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...
If you keep messing up the "comma-separated" file prep like I do (the SAVE feature from Open Office is not smooth), consider using a script if you are I.S. savvy.
If you connect a logical analyzer to the serial lines, you know for sure if data is being transmitted or not. That would have saved you a lot of time. I always put in my PCB designs a testing point...

It's almost Olympics time... so here's a topical program using PBP exclusively (no embedded Assembler) to give you a Stop-Watch with 1/100th Second Timing (yes that's 0.01 of a Second) and gives you REAL-TIME display on your LCD. Now you can do your own timing and challenge the official time...
The program demonstrates using TMR1 in BACKGROUND (multi-tasking), uses PICBasic Interrupts, and accounts for the fact that PICBasic doesn't respond to those Interrupts immediately. There's also a set-Up CALIBRATION menu item, so you can adjust and calibrate your timer to an accuracy of 360mS per Hour.
How does it do all that? Better download the PDF and find out...
