Hi all, Stack overflow - Bobby Baskar - Oct 15 11:43:11 2009
Dear All,
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 Can anyone help me in solving th=
is problem in IAR compiler.
=A0
The stack 'Stack' is filled to 92% (74 bytes used out of 80). The warning t=
hreshold is set to 90%

Re: Hi all, Stack overflow - Michael - Oct 15 12:09:15 2009
First, it is not necessary a problem, it's just a warning as it hasn't over=
flowed yet. You need to know what the stack is and how it is used to unders=
tand what the warning means and if you need to do something about it and wh=
at that would be.
But to answer your question:
You have a bucket. You have someone watching it. He gives you a warning whe=
n it's 90 percent full.
The watcher is sending you a warning because it is 92% full. What do you do=
if you don't want him to give you a warning?
Either increase the stack size (override the default 80 bytes), increment t=
he treshold (or shut him up) or decrease the stack usage. You can do the la=
tter by moving local variables to global ones, using smaller variables like=
chars instead of ints where allowed, or reduce function call nesting. Each=
time you call a function, local variables from the CALLING function are pu=
shed into the stack. IAR has a very useful option where you can see which f=
unctions are presently on the stack (you can see the stack 'tree'). Don't r=
emember where it is. Maybe View -> Stack?
Anyway, you first need to learn what the stack is.

Michael K.

Is there a way to set it to auto? Mine just says choose a number between 0 and 65535.

Enabling analog inputs of Adc10 - Abimbola Jubril - Oct 16 10:37:15 2009
Dear all,
Please, help me out. I modified the code that came with the ez430-2500rf but it seemed the input is still behaving as digital input. It only moves from high to low and low to high.
find below the clip of the code:
************************************************************************************
uint8 msg[64];
__no_init volatile int dataloc[16] @ 0x200;
void ADC10_AcquireData()
{
ADC10CTL1 = INCH_7 + CONSEQ_3; // A7/A0, repeat multi channel
ADC10CTL0 = SREF_0 + ADC10SHT_2 + MSC + ADC10ON + ADC10IE;
ADC10AE0 = 0xFF; // P2.0,1,...7 ADC option select
ADC10AE1 |= 0xF0;
ADC10DTC1 = 0x20; // 32 conversions
for (;;)
{
P1OUT |= 0x01; // Set P1.0 LED on
ADC10CTL0 &= ~ENC;
while (ADC10CTL1 & BUSY); // Wait if ADC10 core is active
ADC10SA = 0x200; // Data buffer start
ADC10CTL0 |= ENC + ADC10SC; // Sampling and conversion ready
__bis_SR_register(CPUOFF + GIE); // LPM0, ADC10_ISR will force exit
P1OUT &= ~0x01; // Clear P1.0 LED off
}
//****************************************************
msg[0]='#';
// msg[9]= '#';
for(int i=0; i<8;i++){
msg[i+1] =(dataloc[i]>>2)&0xFF;
}
}

What do you mean by that? If it's an analog input, it doesn't 'move' anything.
How are we supposed to help if you don't tell us anything? You don't say what you modified, not even which pin you chaged nor from what to what you changed it.
If you want help, make it easy for people to help you.
