oh my god!

My ODROID-W turned up. The thing is the size that could almost fit in a matchbox. I am sold! You are right Broadcom, this little board is a threat. Good job Hardkernel.

How hard is it to program a eeprom?

Posted in cheap obsolete tech, Development, DSP, DSP Laboratory, Hardware on July 29, 2014 by asteriondaedalus

Pretty tricky if it is obsolete so no programmers around for it.

The AT17C65 is the eeprom configurator used in the eval board that the ADMCF328 sits on.

You can probably see where I picked up the fidgety RS232 approach with the AD chip and the optocouplers.

Now I know what you are thinking.  Swap it out for another chip.

Kooky idea.

Except the of the three chips that the ADMCF328 are design to work with (XC17165E, AT17C65, or 37LV65) the AT17C65 is the only one I can readily find on the aftermarket in China.  Absolutely no programmers for it though (although ATMEL have a tease page for a programmer but you can’t get it anymore, and why would you as the chip isn’t stocked anymore).

Thank you Mouser for one idea of how to build a programmer.

Although clincher came from ATMEL site along with the software for the configurator.  So, since the software seems to install on my Windoze box, I just need a DB25 parallel port – yes I said a DB25 parallel port.

Now, this goes either of two ways.  First is a USB to DB25 cable and driver, hopefully the configuration software recognises that arrangement.  Total cost $1.98.

Failing that, $6 to $11 dollars for a PCI card with DB25 parallel port and the ATMEL configurator software.

Failing that, ATMEL has also provided AVR code for programming AT17C65 so I would just code something up on my Arduino MEGA1250.

Okay, so either of 3 ways, 4 if you count no can do – which we don’t do we!

Why all this trouble?

Later chips work slightly differently and there is no guarantee the ADMCF328 will read other chip types.  Since getting a flashing LED on this little DSP chip will be proof I can program it having the right eeprom makes sense to avoid compounding the problem.

Although, the first flashing LED experiment will be against serial port boot.

Stay tuned.

PS, no Maker get out clause no way no how … I like it.

 

Wow!

Elektor do for $150 what Quantum Leaps gives away!

Although it might be closer to ArduBlock? Although ArduBlock doesn’t cover ARM etc.

Okay, so a half day fidgeting to get pyOpenCL working.

Turns out it was easy.

I have a INTEL CORE i5  CPU and you just need to install the Intel OpenCL runtime.  The SDK won’t install anyway unless 1) you have something other than VS Express or 2) there appears to be a cheat to install it anyway.  It isn’t need for pyOpenCL.

Then install the relevant exe for pyOpenCL and run that.  I installed the 32 bit version because I opted for 32bit given the raft of libraries I wanted to use. I did try installing the AMD OpenCL SDK, thinking I would need it for the Radeon, but it turned out that wasn’t it at all. Experimenting with code examples from various places it looks good.

I have copies of a couple of OpenCL books so I can dabble in the background. This is primarily for prototyping and learning the ropes of OpenCL.

I am holding off on my ARM cluster, I was about to jump in and get 3 ODROID U3 but I can wait until they bring out the U4, hopefully with an RK3288.  The ODROID XU has OpenCL (via Octa chip set) but too expensive.

I was looking for GPU cards when I thought to look closer at my current desktop.  It has a AMD RADEON HD 6570 in it, not a really hot card for gaming (apparently) but for getting a feel for OpenCL development and also playing with PyOpenCL (and OpenCL extensions of OpenCV) I think it will do.

Having trouble at moment getting pyOpenCL working.  I have tried downloading and installing both 64 and 32bit versions to get different error against same python example.  Will scratch me head a little sort this out over study breaks during the next week off before LAST MASTERS EXAM EVER!

Upgrading game pad – 2

Had to laugh.

Installed QPython on the JXD 7800 to find it includes twisted and pygame already – or at least the androidafied version  oh, and Kivy.

Can’t loose.

Will have a look at getting SPADE and potentially PROFETA working also.

Phew

So, last assignment for Master’s done save for re-reading and touching up references.  Two weeks ahead of when it has to be handed in so plenty of study time before exam.

In the meantime, some dusting off of projects in order I think.

So many, so which ones?

Might just dabble a bit with PROFETA.

I am going for a Samsung Galaxy S4 for my phone account upgrade so I can through the S2 back into the place I wanted it for – robotics experiments workhorse.

I might also get back into the FPGA bits and pieces as a couple of other toys have long turned up and waiting play:

Of course I also ordered the LOGIBONE with camera for FPGA vision experiments.  It hasn’t turned up yet since the chore of Kickstarter is getting in too early isn’t it.

Still I still have the other hack boards and now course is over with, and Telstra is sorted (so far) I can get back to the Altera video training etc.
