Hi people,
I just work on a Dali project and trying to learn from the demo library I am getting some error can anyone PLEASE help me how to proceed.
I am trying in STM32G0
I am getting error as EXTI.Instruture undeclared i tried EXTI.Instruct but still its showing error 'NVIC_InitStructure' undeclared
hOW CAN I DECLARE THAT FUNCTIONS
void receive_tick(void)
{
// Because of the structure of current amplifier, input has
// to be negated
actual_val = get_DALIIN();
tick_count++;
// edge detected
if(actual_val != former_val)
{
switch(bit_count)
{
case 0:
if (tick_count > 2)
{
tick_count = 0;
bit_count = 1; // start bit
}
break;
case 17: // 1st stop bit
if(tick_count > 6) // stop bit error, no edge should exist
flag = ERR;
break;
default: // other bits
if(tick_count > 6)
{
if(bit_count < 9) // store bit in address byte
{
address |= (actual_val << (8-bit_count));
}
else // store bit in data byte
{
dataByte |= (actual_val << (16-bit_count));
}
bit_count++;
tick_count = 0;
}
break;
}
}else // voltage level stable
{
switch(bit_count)
{
case 0:
if(tick_count==8) // too long start bit
flag = ERR;
break;
case 17:
// First stop bit
if (tick_count==8)
{
if (actual_val==0) // wrong level of stop bit
{
flag = ERR;
}
else
{
bit_count++;
tick_count = 0;
}
}
break;
case 18:
// Second stop bit
if (tick_count==8)
{
flag = NO_ACTION;
//enable EXTI
EXTI_InitStructure.EXTI_Line = EXTI_LINE_6;
EXTI_InitStructure.EXTI_Mode = EXTI_MODE_INTERRUPT;
EXTI_InitStructure.EXTI_Trigger = EXTI_TRIGGER_FALLING;
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_Init(&EXTI_InitStructure);
DataReceivedCallback(address,dataByte);
}
break;
default: // normal bits
if(tick_count==10)
{ // too long delay before edge
flag = ERR;
}
break;
}
}
former_val = actual_val;
if(flag==ERR)
{
flag = NO_ACTION;
//enable EXTI
