@SNG if you check on top of the General Purpose Registers bloc (in PIC18 Simulator IDE), you have a little box named "Real Time Duration" (expressed in microSeconds). This is real time duration of your code if it runs on real PIC hardware. When the leds toogle, you can easily see that this duration...

thanks, came already to the same conclusion, after running the simulation with 'PIC18 Simulator IDE' for a while, suddenly the LEDs turned off... so that means Delay_ms(500) is working... I know the simulator timing function is far from realistic but this is ridiculous... in 'normal speed' in the PI...

have also changed the port in the init to LAT, same result

removed double post, mouse is getting overheated

1- Which version of MikroB are you using? 2- Could you post the whole generated ASM code please? I use currently v4.60.0.0 program LEDTEST main: CMCON = 0x07 ' turn off comparators ADCON1 = 0x0F ' turn off analog inputs PORTB = 0 TRISB = %00000000 PORTC = 0 TRISC = %00000000 While TRUE LATB = 0xFF ...

it's much easier to help seeing some code than theorising on possible causes... Code is very simple program LED main: CMCON = 0x07 ADCON1 = 0x00 PORTB = 0 TRISB = %00000000 While TRUE PORTB.1 = 1 Delay_ms(5000) PORTB.1 = 0 Delay_ms(5000) wend end.

after a long while I started again with programming PICs, think I am very very rusty my code hangs on delay_ms (test it in mBasic and mBasic Pro)... I use the PIC18F458 with a 20 mhz crystal, in project settings I put it on 20 mhz and only turn the oscillator on HS enabled... for the rest nothing, j...

http://www.rigolna.com/ Thanks for the link! That are the oscilloscopes I have seen at Sim Lim Towers.... also interested in the waveforms... They are very solid build and reliable what I have heard from the shop... at least they feel like and not as the usual Chinese stuff.... quality is improving...

Yeah, poor quality Chinese parts can be a problem - especially here in Thailand. The problem is made all the more confusing because there are now some extremely good products coming from China; we bought some Rigol (proudly Chinese) test equipment earlier this year and it is just superb, great valu...

You can better visit SIM LIM TOWERS, opposite of Sim Lim Square. Is the heaven for an electronics geek.... Indeed. I am familiar with both shopping malls, although Sim Lim Towers has become very expensive over recent years and, generally speaking, it is cheaper to shop online. Unfortunately I don't...

Thanks for explaining. Problem is that I need a PIC with CAN support, so I've to use the P18Fxx8(0) series I'm afraid... don't want use SPI-CAN, it is slower and love to keep the design small as possible. YES I did read the datasheet but chapter 9 instead of chapter 20. Think to find it within the I...
