The really small ones don't even have printing on them. Sizes like 0201
and 0402. Hand soldering these is something that should be used as the
basis for a silly TV program. 'Resistor wars', or som ... |

BTW does 2431 mean red-yellow-orange-brown ??
What ARE you on about???
I believe the 5-band color coding for this 1% resistor would be red-yellow-orange-brown-brown. Using 5-band 1% thr ... |

I hope you did not lose too much sleep over it
Being close to extinction myself I like a challenge so I heated up the welding torch and got to it. I'm not too miffed about the result:

Now I'm assuming that you are using the internal I2C pull-ups?. If so, FME has the extra function, of changing the current this peripheral
produces. Hence why the bus works when the FME bit gets set, ... |

Man, this is complicated.
I renewed my compiler. This seems to partly solve my problem. I now can use the FAST=nnnnnn parameter in #use i2c() and that gives me the desired baud rate.
But I fin ... |

Hi,
I don't want to start a new thread as this one exactly describes the problem I run into.
My question: did anyone ever find out why #use I2C() does not work for setting the I2C clock speed?

I managed to forget to put two pull-ups on a prototype I'm working on. No immediate need to heat up the soldering iron, because for birdbrains like me the 18F14Q43 contains I2C pull-up circuitry. Good ... |

Yes, quite some time ago. I looked it up; according to the time stamp the code was lastly compiled with CCS PCW C Compiler, Version 3.110 on 10/18/2002
It interfaced a PIC16f628 to an MT8870 ... |

Will do. They'll probably ask me to renew my license first as that timed out last October, but that will be worth it |

I have a LoRa device that needs a unique 32 byte Appkey programmed in every unit. I managed to make this work with #serialize, the ICD-U80 and a file containing the keys. Kudos to CCS for having thoug ... |

I use Timer0 as the go-to timer in nearly all of my programs. Its interrupt is used to maintain timers to blink leds, generate seconds or minutes, pulse relays, debounce switches and what not. Normall ... |

Yep. 950 pages of datasheet and the idea that you can fix things afterwards makes you cross-eyed and lazy and that leads to surprises. OTOH, I was saved a couple of times by CLC functionality, so I am ... |

In the LoRa prototype I'm working I want to use as little power as possible, so I sleep the MCU most of the time, only to wake it up on a power event or an external timer event. These interrupts I att ... |

WOW!
I have not looked in detail at the code yet, but it takes the 'ROM used' down from 5984 to 5660 bytes. A lot more efficient.
As always, thanks for the explanation. I learn from it!
