*** ERROR L104: MULTIPLE PUBLIC DEFINITIONS

We need a bit more information about the problem (processor, how is the function defined, ect.). However it looks similar to this:

My evalboard is: MCBSTR7 > STR710F2 microcontroller from ST microelectronics

my code:



HELLO.C: Hello World Example

<

// Timer3 IRQ: Executed each 10ms

void T3TIMI_IRQHandler (void) __irq

{



GPIO_BitWrite(GPIO2, 15, ~GPIO_BitRead(GPIO2, 15));



TIM_FlagClear(TIM3, TIM_TO_IT);



EIC->IPR = 1 << T3TIMI_IRQChannel;

// Timer 3 Configuration: Periodic Interrupts at aprox. 10ms

TIM_Init (TIM3); // Initialization

TIM_PrescalerConfig (TIM3, 256); // Prescaler

TIM_CounterConfig (TIM3,TIM_START); // Start Timer



// Configure and enable IRQ for Timer 3

EIC->IVR = (u32)T3TIMI_IRQHandler;

UART.c







void UART_ByteSend(UART_TypeDef *UARTx, u8 *Data)
{
while (!(UARTx->SR & UART_TxEmpty)); // while the transmit shift register not empty
UARTx->TxBUFR = *Data;
}


GPIO.c






void GPIO_BitWrite(GPIO_TypeDef *GPIOx, u8 Port_Pin, u8 Port_Val)
{
if (Port_Val&0x01)
GPIOx->PD |= 1<<Port_Pin;
else
GPIOx->PD &= ~(1<<Port_Pin);
}





Include path is : C:\Keil\ARM\INC\ST

I recommend that you directly access the peripherals (which is anyway more efficient than using the software wrappers provided by ST).
