Re: Problems setting up Windows Linux Subsystem with esp-idf

Thanks for the kind reply. I should have been more clear in my post. Could there not be a script that performs all the install requirements on a Linux box ? I.E. Page 69 from the great Kolban's ESP32 book Small Snippet... cd ~ mkdir esp32 cd esp32 sudo apt-get install git wget make libncurses-dev fl...

Re: Problems setting up Windows Linux Subsystem with esp-idf

I am just curious... I have just started to try to learn Linux, but so far I see how scrips are a great thing. Why hasn't some of the Linux guys, made a script that would perform all these steps. Seems to me it would be far better to run one thing that handles all this, than doing copy and pasted fr...

Thanks Mr. Kolban for this wonderful book!
An unimaginable amount of time went into that.

Re: problem trying to use Qt as my IDE

I have been using VisualGDB for my ESp32. Its an add on for Visual Studio and works great. Since you mentioned BBB, I also use it to for that as well, and many other Embedded Linux boards. https://visualgdb.com/ Tutorials for ESP32 https://visualgdb.com/w/tutorials/category/tutorials/embedded/esp826...

ESP32-WROVER/ESP32-WROVER-I Datasheet Problem

I have noticed a discrepancy on the current ESP32-WROVER/ESP32-WROVER-I Datasheet (v1.5). The latest data sheet shows 3 NC pins for the Wrover Module. Pin 27,28 & 32 on page 8 (Pin Layout). Yet, the pin description on page 9 ,shows Pin 27 as IO16, and for Pin28 as IO17. Which is correct ? I am readi...

Re: I2C crash with release/v3.0 - what's an effective way to debug this?

Just curious about this. The OP does not give enough information to actually help you. What sensor are you trying to talk to. Are you using IDF or Arduino, What ESP32 are your using. Do you have pullup resistors on the I2C lines and what are there values. You have not shared any of your code so that...

Re: ESP-WROOM-32 / GPIO16/17

Just wanted you you to know that 4.7k for a pullup on i2c is typical for a 5v rail. It's best to use a 2.2k for 3.3v.
Not saying this will fix your issue, just something to be aware of next time ;)

Re: How to get "CPU load" and "Memory Usage"

What you want is built into the RTOS, but sadly ESP has not added it in.
void vTaskGetRunTimeStats( char *pcWriteBuffer );

Re: LCD SPI & I2S - Serial & Parallel - Speed vs Ressources

@Aromo1, Kinda embarrassed to ask this, but being new to ESP32, I am looking to do this as well. I am impressed with the speeds you achieved. "full frame transfer using DMA @ 78Mbit/s ! " Might you be willing to show you code, or at least the hart of that code so that I can see how the DMA is dumpin...
