Question about Inchworm+

[Quan]

Hi I have question for you...

I have inchworm+ it looks good when I plug it in it turn on even if switch is on or off...

Is this supposed to happen...

Thanks...

 

[Quan]

I plug ed in 9volt 1000milliamp adapter...

multimeter is broke I dont know what it is actually...

Is this ok...

Look at the schematics.

You will see that the switch controls power to the +5 (target power) on the ICSP connector. The LED is telling you that the Inchworm has power. It is OK.

Thanks...

I was nervous...

I look at schematic and see that it connects power to microcontroller...

How does target get 13 12 volt...

 

[3v0]

The inchworm assembly instruction do a good job of covering that in the text. The max232 chip converts 5V to about +15V. A series of diode drops are used to get it down to where VPP should be. The 2nd switch is used to select between 12V and 13V. Note that the white lettering on the PCB is backwards. The 12 and 13 are interchanged.

There has been several thread where people needed help getting theirs working. Most are for the non+ version but it may be a good idea to read them. I am still quite willing to help but that may be faster.

 

[Quan]

So 16F 12F gets 12V...

18F and dsPIC get 13V...

Am I right...

It is the other way around. From the assembly instructions...

...and U3 a RS232
level converter with built in switched capacitor voltage doublers.
VPP > 12V is generated from 5V using the ST232s’ (MAX232) own
internal voltage doublers. Diode D5 and capacitor C6 act as part of a
voltage multiplier circuit. In a lossless circuit there would be
approximately 15V at the cathode of D5 but because of voltage drops
both internally to the ST232 and across D5 (approx 0.7V) the voltage is
actually closer to 14V. D6 rectifies and C12 filters the voltage down to approx 13.5 VDC, Q4 will reduce
VPP by another 0.6V. S1/J1 on the Inchworm+ will allow for setting a slightly lower VPP (using D7 as a
0.7V drop) for dsPICs & 18F PICs.

 

[Quan]

Ok...

So I connect the 10 pin header to target chip and program and it doesnt need its own power source?

Inchworm+ provides the power for it?

On my inchworm, the voltage is correct by the switch...

What program should I write first...

 

[Quan]

I find program... Called Hello World for inchworm ICD2...

I am use 16F628A I folo directions of sheet?

I am excited... Cant wait to program...

Krumlink is my email buddy from michigan, I from west coast...

He says sorry, he was mad... I help him out...

He is doing this project along with me...

Thanks...

 

[Quan]

I wrote the code in and follow directions...

This pop up under MPLAB IDE 2

What to do?

I need your help please...

Thanks...

You have to put tabs before almost all program lines except labels or comments.

Also make sure your FIFO buffers are off or it will give you connection errors.

You have installed the C18 compiler and set the asm toolsuite path to point to the c18 assembler.

To fix this go into "Project/set language tool locations" click on the + next to "Microchip MPASM Toolsuite" then on + next to Executables and then on MPASM assembler. The path at the bottom will say something like C:\C18\.... Browse to the correct location - on my machine it is C:\Program Files\Microchip\MPASM Suite\MPAsmWin.exe.

It should now build correctly.

Mike.

Krumlink is my email buddy from michigan, I from west coast...

i thought something smelled fishy about this 'new' member...

how do i turn off fifo buffers...

from the windows xp desktop

For COM1 you would do...
start>control pannel>system>hardware>device manager>PORTS(COM and LPT)
>Communication Port (COM1)>Port Setting>Advanced

Then make sure "Use FIFO Buffers" box is NOT checked.

 

[blueroomelectronics]

The FIFO buffer window looks like this. Uncheck the buffer box, COM1 and COM2 work best.

It says I need write priviledges for me to change it...

What do I do...

I changed the programming language location so it works now...

I still cant get it...
