Re: Could Espressif reach out to PlatformIO

Maybe its not very intuitive but you can edit sdkconfig.h or try to use build_flags= in platformio.ini.
This is true, but as you said its not intuitive.

Could Espressif reach out to PlatformIO

First I have to say that the ESP32 has by far been the best embedded IC I have used in over 20 years!! I have switched all projects to this IC over all other ones we have used at the company. Even projects that have no use for Wi-Fi or BT. Why? because Its just a amazing IC, and very low cost. The o...

Re: Is uart_write_bytes and read thread safe?

I am glad it cut your compile time down. Just know that the -j8 is not for everyone. On my computer its -j16.
With the cost of the ESP32, and all that it has dual cores, large flash, and the RTOS. I just don't understand why anyone would even use anything Arduino anymore.

Re: Is uart_write_bytes and read thread safe?

I rely on the example code in the esp-idf repo to understand. I agree. If they had not provided that extensive example folder with all the great examples i would not have been able to do the things i have done. Compilation is slow. I have a decent machine and it takes too long Really? A new project...

Re: Is uart_write_bytes and read thread safe?

I wish i had to time to help in more detail. I love tasks, in fact often find myself separating many things into their own things when i could have combined them. For my application. I have 3 tasks. The first one is just for receiving serial data. /************************************************* *...

Re: Is uart_write_bytes and read thread safe?

Personally, i would not touch anything serial with a stack of 1024. start with 2048 or 4096, you can always dial that in later and you get things working. There is a function that you can call to let you know to stack status. did you declare you barcode_received as a volatile variable ? I would sugg...

Re: Is uart_write_bytes and read thread safe?

I too am monitoring 2 UARTS. Both of which are on the same core and I have not had that issue. Maybe it's the way your implementing you code that is causing the problem.

Re: How to profile ESP32 application performance?

There's a configuration option, CONFIG_FREERTOS_GENERATE_RUN_TIME_STATS, that can print some performance information, but it only goes to big tasks, like main and idle. Not true, it goes for all tasks. I have been working on a "Htop" clone like thing.. Hope to post it soon. Its based on the example...

You can flash it with this.
https://www.gridconnect.com/products/es ... gging-tool

You just need 4 pins. +3.3v, GND, EN & GPIO0.
And TX0, RX0

And make sure gpio2 is not pulled up
Holy cow! how could I have forgotten them. Thanks WiFive for pointing that out.
