Releases: DeeEmm/DIY-Flow-Bench
Release Candidate #9
This release is our ninth release candidate and is fully functional code that is released with the intention of peer testing. Once the peer testing process has finished and any bugs addressed, the final release candidate will become the official V2.0 release.
RC9 is a major step towards the final release. There a number of bugs that have been addressed as well as a large number of features added. Many of the changes would not have been possible without the involvement of the DIYFB community who have been been instrumental with assisting with both bug fixes and functionality.
There are simply too many changes to list, but what we have ended up with is all of the outstanding feature requests and bugs closed out.
The main focus of units tests should now be accuracy and repeatability.
Firmware Flasher
Alongside this release we have also released the new DIYFB Firmware Flasher, which provides an easy way for end users to upload the firmware. The aim here is that non-tech-savvy users can easily get a DIYFB controller up and running without having to bother themselves with IDE's, IDE dependencies and the steep learning curve that comes along with such things.
The release is packaged up with Binaries that can be used by the firmware flasher for new builds or by the GUI for updating existing installations
The binaries are compiled for the Wemos D1 R32 ESP32 which is the officially recommended board for the project. These binaries should work for ALL ESP32's that compile under the standard unmodified platformio.ini [building using release > esp32dev]. However, if you are using non-supported hardware, you may need to recompile for your specific platform.

Release Candidate #8
RC8 is a major step towards the final release. There a number of bugs that have been addressed as well as a large number of features added. Many of the changes would not have been possible without the involvement of the DIYFB community who have been been instrumental with assisting with both bug fixes and functionality.
Major features include
- Support for differential pressure style benches added
- GUI Firmware updates now possible
- Rewrite of calibration code
This release is our eighth release candidate and is fully functional code that is released with the intention of peer testing. Once the peer testing process has finished and any bugs addressed, the final release candidate will become the official V2.0 release.
The main focus of units tests should now be accuracy and repeatability.
Alongside this release we have also validated the new V2.3 shield PCB which will be available to purchase shortly.
Releases will now be packaged up with Binaries for the Wemos D1 R32 ESP32 which is the officially recommended board for the project. These binaries should work for ALL ESP32's that compile under the standard unmodified platformio.ini [building using release > esp32dev]
To be able to update firmware in the GUI, you will first need to install this release using your regular IDE. You will also need to update your index.html file as well.

V2 Release Candidate #6
Development Release
RC6 is a development release that addresses a number if bugs and adds a bunch of features. The biggest changes relate to the browser GUI and the inclusion of a data-graph tab. This allows the user to save lift data and view it in the browser in the form of a lift plot. The lift plot can be saved to the users local device as a PNG image. Lift data can also be saved in JSON format for import into other programs such as Excel.
MAF Data handling has been revised and updated and a new MAF Data file added for the Bosch 0280218067 sensor from the AUDI RS4 which supports up to 880cfm. The MAF Data files have also been updated from new source data for both the LS2 ACDELCO 92281162 sensor and the BMW M54B30 SIEMENS 5WK9605 sensors. This should improve the accuracy of both of those sensors
This release is our sixth release candidate and is fully functional code that is released with the intention of peer testing. Once the peer testing process has finished and any bugs addressed, the final release candidate will become the official V2.0 release.
The feature-set for V2 is now locked.
The main focus of units tests is now accuracy and repeatability.
Please note that the recommended board is the Wemos D1 R32. At present the system is designed to be used with DIY electronics. Work is currently underway to finalise the shield.

V2 Release Candidate #2
ESP32 port of DIYFB Project
V2.0 is a major release that is essentially a complete rewrite of the DIYFB code. The main change is that the default platform has changed from the Arduino Mega / Uno to the ESP32. The ESP32 is a faster processor that offers 12 bit resolution as well as on board DAC converters. This offers improved accuracy and speed. The ESP32 also includes data storage and Wifi support which has allowed the creation of an embedded web based user interface that can be accessed by a browser. This WebUI has completely changed the way that the DIYFB is used and offers much greater flexibility to the systems functionality.
This release is our second release candidate and is fully functional code that is released with the intention of peer testing. Once the peer testing process has finished and all bugs addressed, the final release candidate will become the official V2.0 release.
Please note that the recommended board is the Wemos D1 R32. At present the system is designed to be used with DIY electronics. Work is currently underway to finalise the shield.
RC2 is a bugfix release that incorporates the following changes identified in RC1:
Build 21082503
- #87 Wifi client network
- Corrected millivolt calc in Webserver::getDataJSON
