My plan was to keep the resistors and accelerator chip right up against the PIC.
I don't recall seeing location requirements, but I wasn't looking for that info last night either.
Thanks, that's what I was hoping.
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...
rsocor01 Today, 12:25The graph at the bottom of page 1 of the LTC4311 shows a total rise-time of about 1uS.

Would a LTC4311 be enough...
What do you mean by active pull-ups? I couldn't see a meaningful description on google.
I'm not using weak internals, I'm using 4K7 externals.
EDIT: ... aaaaaand .......
This pops up...
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.
This is what I do to prepare PCBs...
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...
rsocor01 Yesterday, 17:53Okay, I think I might have solved this one. I didn't have the TRIS of the transmit pin configured as an output. I was under the erroneous impression the UART controller trumped control of any port...
rocket_troy Yesterday, 05:25Again, if I have it set up as another baud rate, then why is every text string in quotation marks coming through fine?

Re: JLCPCB ordering tip
I don't have the same definition of stacked and staggered as JLCPCB.
