I've understood: the high speed code is suitable for 8 bit code. For 32 bit it is much slower and to increase the code execution I must increase tact frequency only. Nothing more.

You think it will be enough? This is assemble code for the mBasic compilation, not direct assembling code which is much shorter...

Who can help to transform the procedure loops into Assembler code for PIC32MZ2048EFH064 mBasic code: Sub procedure A dim i, k as longword j as word M1 as byte [40000] data CKd as sbit at LATB8_bit HD as byte at LATB CKd=0 For j=0 to 100 k=j*360 For i=0 to 100 HD=M1[i+k] CKd=1 CKd=0 next i next j end...

I mean basic sound sample from Sound library.

Yes, I've did it, everything O'K.

I try to make an emergensy sirena sound with the procedure: sub procedure Sirena() n = 500 While true While n<=2000 Sound_Play(n, 1) n=n+1 wend While n>=500 Sound_play(n, 1) n=n-1 wend wend end sub But it doesn't work, no ssound. What's wrong?

No it is too complicated.
We'll go by another way.((C) V. Lenin)

When I try to use Sound_Play in main program and in interrupt handler routine, I get message: Reentrancy is not allowed: function 'Sound_Play' called from two threads __Lib_Sound.mpas ... It is handler in main program: sub procedure Interrupt If TestBit(INTCON, TMR0IF) = 1 then ' Inc(n) INTCON.2=0 '...

Pls compare with yours. This code works continously, without "windows" between sine takts (gap 18 - 35 mS), but gives DC not more than 50%. No 100. Tsin = 150 mS (appr. 6 Hz).

What is Fsys?

Fsys=655.36 KHz, external clock.

Hi Stefan, Since I write in mBasic, I can't inderstand your code. What means "current_duty ++"? Since there is in the loop a delay (5 mS) you have not unbrocken sine, but with windows (5 mS)? What loop does "while (1)"? Belowe my code on mBasic: program A const Table_Sin as byte[256] = (128,131,134,...

PIC16LF1503, PWM library, Fpwm 10 KHz. When I start PWM in a circle While - wend I see not continous sine but 1 tact sines with delay among sine bursts approx 100 ms.
What is wrong?

In PWM lib in Procedure PWMx_Init there is a note: for enhanced mid-range 150x MCUs (PIC12LF1501) in procedure must be parameters freq_hz and timer prescaler: PWM1_Init(100000, 64). Really when I compile it I get error message: Syntax error: Expected ")" but "," found, i.e. does it means PIC12LF1501...

Did somebody implement the Brethenhame algorithm for line drawing? I try to use it but with partial success: it good draws the line in one direction (first quadrant) and draws the line in another directions either in wrong position or does not draw at all. Below the standard procedure applied to PIC...
