You don't need to do anything for the SPI / debugWIRE interface.  i.e. the SNAP works out of the box.   If you attach external electronics to the ISP pins it will...

Using u8g2 images on library outputs undefined
The convention is : .H for definitions, declarations, macros, ... .C, .CPP for executable code.   In practical housekeeping terms there is a good argument for large data...

Use normal port operation on unused PWM pins while Still Using Timer1
Here is an example.   Build with AS7.0 Simulator.   Set MCU frequency as 8MHz Set Breakpoints on both ISR()s View PORTB in I/O View   Run to breakpoint(s...

Use normal port operation on unused PWM pins while Still Using Timer1
It is always wise to write down your pin budget as part of your project design. You do this before you get a PCB made.   Please use pin names rather than package numbers....

Use normal port operation on unused PWM pins while Still Using Timer1
First off.   Write down what you want to do with your project.   TM1637 is not a regular protocol.  i.e. it is not SPI and it is not I2C. I suspect that your...

Analog Comparator no response
You never need to use an ISR().   Set AIN0, AIN1 as inputs.   Enable ACME / ADEN and monitor the ACI flag.   Read the ACO output bit.   But you could...

Analog Comparator no response
Go on. if ((ACSRA & 0X20) == 1) can NEVER happen.   If you want to test (ACSRA & 0x20) you either say      if ((ACSRA & 0x20) == 0x20...

Why don't you describe in English what you actually want to do.   You don't even say which Expander chip(s) you are using. Note that most chips will capture any pin-changes...

I agree.  Life will be so much easier if and when SNAP can be updated via AS7.0   Incidentally,  the PicKit4 could connect to a PIC18F458 in MPLABX IPE. And then go...

This was the first time that I have tried MPLABX IPE v6.00 It seems fairly straightforward.   I had previously only used IDE v6.00 which behaves in a similar way.  Just...

I followed the Hardware Reset procedure.   This downloaded default firmware via a SAMBA bootloader.   I ran your steps in #144. Selected dsPIC30F2020 Selected SNAP...

I presume that I just have to power-up my SNAP with J3 closed.  Then it will return to factory state.   So we just have to follow the OP's steps to replicate his problem...
