"I am 100% certain you can not run 12v strip with the outputs of the atmega 2560 at a hardware level (fry the chip). 5v will be the output but even still the milliamp rating on the 2560 is not high. You should use a switching transistor to drive the…"

I need some expert APM2 Telemetry help.I'm using the Xbee XSC 900mhz units. Which sadly have a maximum RF baud rate of 9600.I'v managed to configure the SERIAL3_BAUD to "9" for 9600 (also tried "4" /…Continue

Hi everyone.I'm planning on a quad build with the APM2. I'v done some arduino projects but still quite green in the arduino field.I'd like to design a very capable lighting system for the quad as I…Continue
Trying to get my thoughts in order.

OK everyone, I'm really going to need all your expert advice.I'v decided to start on a quadcopter project.I love what DIYDRONES has brought to the table. I'm a linux user and believe in the open…Continue

giancarlo.forum replied to TJ's discussion APM2 Telemetry rate"Sorry everybody, i just need time to find it.@Dwgsparky i didn't say xbee only works at 9600, i just testing at that baud.
I could change baud, i don't sure where is it because i found 2 place.
First in config.h lines 295-300 as…"
Dwgsparky replied to TJ's discussion APM2 Telemetry rate"Hi
Looking at your question you say the xbees only work at 9600, I think that is incorrect!
when the xbee is shipped it is set at 9600 but then you use the CTU program from digi to change this as you wish , my Mission planner connects to the same…"
giancarlo.forum replied to TJ's discussion APM2 Telemetry rate"Hi all,i tested "MultiSerialMega" with Serial and Serial3 in 9600 baud, i received "Port 0" in both case, from USB and then from wireless when power by battery. So, i want to set Telemetry in Serial port.
I have to do 2 change.…"
Jim Kahl replied to TJ's discussion APM2 Telemetry rate"Sounds like we're both on the same path and have drawn the same conclusions. Like you, I also mistakenly took some of the Arduplane comments as belonging to Arducopter.
If Andreas is still monitoring this thread, maybe he can let us know…"
TJ replied to TJ's discussion APM2 Telemetry rate"I am now using arducopter 2.7.1 on APM2 and still don't have telemetry working
I too have seen the Serial3_BAUD parameter in the list as well as standard parameters in the mission planner. Serial3 just does not seem to physically exist on the…"
TJ replied to Masafumi Miwa's discussion How to set up serial3 on APM2?"Can you give more details Masafumi? I have tried off and on for a long time to get telemetry working. Like the OP, I have tried the multi serial mega sketch and found I can get data out of UART2 header on APM2 using "Serial2". Serial3 is…"
Jim Kahl replied to TJ's discussion APM2 Telemetry rate"Andreas,
I think that you hit it! I checked through all of the blog entries and the wiki, and it appears that arduplane and not arducopter has the UART2 telemetry feature enabled.
"
Jim Kahl replied to TJ's discussion APM2 Telemetry rate"I'm not sure which device TJ is using, but I'm working with Arducopter. I noticed that the planner (v1.1.96) just added a setting for Baud rate on Serial port 3. It's always been in the parameters menu, and could have been changed…"

"
I am also interested in using UART2 on APM2 for a modem
I will be looking into this also, so please post any updates (I will too).
Can you specify explicitly: Have you tested this on ArduCopter, or ArduPlane?
"
DeveloperAndreas M. Antonopoulos replied to TJ's discussion APM2 Telemetry rate
"TJ,
Is it possible that you are testing Arducopter and looking at notes for arduplane?
Above you said "More research shows that in arducopter 2.34 support for UART2 was added based on the following post by a member of the development…"
Jim Kahl replied to TJ's discussion APM2 Telemetry rate"I'm in exactly the same place. I can't seem to find a way to enable UART2 for telemetry. I've also cut the micro traces and put the solder jumpers in place. This puts UART2 out on both the UART0/2 connector and the UART2 connector on…"
TJ replied to Graham Miller's discussion APM2 GPS"Graham, as you stated, blue light on the GPS indicated a fix, the red light should blink continuously unless you have armed the motors. the blue light next to the red light may be solid or flash depending on activity of the board.
You should be able…"
TJ replied to TJ's discussion APM2 Telemetry rate"Two days, no telephone tech support, no reply to email. Called during their stated business hours, but telephone system says they are closed. Not much community input either :( All I would really like to know is if any of you have…"
TJ replied to TJ's discussion APM2 Telemetry rate"More desperate testing. It would appear that UART2 on the APM2 is not connected to Serial3 as all the documentation I have found says. I uploaded a simple arduino program that prints the text "Port X" to SerialX.println and well, it would…"
