Hello Ttelmah,
What you describe is very, very close to what I proposed. I was not intending to use an external RC oscillator. I was intending to use the internal 32kHz oscillator and the external ... |

Hello,
Thanks for the reply. The 24MHz does need to be accurate, I'm afraid - It's used to derive the timings for a TI DSP based acquisition system.

Hello,
I have a power sensitive application using an 18LF8722 running at 3.3V/24MHz. The oscillator is an Epson SG350 module (http://www.eea.epson.com/go/Prod_Admin/Categories/EEA/QD/Crystal_Oscill ... |

PCM programmer,
In that case I am a donkey, and you are a god.
Many, many thanks for that. My design is safe!
Cheers.

Hello,
I need some clarification of Fmax on an 18LF8722 (and 18LF4620). The datasheet for the 8722 (39646b.pdf) in figure 28-3 on page 379 shows a graph with Fmax attainable at 4.2V, and stating th ... |

Thanks for the comments. The program I posted was merely to show the issue in the simplest way possible - It's not the program I'm writing. I actually need to call send_id with a variable, not a const ... |

Hello,
I'm an infrequent C programmer, and I realise that the use of string constants in CCS C is a no go. During the process of learning this I experienced some mighty strange behaviour. I've cond ... |

Hello again,
The answer is now obvious! I just need to disable the uart!
bit_clear ( RCSTA, SPEN ); // Disable serial port
Then I found this in the compiler readme.txt dated 4th July 200 ... |

Hello,
Thank you very much for the reply - I'm off for the weekend now, and won't get a chance to get back onto this until Monday, but I'll check out the information over the weekend.

Hello,
I've searched the forum, but not found an answer to this one. My application is based on an 16F873 (although developing on a PICDEM2 Plus) and has two RS232 ports. One port is the main port ... |
