done and working already... for now my code gives 16 bit (E)BAM at 610hz (actually 14bit at 610 hz (1 Tcy discretisation) + 2 bits at 610/2 and 610/4 Hz and channel values are updated at 610/4Hz) my...

2 ALL...
There is one small problem with high speed BAM/MIBAM. Problem exists if u use simpler MOSFET driving scheme (or if u use slower bipolar schemes like darlinghton's transistor pairs and if...

yep... tryed it in 3 ways:
1. Simple ISR-based software PWM with floating (table-generated) pulse widths.
2. Strobing /OE of external latches (54 PWM channels/PIC16f877a) with HW PWM output...

This stuff would work for low-current balanced circuits or if don't need much accuracy and precision in result. Background? hmm.... If want get better results u should use HP Interrupts to minimize...

that's nice, but not so effective at all. interleaving could be used to get more channels at the same freq. and something else to get 100ns discretization.)))

Yep=)))
It's something like that.


btw, i had got my first shocks from electronics when i tryed to understand how my photoflash works. There was ~1000V on capacitor after trafo, but it didn't...

And I use only pure ASM code for such relatively slow MCUs, of course...

p.s. please don't expect me to do it very soon, as i have to finish some other projects too. Firstly I must repair of...

Hi there! I'm from Tallinn / ESTONIA / EU
Very nice to meet u too.

I'll show u how to increase resolution to 1Tcy later, just do not have time now. I don't like to upload or post something...

Are u blind? What u just wanna prove iterating yer silly cycles, just try to return from yer subroutine, or generate some interrupt for yer brains. Try to think. I have these devices perfectly...

What exactly do you mean saying "single problem"? u have just described 2 problems) IMHO. of course u can't operate 2 ports at the same time, but u can make somekind of "interleaving" and operate...

example... sorry it's static...

Sorry for my poor english, maybe u hadn't understood me as it was supposed. I don't want to flame here... i feel a bit tired myself and i'm way too lazy now to start explanation again. I had thought...

I have working code for 14bit 610hz BAM with 16 output PWM channels (code could be updated to get more channels with external logic if needed), but i didn't tried to resolve flicker problem with BAM...

Maximum gained speed of modulation (whatever way u make it) is only limited by speed You can change output. Normally it's 2 instruction. But U can make it in single instruction also, just clearing...

What _maximum_ refresh rates and bit resolutions have u achieved? I have developed many devices with 18F working at 10 MIPS and giving 13 bit ~610Hz (14 bit is maximum at this speed IMHO). I use ASM.

what means "LP ints"? Are u talking about jitter problem? U should update T0 then (for example) in every interrupt to avoid that. If u going to use CCP with prescalers/postscalers then will get...
