Pay to get fritzing parts added?

He looks to be correct, despite the number of switches we have I can't find one that is 2 wire they are all 4 wire tactile (which up until now is all I had ever seen). However that is simple enough to cure, I just modified a 4 wire (which has an odd pcb footprint) to be two wire with the leads in the center of the body and the pcb foot print spaced .2 inches apart which may not be correct (every other dimension on that web page but not pin spacing nor size :slight_smile: ) Try this and see if it does what you need.

If it works then its good or at least good enough. If the motor is 9v and battery life is OK, then you shouldn't need another battery. You do want to be careful with the wiring, the ground wire to the motor should go to the mosfet and a separate ground wire from the battery to the arduino (as the motor will induce noise in to the grounds which may affect your analog measurements.

Where to find TSSOP parts

There appears to be a generic IC varient that has what looks like (at a quick glance) a tssop14 foot print. Search in parts bin for so14w will find it. Or drag a generic IC on to any view and then with inspector change to 14 pins and the SO package (tssop changes the pins to 20 which may mean there is only a 20 tssop footprint). I don't do much with SM, so someone else may have a better answer. Making a new foot print would be fairly trivial, just cut down the 20 for instance with Inkscape. Having the footprint however doesn't help with schematic or bb views (although if its a chip, generic does for bb :slight_smile: ).

It crashes continually in windows 10. It's not intuitive, user friendly or easy to use. It's a total piece of shit!

Main Fritzing Form files

Hello, I'm looking to maybe make changes to the main fritzing form but can't seem to find it in the files. Actually I only see two forms. I'm not familiar with QT at all so maybe that is why I'm having problems.

Can anyone point me to the form files where I can make some layout changes.

Thanks,

Jeffery

I'm running it on Windows 10 Pro and Home and don't have any crashing problems. Are you getting any error messages? Does it happen when doing something specific?

Ya, It could use some help in the UI being Intuitive but once you get used to it it's not to bad. Maybe ask some questions unless you've found something else you like better.

It does sometimes keep a screw up forever once screwed up. What I do (and when it hangs because of bad new parts) is clear the two Fritzing user directories (note that this will destroy all your sketches and parts so you may just want to move the directories aside rather than delete them!). They are

c:\Users\user_name\AppData\roaming\Fritzing

(which is a hidden directory so you need to have show hidden directories set in explorer) and

c:\Users\user_name\My Documents\Fritzing

(where username is your windows account name). Deleting and reinstalling Fritzing doesn't touch these directories (to preserve user data during upgrades) but if you delete or move them aside Fritzing will recreate them and hopefully work better. If it doesn't I'd suggest uninstalling the Fritzing and reinstalling in case you have a bad install but I'm thinking something is probably corrupted in the user directories.

What a total moron, no electronic design program is intuitive. This is not a MS office world where every program has similar buttons. You can have 30 years experience with $7K worth of Altuim and still not be able to jump to another EDA without watching tutorials, or else you will be fumbling around for days. Dave from EEVblog couldn't jump from Altium to KiCad without fumbling around for hours. If you are such and expert why are you even looking at Fritzing. Either grow a brain and work it out or go somewhere else.

Hi Peter

Thnks once again.
I will work on all you have said.
It will be a while.
I will let you know.
Much appreciated

I have to agree, here. There is simply no call for a message such as the OP's. If the person don't like it, then use something else... That simple.

Hi Peter
I have Windows 10, Fritzing version 9.3.
As you suggested, I loaded the updates via help/ check for updates.
Brilliant. All loaded and so I am off and running.
Its a Beta program and free, so no complaints from me.
Job done.
Once again, many thanks.

Good to hear! While it does have its limitations and bugs, Fritzing is over all an amazing piece of software. The developers appear to have thought of a whole lot of things that could be done and made provisions to be able to do them. If you have more issues, feel free to post there is lots of help available here.

Don't see such a part. Adafruit has something similar (but with the header in a different place) so you might want to see if they have a part for that in their Fritzing repository. Should be reasonably easy (as easy as making parts ever gets anyway :slight_smile: ) to make one starting from one of the existing perfboard patterns I expect. I assume you only want breadboard view for documenting?

I should have asked earlier, but I assume the 9V battery is also powering the arduino? If so in the real world you want to run a separate wire from the battery ground to the arduino ground and a second (wire from the battery ground to the Motor and Servo (both of which have motors). The current spikes from the inductance and pwm switching of the motors can cause voltage drops (due to wire resistance) in the ground circuit. That in turn will change the level of the analog voltage a bit (which may or may not matter in this case). As always the acid test is to wire it up and try it and see if it works :slight_smile: . If it works sometimes but not others then the grounds are a thing to look at (but its easiest to wire it correctly the first time :slight_smile: ). Assuming you are reading analog voltages I believe you also need to connect the arduino 5V wire to the aref pin on the arduino to set the analog reference voltage (I didn't notice that wasn't done the first time).

ICSP pads for pogo pins

I want to include a six pad ICSP programming connector on my arduino compatible board that I'm designing. I will then use something like this sparkfun Pogo Adapter to program the bootloader.

I just don't really know what I should use on the pcb design for this, at the moment I have six copper pads arranged in the correct formation and sizing. Is this the done thing? However, the problem is when I view the design in a gerber viewer, these pads appear to have solder paste on them.

How do I ensure the copper pads do not have anything on the solder paste or solder mask layers?

Also, should these ICSP pads have some kind of drill holes like vias over them for the pogo pins to sit in? ( I'd prefer them not to because I'm pushed for routing space but if they are necessary I'll put them in )

The 9V battery is not powering the Arduino.
I shall use another 9V battery for that purpose.

I have about three hours into the software and half of that was making vector art for a custom part. I found it pretty easy to use after watching a few videos, not sure if it is different on windows to ubuntu.
