The command line I use for test is "mloader -chip 16F887 test.hex" About the 7805 a Vin of 7.8V is fine as you have a Vdrop of 2V over the regulator. I tested this with a load of 500mA without problem (Vout = stable 5V) The only "known" problem of the 7805 is that he's getting hot due to this 2V dro...

I'm using a 9V PSU for the reason I explain above (bridge rectifier drops 1.2V) and 7805 became unstable when PSU at 7.5V input.

This will not make a difference I think because L1 is connected to VCC (5V) from the 7805. Maybe connect L1 to Vregin ?

I'm now checking the noise on the power lines and checking why this noise goes up when programming. After analyzing the Charge Pump Circuitry I have some questions (sorry for this :oops: ) 1- Do you know that when the CPC is idle there is a voltage of 37V over C18 ? 2- Shouldn't be better to add a r...

Ooops ! I was little bit to fast

Another thing I saw is that PPP_PGD_O on the side of R92 was sometimes "dirty" at low level. Didn't had time to check the output properties of RA1/RPI17.

Sorry,

Hi Ben, Just has a look at the chip U4 on the board (4053), is it not better to ground non used inputs (Z0/Z1/C) Can you explain why divide PROGABC by 2 with R8/16 ? What's the utility of U4 (switching CLK/DATA to 40p Header ???) Regards, [EDIT] Ben, I think I found a problem ! I checked the input/o...

Here I am again ! Well this morning I rolled my eyes when I used my ZIF interface with a 16F1937. Mloader doesn't recognize anymore the 16F1937 :roll: . So I tested a 16F887 with ZIF and YES it's working !!! For information when 16F1937 directly on socket of EB006 then ok. I began to scratch my head...

Your file is ok on my board
What I saw is that the error "Unknown chip type in data file" also appears when there is no PIC on board, it's like the board doesn't see the PIC !

Hi all, I tested a simple Led blinker prog with all the PIC's I have here and only one didn't accept to program (fortunately I have two of them so I crosschecked) but has nothing to do with V9 because FC6 is also unable to program it with my V7 board ! What I tested 12F675 -- OK 16F88 -- OK 16F628 -...

bobingabout wrote:I don't have any 88 or 628. I do have some 877, an 877A and 887, and some 883s, plus the 1937 that came with the EB006V9. That's my entire selection.

Also, those that you linked are the same versions of the files I'm already using.

887 and 1937 is also good for me

One remark about the power supply ! I tested now the board in USB and Extenal Power mode. The power supply is the one supplied by Matrix and is adjustable (3/4.5/6/7.5/9/13.5V). When I tested my project (True RMS Voltage sensor with 16F887/EB005LCD/EB004LED/EB007SWITCHES+breadboard) I also followed ...

Hi, Sorry I have no more 16F84A in house. Can you recompile for 16F88 or 16F628 then I can test your HEX. The driver I used for V9 is http://www.matrixmultimedia.com/resources/getresource.php?id=744 And the mloader is the one loaded with FC6.0.7 but also tested with http://www.matrixmultimedia.com/r...

Hi Steve,

Just a question, why are you passing two times the cable through the sensor ? I'm using a clip sensor and need only one pass.

Hi Jordy,

Thanks for the great job ! I have now some basements to start creating components

Personally I find that Matrix doesn't give enough documentation about this stuff and it's counter productive.

Come on Matrix

Hi Jordy,

Many thanks for your work !

I have a question about 12/24h setting. In the DS1307 component we have the HoursFormat variable in WriteTime but I'm unable to to find this item in the DS3231 component.

Is there another trick to change this setting

Regards,

Hi all, I'm not sure of this statement but today it started working when I used Matrix power supply switched to 9V. First times I set it to 7.5V power and also to USB power. Is it possible that the V9 board turns unstable when not powered enough ? I'm working this weekend on two projects so I will f...

Mine is installed with Matrix driver and the board is connected directly to mainboard without hub.

I will check when I'm back at home if WinUsb devicedriver is also installed.

Hello, The board is working great here on my Windows 7 64-bit setup and in fact on every machine in the building but I have reports that on some systems the Windows Update driver is overpowering our driver every time the computer is connected back to the internet. If you have the EB006 v9 hardware ...

Hi Ben,

Nice to have some feedback

Do you plan to use an alternative to winusb ?

Regards,

Hi all,

Thanks for the feedback, I will try to contact the staff.

Hi Jac,

Well like you can see I have a lot of HID interfaces. I'm only using one mouse and one keyboard from Logitech .

What do you think ?

Regards,

Hello, I tried something today, I programmed a 16F1937 with a simple 500ms blink led on RB0 with my EB006-V7 board. Then I switched from board to the V9 and tested the ICT function and it works ! ICT.jpg So I suppose my V9 board should be ok ? I'm more and more convinced that the problem comes from ...

Hi all,

Worked some hours this weekend without success on V9 board

Who is working at Matrix on Mloader ?

Is Mloader and V9 board working without any problems on your systems ?

Regards,

Bad news ! :( I had to restart my desktop for windows updates and now my V9 doesn't work anymore ... It's really disappointing , I tried five times to uninstall/install the driver without success, even on my laptop it stopped working. More and more I think that the on-board PIC24 is doing strange th...

Good Morning ! This morning as test purpose I did the following : 1. Test my V9 board --- ok :) 2. Install again the V7 driver and retest V9 with mloader -- FAILED 3. Uninstall V7 driver and test V9 board -- FAILED but with a "Unknown chip type in datafile" 4. Uninstall and reinstall V9 driver with ...
