Thanks for ur help! Ill post on here again once i get some real data."
Ryan Johnston replied to Ryan Johnston's discussion Log file often not generated"Yep tried that 10 minutes ago, and iv just produced a valid log . Im hoping thats fixed it! Maybe it rewrite over the old log. Weird.
Im testing it again now. It was successfully creating a small log occasionally before so it could…"

"try doing a log > erase from the cli. and then the log"
Ryan Johnston replied to Ryan Johnston's discussion Log file often not generated"Iv just tried logging for another 10 minutes. Still no log file being created, the same result as most of my flights. Since its connected to APM Planner through USB, i tried logging data through my PC. That worked fine, it created a tlog which i…"
Ryan Johnston replied to Ryan Johnston's discussion Log file often not generated"Hmm thats interesting. I figured that since the log was under 1mb it wasnt a space issue. It could indeed be that im running out of "pages"
Iv tried turning off everything except for the essentials: ATTITUDE_MED, GPS, MODE,…"

Jnixetra replied to Ryan Johnston's discussion how to connect logic to hardware with the APM board"which line should i look at so it state the pin number? i'm not sure which one is the digital output pin or analog output pin of the APM board... :("

"the log you posted uses the entire dataflash
Dumping Log number 1, start page 2, end page 4096
4096 is the last page in the dataflash, so it would appear your using the entire dataflash for these short logs.
ie…"

Hi, After each flight i try to download the log file from my APM unit. Sometime it generates a log file, but most of the time it reports that there are no logs to download. Im taking off and landing manually & flying around waypoints autonomously. When i do get a log, its only a small part of the flight. Iv turned on all log-able fields in the terminal. Im trying to understand when the log files are wiped. I assume that its when the APM unit loses power? APM gets reset each time i switch…See More

"The Arduino tutorials can help you with PWM output. (It's really easy). Note that we don't use most of the native Arduino methods you'll see there in APM, because they're not efficient enough at the scale we're working…"
Ryan Johnston replied to Ryan Johnston's discussion how to connect logic to hardware with the APM board"Woohoo, iv finally got outputs & LEDs going.
I understand the schematic now. I assumed that the outputs were coming straight out of the ATMega1280 unit, I was getting very confused.
Iv never been so happy to see flashing lights in…"
