Do we have access to an assembler language reference manual for the processor that runs the ESP32? The back story is that I want to drive the low level timings of NeoPixels/WS2812s from an ESP32. We were able to achieve this on the ESP8266 using an assembly language construct that looked as follows:...

How does the project described in this thread compare (or is related to) this one: https://github.com/tuanpmt/esp32-mqtt Update: 2016-10-17: I was testing out Cesanta Mongoose libraries and they too have MQTT support. When I tested, it seemed to work just fine. Update: 2016-10-18: Tested both Mongoo...

I am finding that my default baud rate after a reboot is 115200. I am using the latest ESP-IDF images from Github and am using a DevKitC board made by Espressif to host my ESP32. Now ... I am also flashing the device at 115200. When I tried to flash it with a faster rate ... i.e 230400 that worked ....

Looking at the ESP-IDF, I am fascinated by the "newlib" component. How much of it is mapped/implemented/usable on the ESP32? As an example, the posix "pthread" APIs seem to be present. Are these usable in an ESP32 environment? Do these map to FreeRTOS? To start, I'd be interested if we had a list of...

@davydnorris, My hope is to try and eventually cover every nook and cranny. Unfortunately, I don't have any additional information on ESP32 than the rest of the community does. We are all waiting and watching keenly for news and updates on ESP-IDF and how to leverage it as best as possible. It is ve...

Right now I'm going to wait and see whether the writing can sensibly be merged into one book with consumability. If it can't, then I'll look at interest and demand and take the community interest as my guide. Step one is research and collect the subject materials and then we'll all be in a better pl...

The Book has been superceded by an ESP32 dedicated book: https://leanpub.com/kolban-ESP32 Folks, The book covering both the ESP32 and ESP8266 has been updated and release. The download can be found here: https://leanpub.com/ESP8266_ESP32 This book is free for download and you may choose to contribut...

Maybe we can use the ROM function in the mean time : int uart_rx_one_char(uint8_t *ch); That sure did look interesting, however the full description found in the uart.h found here reads: https://github.com/espressif/esp-idf/blob/master/components/esp32/include/rom/uart.h /** * @brief Get an input c...

I am running builds on a Raspberry Pi model 3 which has a quad core / 1GHz per core device. Performance is satisfactory but when I do a full build of everything from scratch, it can take 6 minutes plus. I noted that only 25% of my available CPU capacity was being used which makes sense ... it was ba...

I've reached the stage in a project where I would like to read serial data from the serial port. Given that printf() writes to the serial port, can I assume that getchar() will read from the serial port? ... later ... It appears that as of this post date, the ability to read from UART through stdin ...
