rf24 driver library locking CPU while transmitting
Log from wireless microphone digital
I did some more tests just with I2S passthrough and the decimation. The deciamtion works fine even when doing some Serial.print(samples,BIN); to check samples are coming are going.The millisecond I enable the rf24.send(samples, len); to send the 48 byte...

Resetting Bug
Log from OSHWatch
I have some further thoughts into this resetting bug; I've realised the watch doesn't actually report a brown-out reset, and it ONLY happens after leaving the watch in sleep mode for an extended amount of time (>1 hour). Furthermore, the scope trace...

Firmware source
Log from Color Open Source Smartwatch
I have uploaded my firmware source:https://github.com/Emeryth/sma-q2-ossIt's based on nRF5 SDK 11.0 and FreeRTOS.I have also uploaded my fork of Gadgetbridge that lets you connect to the watch:https://github.com/Emeryth/Gadgetbridge

Second thoughts about the SDK hacking approach
Log from Bare metal second core on ESP32
Why didn't it work? I've been wondering why my SDK hacking attempts did work so poorly. But, after thinking a bit about it, it should have been obvious from the start: Synchronization functions heavily depend on the scheduler! I wanted my bare-metal...

multithreaded thread safe re-entrant libraries
Log from wireless microphone digital
Soon into starting to use freeRTOS to try and tackle the timing issues i'm possibly having with I2S SSC and RH_R24 radio ( driver librarys should be multithreaded, thread safe re-entrant libraries ) are needed to use freeRTOS. I ask on RadioHead forum...

ESP32 RMT peripheral for radio remote control
Details from ESP32 RMT peripheral for radio remote control
This project intends to provide a tool that we consider might be useful for ESP32 hackers and developers: a Command Language Interface (CLI) application built for ESP32 using the Arduino(c) IDE, using the ESP32 RMT peripheral to transmit and decode...

The fun begins
Log from On Air
So far on my blog I have documented the initial work for my Train all the Things project. With the initial research and setup done I'm off into the unknown. I got my ESP-EYE last week and I've been able to setup the esp-idf tool chain. So far I'm liking...

Smart Chain Puller
Details from Smart Chain Puller
The brain of the Smart Chain is an ESP8266 NodeMCU board. It uses the ESP8266_RTOS_SDK with the esp-homekit-sdk. I chose this framework because I wanted the features of FreeRTOS, and I have used Apple HomeKit before. However, at some point I would...

Open firmware
Log from Digitabulum: The last motion-capture glove
Digitabulum's firmware is open source. There isn't much to it right now, because we're still grappling with boiler-plate hardware drivers. The firmware will be using FreeRTOS as its core scheduling and threading model, with ManuvrOS as the messaging...

Progress so far...
Log from STM32L0 Watch
Currently, I would say the hardware is complete. I'd like to perhaps get the watch printed in a clear resin so people can see the inner workings of it. Black is still the sexiest.My files are a mess. My code is a mess as well. There are some FreeRTOS...
