yes,i am using it on my laptop,it freezez on my desktop,i downloaded the os and ticked the mclr box and set it to 5v but it says no device detected.

hi Paul,
did you read the manuals coming with the software?

the program pickit3 wont start until i unplug the programer,then it tells me it cant find it when i plug it back in after the program fires up then get a red msg and program freezes,see pic,how do i fix it?,cheers m3vuv.

This is the best setup information I have seen. The YouTube video is OK but somewhat confusing in some places. I struggled for a while before getting the programmer to work. If I had had this information it would have been simple.

Thanks for your write-up and files.

is pickit3 sw buggy,it is freezing and having connection issues on my win7 64 pc,is that normal?.

hi Paul,
this Atu will be a bit like ATU-10. And power ist delivered through the programmer if you connect all 5 wires. You have to set the check at the GUI of PICkit like shown on the picture and select 5V…

does the pcb get powered from the pickit3 then or does it need power to the pcb as well as the connection to the programer?,hope that makes sense?,cheers+ 73 m3vuv.

Thanks is that not the same as the qrp version tho?.73.

hi Paul,
if you would like to use your ATU-100 as a ATU-50 (I name it so) you must change the windings of the coupler to 5 windings. After this you have to change EEPROM-cell 31 to "05" and cell 05 to "02". So tuning will start with more than 2 Watts and power reading will be safe up to abt. 40W (see user manual). I show you here: (green surroundings)

hi Paul,
you can read the hex from the PIC. Nothing will happen. For connecting it, look at my post #1994?

Hi all this atu-100 kit arrived today,it has all the smd bits pre soldered,i want to know if its ok to try and read or write too the pic without all the caps and torroids etc fitted,ie just the power and programing header fitted and hooked up to the pickit3,or will it blow something up?,cheers m3vuv 73.

Hi all,i have a new at-100 kit,i want to use it with a prc 320 clansman mil radio,it outputs about 3 watts in the tune position and 3 watts low power+ 30watts high power,what mods can i do to the atu-100 to use it with the radio,i have the pickit3 programer,modding it for 10watt is too low and 100 to high for tunning,any ideas?,cheers m3vuv 73.

is there a guide for programing the atu-100 using the pickit3 ,as it looks complicated!,cheers m3vuv.

Try with not connected board. Is there 5 Volts ?
Mine holds the board, not tuning of course. Only rested board.?

Hi David,

I did try that but got a message from MPLAB IPE that the circuit was
drawing too much current, although I did not measure the draw. I read
elsewhere about programming at a lower voltage so may try to see if that
works.

Hi, Matt
Is your pickit 3.5 can work properly as a voltage source ? Use it as a 5V source for supply the board.?

Hi all,

I noticed that when my PicKit 3.5 is connected to my ATU100 (EXT, PIC
1938), the 78L05 on my board gets warm to the touch - much warmer than
when the device is in it's normal operation mode.

I have seen the same effect with another PIC project of mine. My concern
is that the PicKit is for some reason drawing a lot of current and will
eventually kill the 78L05 or damage itself. Is this normal? Do I need to
do anything to protect the voltage regulator or the programmer?

Matt

Thanks all
I will look into using the EXT signal to trigger a protection circuit
