Comfile Technology A.K.A. CUBLOC

Has anybody dealt with Comfile Technology recently? They produce and sell a useful range of 32-bit Floating Point micro controllers but:

1) Their support forum has no messages later than 2014

2) Email messages to both sales and support in the USA get bounced back with error messages

3) There is no reply when I email their head office in Korea.

Have they been taken over or is the company dead, killed by an abundance of Arduino and Raspberry Pi?

It looks like they released an update for their development environment earlier this month, so it might be taking its dying breaths. Interestingly, there's no news articles about it either... talk about fading into obscurity

Why expensive floating point unit matters in uC? If you really need one, go get an ARM w/FPU, since they are massively manufactured, they should be cheaper than obscure uC designs.

They most likely are using ARM microcontrollers, they're just packaged into modules and running their proprietary software.

They use ARM processors in their modules but they're programmed in BASIC rather than C or C++, they also have a useful range of LCD screens with additions to the chip software to directly talk to them.

As for the need for 32-bit floating point math, if you want to work out the tuning word for a DDS chip then the formula is
(2^32 / Clock Frequency in Hz) x wanted frequency in Hz, not easy to do in eight bits. PICAXE have a 32-bit FP coprocessor but it's a lot of messing around and isn't too well integrated.
