is 3,12V is OK?

Hello,
here is my solution:

Where I have a Led, pin 1.0, is reserved and with this program not working.

I change the program for 0.16 pin and then working all, here I have connect second LED.

I have a questions; how correct configure pin 1.0, 0.31 and 0.30 reserved pin? For input pin?

I would like set PIN 1.0 but I cannot.

This is my code I get error IOCON has no member, why and how then set.

[u]LPC_IOCON -> PIO1_0 = (1 << 7);[/u]
GPIOSetDir(1, 0, OUTPUT);
GPIOSetValue(1, 0, HIGH);

:~

Because IOCON has no 'PIO1_0' member :O

So look in your IOCON struct and find the correct member (name)...

Yes, R_PIO1_0 is.

But no working if I set:

LPC_SYSCON->SYSAHBCLKCTRL |= 1 << 16;
LPC_SYSCON->SYSAHBCLKCTRL |= 1 << 31;

LPC_IOCON -> R_PIO1_0 =  0xb8;
LPC_IOCON->R_PIO1_0 = 0x01;

GPIOSetDir(1, 0, OUTPUT);
GPIOSetValue(1, 0, HIGH);

What are you trying to do here :quest:

Read user manual Chapter 6.4.46 R_PIO1_0 register...

For first I would like
set FUNC PIO1.0
then set pull up
and then set digital mode.

And setting R_PIO1_0 register to 0x01 is doing that :quest:

Did you read the user manual?

Or is this a language or coding problem :quest:

OK sorry, this code is noob code.

Now I will write more transparent:

LPC_IOCON -> R_PIO1_0 = (1 << 1) | (1 << 4) | (1 << 7);

But No working.

I don't know where is the problem.
No working. On pin I have a 1.84 V.

If I run debugger and set breakpoint I have a problem with breakpoint .I get error.

If run debugging without brekapoint I have not get error.

i have a include file IO
This file working without problems for other PIN.
Just for 1.0 no.

I get warnings Breakpoint installation failed: Unknown breakpint type.

I just click on my line number two time for add brekapoint. I have a brekapint type C/C++ type

An then clikc on Debug button (spider)

I get this:

An internal error occurred during: "Launching remote Debug".
