Hardella is an IDE for programmable logic controllers (PLC). The main aim is to provide reasonable ST (61131-3) support (autocomplete, refactoring, etc). The IDE is based on JetBrains MPS and mbeddr.

Just grab the latest version here: https://github.com/vlsi/ide61131/releases/latest

To update previous version, you can download "update...zip". For instance, Hardella-update-from-143-win.zip would update 143 or newer to the relevant release version.

Hardella's user forum is hosted at google groups: https://groups.google.com/forum/#!forum/hardella-forum If you have questions, please feel free to post a message or file an issue

In order to run Hardella, Java 1.8+ is required. Grab one here: https://www.java.com/en/download

v1.7.2: 16 June 2017

• Fixed: variable initializers are executed in PRU programs

v1.7.1: 6 May 2017

• Fixed: compilation errors when project is stored in a path with spaces
• Fixed: remove unused variables in generated PruMemoryTransfer program
• Fixed: added a compilation error when FAST_INPUTS is used in PRU1 program (only PRU0 programs can access fast inputs for now)
• Fixed: PRU_ABZ_ENCODER.initialOffset was renamed to positionOfLastZ
• Fixed: support for VAR_IN_OUT (for PRU and for CoDeSys)
• Fixed: PRU1 programs (init, memory read/write) will not run if PRU0 init was skipped

v1.7.0: 20 March 2017

• Fixed: PRU-host communication (it was broken in 1.6.2)
• Fixed: PDM_DW output was inversed
• New feature: PRU cycle statistics (duration of the PRU program, and duration of PRU cycle)
• New feature: comments after IF, ELSIF, etc

v1.6.2: 24 January 2017

• Case-insensitive mode for autocomplete
• Removed extra braces from NOT expressions
• PRU: MemoryTransfer programs was split into MemoryRead and MemoryWrite

v1.6.1: 25 December 2016

• Arguments are no longer red when replacing one FB call with another (e.g. TON(...) -> TOF(...))
• Implemented automatic updates, so updates will be small and fast

v1.6.0: 19 December 2016

• Both PRU cores can now be programmed. You can freely control 4 fast outputs and 2 fast inputs
• Standard library is improved. For instance, there's a block for step motor control, a block for ABZ encoder, and several others
• hardella.com has been launched
• EXIT statement was added, so you can break loops early
• Autocomplete menu now includes variable comments

v1.5.0: 27 October 2016
