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.
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...
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...
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) :)
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...
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...

This is an effort to help users understand how the I2C command works by comparing it with SHIFTIN/SHIFTOUT. A serial EEPROM, 24FC1025 will be used in the example.
