I recently updated my MPLAB X installation to version 5.10.\u00a0 The compiler hasn't changed, just the IDE.\u00a0 Two surprises occurred.\u00a0 First is that my SAMD board now crashes the IDE when I plug it in.\u00a0 Only on Windows 10 on my HP tablet.

Today, I discovered that I broke my breakpoints using my PIC16 board.\u00a0 Specifically, using the PIC16f1619 Curiosity board.\u00a0 It's a relatively simple 8-bit device with a single hardware breakpoint in it.\u00a0 It appears that I've been misusing hardware breakpoints in C for a few years because of this warning:<\/p>\n

\"Software

As of version 5.10 (Nov. 2018) MPLAB X now asks you explicitly to enable software breakpoints.<\/p><\/div>\n

Never got this warning before so remained oblivious to the practical implementation of software breakpoints versus hardware ones. I typically put a single breakpoint in and let the code boot up and halt at it.\u00a0 Then, single-step to see what's going on.\u00a0 Apparently, that requires the use of additional software breakpoints.\u00a0 Well, now I know better.\u00a0 The software breakpoints add a bit of assembler code where you can't see it to halt the code.\u00a0 Time to get used to it.<\/p>\n","protected":false},"excerpt":{"rendered":"
