- it would allow me to use the MCP23017 at 400MHz,
- it would be enough to read rotary encoders with an MCP23017,
- it would work using I2CREAD command.
I didn't even realize that MCS & MCSX had a Serial Communicator [blush]. Been using them for... dunno... 20+ years and never noticed. The only defence I have is I'm only an occasional user/coder.

I've been having some issues lately, not with that device specifically but with MCS Serial Communicator (or so it seems). I'm communicating with my board using simple ASCII commands at 57600 baud....
what problem is the active pullup bus chip going to solve ?
it will make zero difference to pbp's bit-banged commands and the mssp port would have no issues at 400kHz bus speed anyway [providing bus...
I would say, that for relatively simple coding routines, PBP knowledge of AI had been improved, but just when you ask something more complex, you'll get this:
Just checked and JLCPCB doesn't have any in stock. They don't have any other I2C accelerator chips (that I can see). Now I understand the gripes on the...
That graph shows a rise time of 1uS by only using a 15.8k pull-up resistor. It also shows that by using the LTC4311 you get an almost perfect waveform. It looks like this LTC4311 chip is exactly what...

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.
Re: Filtering noise from a wire
I was hoping:
Demon Yesterday, 20:39- it would allow me to use the MCP23017 at 400MHz,
- it would be enough to read rotary encoders with an MCP23017,
- it would work using I2CREAD command.
But that's too many IFs....
