Hi all,
In my attached Eagle files i.e. schematic and board, I've got some unclear aspects feedback from my boardhouse in relation to my my ground plane and ground path.
1st issue: Firstly with the ground plane I'm being advised by my boardhouse that my ground planes and tracks are too close...
Hi all,
I’m aware this must be a well covered topic on forums but having read a lot of links I seem to be stuck. Essentially I've got my brd file which I routed using a combination of manual routing and using the auto-router. I have a couple of remaining airwires and I’m wondering the best way...
Hi Klaus,
Thanks for the reply. I would not mind you sending me the library for passives/inductors. My email is bgedsa12@gmail.com.
Regarding the caps I'll look into the caps you have suggested.
As for the inductor I’ve found the PE-52629 inductor...
Hi Klaus,
Thanks for the reply. Yes the board house guys have been very helpful especially considering I'm of a junior level in terms of my electronics and I'm all alone on this project.
I think I've found a capacitor that fits my needs based on the section of the datasheet you refer to i.e. ...
Hi all,
I'm developing a PCB in Cadsoft Eagle as seen in the brd and sch files as per the links below:
Eagle schematic file: https://sites.google.com/site/bgedsadata/EASYDAQ-XBEE%20v4sch.sch?attredirects=0&d=1
Eagle board file...
Hi all,
I'd like to use freerouting.com's program to perform autowriting. I'm able to create the DSN file successfully after using the following .ulp file eagle2freerouter.ulp which I downloaded from the official Cadsoft downloads page.
I'm successfully able to successfully perform autorouting...
@Klaus:
Thanks for the reply. I'll go for the voltage divider approach similar to the very 1st diagram on this link - https://learn.sparkfun.com/tutorials/voltage-dividers/all.
Essentially I'll test using the values of R1 and R2 as 1700ohms and 3300ohms respectively. Ideally my understanding...
Hi all,
As per my schematic below and my breadboard set up I’m already executing serial communications successfully between the PIC18F2580 and the ETRX357HR Zigbee module but I’m being advised by my board house there is the potential for serial communication issues to arise due to the differing...
Hi all,
I've looked further into the use of the switching regulator specifically the LM2575-N to deal with the heat dissipation problem as outlined in my first post. Please see my proposed approach here (Apologies if bits of the diagram are not that clear. I drew my approach by hand before...
Hi all,
Due to a sudden change in design requirements with regards my circuit supply voltage I'm looking to change my voltage regulation on my circuit from the classic LM7805 linear voltage regulator to a switching/buck regulator.
This is my first time attempting to use switching regulator so...
Hi all,
I'm being advised by my boardhouse a change in firmware might occur and I would like to cross check this on the forum.
Essentially the situation is in order to enable the running of my PIC18F2580 on +3.3V I need to switch to the PIC18LF2580 which operates between ranges of 2.0v TO 5.5V...
Hi all,
I’m looking to change my design in terms of powering my PIC18F2580 (IC3 on my schematic below) from my MCP1703 +3.3v voltage regulator (IC2 on my schematic below) - **broken link removed**.
See my schematic screenshot below:
Currently I’m supplying power to my PIC18F2580 from my +5V...
Hi all,
Apologies if this sound trivial but currently I’m stuck in terms of figuring out the logic to complete what I suspect is a fairly easy task.
I’m currently turning on my LEDs for a certain amount of time using the output_toggle() method as seen in my code below at the end of my post...
