I’ve been having problems installing VS2010 Beta 2 onto a selection of x64 VMWare machines (fully updated and service packed XP and Windows 7). In fact I was having problems installing it onto any of them. The error that I was getting was this: [10/22/09,07:28:42] Microsoft Application Error Reporting: [2] CMsiComponent::Install() expects the setup file for Microsoft Application Error Reporting, but the file failed verification. And whilst a google showed that others were also getting the same error it was few and far between and nobody had been given any useful advice.

Way back at the beginning of this journey I mentioned the fact that I’d quite like to be able to use some of the development disciplines that I use in my day job during the development of the firmware for my hexapod.

It’s harder than it should be, probably because I’m not experienced enough yet with assembly language not to have made some school boy errors.

The work on turning my excel spreadsheet into AVR assembler code which can move multiple servos to arrive at their target locations at the same time is proceeding well. I have the required code operating in a stand alone environment in the simulator and all I need to do now is merge that in with the rest of the code… Once that’s done my servo controller is complete and whilst I already know that there are at least two further versions in the pipeline I expect I’ll move onto something more before working on them.

The idea behind it is that with a hexapod leg you will want to be able to move the leg to a new position where the new position requires all three of the servos that manage the leg to move to potentially new locations.

I’d accumulated a pile of random nice to have ideas, some of which then necessitated some other ideas, and then there was the one must have command (the one which moves several servos to new positions over time and ensures that they all arrive at their final resting places at the same time).

My current design is very successful in doing what I set out to do, which was to give priority to the PWM generation aspect of the code.

I posted a question about my serial communications issues over on AVRFreaks and so far the answers have been pointing in the direction of including some form of formalised flow control. This makes sense. I’ve yet to decide if hardware flow control in a RTS/CTS form or software flow control such as Xon/Xoff would be best…

The symptoms of the problem were that my servo controller would suddenly to process random, poorly formed commands.

I’m building my managed XLL tool in two versions, a ’normal user’ version and a ‘pro’ version. The ‘pro’ version has additional features that I don’t feel would necessarily appeal to all of my potential users; things such as easy Excel RTD server support and Asynchronous worksheet functions. The fact that the core code is identical between the two versions has caused me a little trouble as I want to package the code in a single assembly and, although it’s all C++/CLI, I can’t work out how to build the common code in one project and link it with each of the final product projects to produce two single assemblies that both include the common code.
