WebDec 2, 2015 · Hi, I solved. But now I have problem with 1 second per number. I got printing all numbers like results on display. So I need 1second interrupt per number like results Webso Timer 0 is loaded with: TH0 = 0xFC; TL0 = 0x66 Alternatively if we use: TH0 = ~(922/255); result of integer division 922/255 = 3 will be byte complemented to 0xFC and stored in TH0 Second line to fill up lower timer 0 register: TL0 = -(922%255) will negate reminder of division 922/255 and store the result in TL0 i.e. 922%255 = 154 WebTMOD = 0x01; //Working mode 1, T / C 0 is a 16-bit timer / counter TH0 = 0x3c; TL0 = 0xb0; EA = 1; ET0 = 1; TR0 = 1; LED = 0; while ( 1) { } } void T1_timer () interrupt 1 { TH0 = 0x3c; … how to use a script in anime fighting sim
