LoPy4 - I2C - FRAM Memory - MicroPython Library
-
@jcaron , They are SMD resistors on a custom PCB. I'm not equipped to change them. I will talk with the engineer that designed my board and see if he can make the change he has a few boards incomplete (missing chips) as we are just starting to test them.

@jcaron I just double-checked to make sure and I read the schematic wrong they are indeed 10k, SMD 1002.

Hello everyone who was helping me diagnose this issue. I finally got my logic analyzer.
See if something looks odd in the serial data
here is an example of a I2C capture
code:
i2c.writeto_mem(0x51,0x3,4,addrsize=16)

@jcaron i got a logic analyzer to help me with this issue.
it looks like i'm getting an extra byte of 0x00 in there.
what do you think?
-
@Eric-Tremblay could you share what you see?
-
@jcaron i had it posted in June its in the thread bellow
-
@Eric-Tremblay Ah sorry I had missed that.
No, the message is correct. The address is on 16 bits, so takes two bytes to send.
