Hi
ich habe einen Code der eigentlich auch funktioniert.
Wollte ihn jetzt auf einen Attiny2313 schreiben, nur dummerweise reicht der SRAM nicht aus.
Vor allem das 'config dcf' scheint ausschlaggebend zu sein. Gibt es irgendwo eine Angabe wieviel SRAM 'config dcf' verschlingt?
Besteht noch Hoffnung den Code so abzuändern dass es passt?
Beim Complieren sagt er bereits bei "Dim Dig0 As Byte , Dig1 As Byte..." er seit out of SRAM.
Code:
$regfile = "attiny2313.dat"
$crystal = 1000000
Config Dcf77 = Pinb.3 , Timer = 1 , Debug = 1 , Inverted = 1 , Timer1sec = 1 , Check = 1
Config Timer0 = Timer , Prescale = 1 , Edge = Rising
Config Date = Dmy , Separator = .
Config Portb.0 = Output ' din
Config Portb.1 = Output ' cs
Config Portb.2 = Output ' clk
Max_din Alias Portb.0
Max_cs Alias Portb.1
Max_clk Alias Portb.2
Set Max_din ' cs, din, clk = high
Set Max_cs
Set Max_clk
