PIC32MX I2C NACK ON ALL READS
Posted: Sat Sep 18, 2021 11:41 pm
Hi there,
Seems I2C module (hardware mode 100Kbit) on PIC32MX130F064D is not acknowledging any READ at all. Is this a known issue? I'm running latest FC9 version.
I have enabled Slew Rate as well as SMB options, but same issue is seen.
I have attached scope trace highlighting the issue.
The I2C READ routine is exactly the same as the one from the I2C sample FCX files we've been using for years.
Thanks for taking a look at this!
