Michael, this is probably for you - but if anybody else can help please do…
I am trying to see how hard it would be to do a web based interface to the RETOOLS system. Presumably this would appear in the menu as Tools / Reverse Engineering (or some such abbreviation if that is too long). The basic screen would look something like this:
+----------------------------------------------------------------------------------------------------+
| |
| +----------+ +------+-------+------------------------------------+------+ +--------------------+ |
| | | | hdr1 | hdr2 | hdr3 | hdr4 | | | |
| | | +------+-------+------------------------------------+------+ | | |
| | Controls | | | | | | | Info | |
| | | | col1 | col2 | col3 | col4 | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| +----------+ | | | | | +--------------------+ |
| | | | | | |
| +----------+ | | | | | +--------------------+ |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| | Status | | | | | | | | |
| | | | | | TABLE | | | | |
| | | | | | | | | Extra | |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| +----------+ | | | | | +--------------------+ |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
| +------+-------+------------------------------------+------+ |
| |
+----------------------------------------------------------------------------------------------------+
The controls are just a set of controls - things that bring up dialogs for more information or perform actions. Like start/stop RE, switch modes, manipulate DBC files, etc. Left justified in the frame, and perhaps 10% of the width. Height can dynamically adjust with the text content.
The Status, Info, and Extra panes are just a dynamically updated text panes. Main code needs to be able to send text here and have it shown in the appropriate pane. Right justified in the frame and perhaps 30% of the width. Height can dynamically adjust with the text content.
The TABLE is a table. Probably 5 columns by many rows (anywhere from 20 to 200 or so). Either paged, scrolling, or just very tall. Paged is probably preferable. Would need a simple mechanism to dynamically add/update a row (identified by ‘key’ column and in sorted order), presumably using the web socket. Also need something to be able to dynamically clear the entire table. The RETOOLS code would use this to update the table in realtime (presumably over a web socket). It would be good if the table could do things like search filtering of displayed rows, column sorting, etc (all client side - something like datatables.net).
For example, look at this output:
OVMS# re dbc list
key records ms last
can1/100:0081 2 22000 01 02 03 04 05 | .....
can1/101 1 44000 01 02 03 04 | ....
dbc/DI_Signal1: 129 km
dbc/DI_Signal2: 1 km
dbc/DI_Signal3: 130 kWh
dbc/DI_Signal4: 122 Degrees
The idea is to be able to show the key, records, ms, last, and ascii dump in the main table. Then, clicking on a row would show the statistics for that message in the Info pane, and DBC signals in the Extra pane.
I can handle the RETOOLS side, but the javascript is beyond me. I also had a look at the ovms web server framework, but it doesn’t seem to be able to do the table part (yet)?
Any idea how complex this is?
Regards, Mark.
