math functions for 89c51
CMOS, do you mean like this:
void sendhumidity_data()
{
char humidity;
long int humidity1; //I tried int , long and long int.
humidity1 = (((6785)*(150))/10000)-27;
//humidity1 = ((6785*2)/10000) + 20;
humidity = humidity1;
bin=(humidity/10)...
keil bcd to 16 int
Hi
I am using keil to program my 89C51 using C language, and I am trying to work the following equation.
humidity = (0.6785 * (ADC_value)) - 27.1
note that ADC_value is giving correct values.
But when I build my program it will give me 8 warrnings and when I debug my...
Re: Can you help me with Power down modes plss, I realy need
What do you mean by waking up 1200 times ?
I saw some examples that used a loop with a counter and once the counter is invoked the interupt will occur and the program will leave the loop and thus the micro will wake up. Though I...

Hi Kurenai_ryu
Thanks for the reply. So in other words I can't make the micro wake up automatically while on power down mode.
What kind of external interupt can I make to wake up the micro while on power down mode?
I am asking...
Hi
I programmed the micro to read some analogue data from sensors and switch some relays and send data via Uart to a RF module .
All I need now is to set the micro in Power down mode since I am running the system on solar and batties.
I set the PCON register to
PCON |= 0x02 // sets the...
