Doing some checking on Microchip website looks like all 32 bit PICS are 3.3v so assume I cannot use EB006

Okay assuming I do the programming via PicKit3 what should I look out for in terms of using newer PIC's that would still work with EB006 Could I use a PIC32MX250F128 for example. ( 28pin) Any suggestions on new PIC's I could use that made use of all 40 pins as I would be interested in programming in...

Just spent an interesting the morning at Microchips Winnersh HQ learning about MPLAB-X Was wondering if I could give things a try with my oldie E-Blocks. My EB006 is quite old - version EB006-00-6. The data sheet mentions ICD2 connector. Would this be enough to allow it to work with a PicKit2 or Pic...

I am thinking of bring my old EB006-00-6 development board out of retirement. I used to use MPLAB to compile Assembler and then download with PPP. 1) Where can I find the latest version of PPP ? A number of versions not hosted by Matrixtsl seem to be infected with malware. 2) Has there been any inte...

The matrix supply is is set to 7.5volts as per the instructions.

Just tried 9 volts and SUCCESS!!!! Thanks very much

I will dig out my meter and check the 7.5 volt setting

I have a problem in that the expansion board does not provide enough power to drive USB devices like a Wifi dongle. My plan was to take my Pi and E-Blocks to a Raspberry Pi meeting and access via my iPad, but when powered though the EB380 expansion board there is not enough power to drive the Wi-fi ...

Hi Keith, I believe this might have been done on purpose A: To prevent students from taking the SD cards B: The files on the SD card (as far as I am aware) are not accessible outside of the Linux OS running on the Pi so once the OS is installed and running there is little need to remove the card C:...

My board has arrived and just read through the instructions for assembling the case. Find it very difficult to believe that the case APPEARS NOT TO ALLOW you to remove/insert the SD card of the Pi. What sort of non design is that. VERY VERY disappointing.

Benj wrote:Hello,
With the EB385 attached you can power the pi using either the standard USB supply or the DC supply socket on the EB385.

But thats not what I want to do. I want to power the Pi via its power input, but with the EB385 attached but not in use. Is that possible?

I have an EB385 on order and have the following question. If I have the EB385 phyiscally attached but not in use, can I still power the Pi directly rather than through the EB385. The reason I ask is my Pi will spend 90% of its time on my desk running einstein@home and the power cable is threaded thr...

So did more that two user components make it into Flowcode V5?

Are you guy's following what is happening with Raspberry Pi? Would be good to have the equivalent of a Gertboard that allowed one to use E-Blocks with a Raspberry Pi. Even better to have Flowcode supported on one. I have posted in their forum also http://www.raspberrypi.org/forum/educational-applica...

Out of Interest how thick is the backplane BP232?

The datasheet link still appears to be broken.

"Also seeing as we can currently do anything that the MBED can do using an ECIO and E-blocks there seems little reason for tackling this at the moment." TOTALLY misses the point. mbed are going to sell orders of magnitude more devices than ECIO and hence would be a bigger market that you could explo...

"Unfortunately, we do not support the ARM processor used on the MBED module." Well I think Matrix Multimedia are missing a trick. I think mbed and Arduino platforms are going to attract a much bigger following than Matrix Multimedia with their own products. Creating products that marry mbed and ardu...

Better Idea. How about Matrix designing a board that supports various E-Blocks and can have an mbed plugged in as a daughter board. Make any necessary changes to Flowcode to support. Then sell loads of the boards, E-Blocks and Flowcode to the mbed community. Please can I have a free sample for comin...

Is there anyway an Matrix Multimedia ARM Board could be used as part of a mbed system see http://mbed.org/? It seems to me that there a number of "Open" like microprocessor developments like arduino and mbed and it would be good to see such systems have the ability to take advantage of E-Blocks and ...

Being new to Flowcode I have some newbie questions. 1) I see in Chip you can set the oscillator to XTAL, but how does Flowcode know what crystal you have attached? 2) I notice that some components add C code that may not get called. Is the complier clever enough to eliminate code that is never calle...

Okay now understand - I will have to eat crow - I see to read a register you first need to write to the register. I just checked my code and do seem to be doing writes first. So long since I wrote it I had forgotten. I am sure I got my info from some microchip documentation. Like you say its quite a...

Hi Harry Sorry still confused. When reading the software version, It looks like you start with a write to register 0. ( your label has 0x02). What is the purpose of this write I cannot see from the documentation. Surely you could just do a read of register 0 to get the software version. My assertion...

As the Backplane is metal should one use stand off's to avoid shorts?

Please remind me of the spacing and hole diameter.

I tried downloading the pdf file, but the link was broken.

Thanks

Thanks

I think it would be great if one just needed to add a single macro in a component to make a program function call to a PC.

Keith

Would it be possible to consider adding a RPC remote procedure call request to the TCP component. If this could be done then this would be a great way of combining PIC with PC's. i.e. The PIC does the hardware interfacing and then makes a RPC call ( like a subroutine call ) to the PC to do some numb...

I tried to use this program to understand the I2C component and must admit it had me confused.

When reading the software version why is 0x00 initially written? ( The Program displays Register 0x02) very confusing.
I cannot see anything about this in the SRF02 technical specs.

Thanks I will give the demo version a go. Is it possible to include assembler code? Some of the functions I need have specific timing requirements which are more controllable in Assembler. i.e. I can just use picloops to give me code for an exact delay. I am not sure how I would do the same in C Keith
