Re: Increasing resolution of DTs MIBAM library?

And then you can use the dedicated PCA9685PW chip with 16 channels, 12-bit resolution, cheap and very reliable. Also the PCA9956BTW at 24 channels @ 8 bit.

Re: Increasing resolution of DTs MIBAM library?

Hah, just solved it :)
since I have output transistors, previously I was feeding their bases with output from MCU
Now I will feed their emitters via MCU, connect all bases together and connect them...

Re: Increasing resolution of DTs MIBAM library?

Well that's nice idea, but selection of pins to where you can map HPWM - is quite limited as I know.

I had another idea - use MIBAM as is, but feed outputs to logical AND gate and use built in PWM...

Re: Increasing resolution of DTs MIBAM library?

Darrels documentation says
In order to increase the resolution to 10 bits the LSB would need to be 1/4 of its current length meaning you'd need the PIC to run at 192MHz. Or you'd need to reduce the...

Re: Increasing resolution of DTs MIBAM library?

I'm using MIBAM because with 64mhz PIC18 CPU, I can have 48 independent PWM channels. But they're 8 bit. I want 48 channels with 9 or 10 bits resolution (12 - preferable) :)

Re: Increasing resolution of DTs MIBAM library?

More channels is totally a different thing from resolution as you stated on post 1...

Maybe you can do that in assembly. A bit difficult though.

Re: Increasing resolution of DTs MIBAM library?

Unfortunately, there are no PIC chips with like 8-16-32 independent PWM outputs.
Sure, there are chips like LT8500, with 48 channel PWM output, but they're way too expensive...

Re: Bitbang USB protocol?

Yes, it has been done on an AVR. See this link for the V-USB

Bitbang USB protocol?

So maybe bitbang isn't the right word, but I am wondering if anyone has attempted USB communication on a chip without integrated USB functionality. I'm aware chips like the 18F2550 include that...
