Yeah, I've scanned through the different files changing them to 1, it still doesn't work...

Re: Undefined Reference to "uxTaskGetSystemState" Upon Any Attempt to Use.

Thank you both for your answers. Do I have to install ESPIDF to access these options?

Edit: I tried changing the config file manually, that didn't help.
(tried setting CONFIG_FREERTOS_USE_TRACE_FACILITY to 'y' , '1', and 'true' and then recompiling in arduino.)

Undefined Reference to "uxTaskGetSystemState" Upon Any Attempt to Use.

Hello! I have just started freeRTOS and I wanted to do some debugging of my tasks. I wrote a function to display all task states using "uxTaskGetSystemState()" but any attempt to use this function results in the following error: C:\Users\...\AppData\Local\Temp\arduino_modified_sketch_317958/sketch_n...

Re: Making use of the built in BASIC interpreter

Ok, thank you!

It is a bit sad that the built in one is not available for use, but 4kB out of 4MB is not much :P

Making use of the built in BASIC interpreter

Hello! I just accidentally stumbled upon the ESP32's built in BASIC interpreter when my code failed(?) to run. I found it to be very functional and could possibly be useful in my projects. Is there a way to run this interpreter from inside a sketch? To continue on that, would it be possible to imple...

ESP32 Hall Sensor - Not very sensitive?

Hello! I have a bit of an issue. When running the Hall Sensor test, the values returned are very small (about 12), fluctuate a lot (±6), and do not change much in the presence of a large magnet (20 when 1cm away, 60 when in contact). Others are reporting values around 5,200 which vary a lot when aro...

Re: Issues Using Multiple SPI Buses w/ HW-CS

Hmmm, that might be a challenge! I do not have an oscilloscope, how else could I test it? I could give some more details, though! If I change the SPI speed, the screen works fine. The SD card initializes, reads properties (Name, type, size) but then fails to read, write, rename, or open files. If I ...

Re: Capacitive touch.

As @tele_player said, this value varies with the capacitance of the touch pin. It will range from about 2~64, with lower numbers meaning, counter-intuitively, more capacitance. To make this work as a button, you could do something like if(touchRead(T0)<15){//True if touched, false if not. Serial.pri...

Issues Using Multiple SPI Buses w/ HW-CS

Hello! I have two libraries that run off of the same MISO, MOSI, and SCK: A ST7735 TFT library that I wrote and the built-in SPI SD library. With some modification to both, I was able to get them to run side-by-side. However, for some reason, changing the SPI speed or setting "useHwCs" on the LCD li...

Re: DAC Max Current?

Maybe, but there still has to be some amperage! I thought the DACs were just (essentially) 8 outputs (with different resistances) in parallel, meaning they'd have quite a lot of current to give! I don't know though, and even if I were right, there is absolutely no documentation on which DAC is used ...
