Re: Yet another PIC14
Thank you, Phil. An EasyEDA file. Perfect!
Have you had an opportunity to take advantage of the JLCPCB/EasyEDA promotion (see below)? |

Re: Yet another PIC14
Hi Mike, yes I got them at the reduced rate, but I wasn't aware it was ongoing, that's good!
Meanwhile I added an overlay... it is looks much better than the pic, light reflection from the camera |

Re: Yet another PIC14
Oh, yes, that does look nice.
Happy to hear that PCB promotion is good in the UK, too. vy 73, Mike |

Re: Yet another PIC14
I tried the PIC16F876A's kindly donated by Sirius and as expected they work fine in the PIC14, also I found another PCB so for anyone wanting to join in the fun we will have three PIC14 PCBs each with a programmed 876A chip up for grabs FoC
All you need is a ULN2003, some buttons, two-off four-digit 7-seg common cathodes, a 20mhz crystal, and a CH40G module for uploading (mine & Wiggles are powered from the CH40G, no 7805). And a few decoupling caps Cheers Phil |

Re: Yet another PIC14
No probs RT, sorry too late to edit previous post, the serial USB module is a CH340G (the "3" key is bad on my workshop laptop!)
