[AVR] how to write to 16 Bit timer value in MikroC AVR ?

asking · May 30, 2014

Hi,

I had a situation where i have write 31250 to timer1 in Mikroc for AVR for ATTiny2313. But in mikroc is not accepting TCNT1 = 31250. It asks for TCNT1H & TCNT1L. so how can i create > greater than condition with hex codes ? for I want to create program to toggle led when TCNT1 total count is greater than 32150. (1 second delay) by using prescaler @ 256 and Fosc @ 8mhz.

Please help how to manipulate condition with Hex ?

hello,

I don't know AVR but...
31250 -> gives 0x7D96 in hexadecimal , so

Code:

TCNT1H=0x7D;
TCNT1L=0x96;

2nd solution

Code:

TCNT1H= (31250 >> 8);
TCNT1LL= (31250 & 0x00FF);

3eme solution

//or you can declare a

Code:

volatile unsigned long Valeur;

Init this value in your main program
Valeur=31250L;

and use it as

Code:

TCNT1H=Hi (Valeur);
TCNT1L=Lo (Valeur);

but this consumme 4 bytes !
so i prefer 1 rst solution...
