Hello everyone!

I've been using these VBscripts for years, and thought it was time to share them, as I've seen many people ask how this can be done easily.

For details, please see: https://github.com/HankLloydRight/FlashESP32 (This is my 2nd public repository.)

I created a couple of VBScripts to ...

It's both. Arduino has fixed values which is in and of itself a messed up idea. I am not sure why PlatformIO does not allow it because I use VisualStudio Code, and have hotkeys to get to it.


I'm using VSC with PIO and Arduino platform -- what hot keys get you to menuconfig?

I'm also trying to ...

xPortGetFreeHeapSize() is a synonym for esp_get_free_heap_size():

The ESP call is asking for a slightly different set of memory:

No, this is pretty much optimal. This way, the data is stored in internal memory which runs at the CPU clock.

Great, thank you!

Hello,

I've been using xPortGetFreeHeapSize() in my project with a LOLIN32 V1.0.0 dev board and it's been working fine.

I tried upgrading my project to a LOLIN D32 PRO dev board with the exact same code (using Arduino framework on PIO), and now xPortGetFreeHeapSize() returns values around ~4 ...

If anything, it saves you a function call if you cache those variables locally.


Thanks. Perhaps some code examples below will help explain (I should have included this first).

I'm creating a struct in memory and then calling GetPrefs() to populate that struct from NVRAM. I call this function ...

Hello,
I'm developing an ESP32 based DAC/driver for laser projectors. I'm getting pretty good performance in the main loop that runs via an interrupt (up to 70kHz). I'm also using direct register writes (instead of digitalWrite) to send data to the DACs.
But there are several user-settable ...
