I got a brand new APM1 recently. I soldered it quickly. But when I tried to upload the firmware the mission planner could not detect the APM version. I have not debugged it completely bit seems…Continue

I got the 3D Robotics optical flow device few weeks back. Yesterday I soldered the connecters and loaded the sketch " AP_OpticalFlow_test.pde" to an Arduino mini pro. I selected digital pin 10 to…Continue

Block box for APM, FLASH memory verses EEPROM
Started Jun 14, 2012 0 Replies 0 Likes
In APM1/APM2 I see that a flash memory chip is used for black box functionality. I see that EEPROM memory is also available in same package and same interface(i.e. SPI. etc.). In that case I was…Continue

Cool Dude commented on Joshua Ott's blog post Thirty days (#6): You can't make an omelette without breaking a few eggsCool Dude posted a discussionHow to use 3D radio with PX4 board.
PX4 used 3.3 Volt ARM chip. The 3DR radio used 5V signals. In that case I was wondering if 3DR telemetry radio will work OK with PX4 board. I realize that we have to supply 5V power to the radio, but I was wondering if the 3Volt TX signal from PX4 will be able to drive the radio, similarly the 5Volt TX signal from radio will not fry the PX4 board. Sorry if the question is silly but my knowledge of h/w is very limited.PS: Can we have a separate forum for PX4 issues?See More
Cool Dude replied to Andrew Tridgell's discussion ArduPlane 2.69 released"Can you please tell us how can we build the Arduplane for PX4. The Arduino 1.0.3 does seems to support only APM1 and APM2.
Thanks"

Jesus Pestana replied to Cool Dude's discussion Optical flow not working using the test sketch ( SOLVED)"Hi Cool Dude and the others,
I am a newbie with arduino. I am trying to setup the Optical Flow sensor on an Arduino Board. I believe this is really similar to your configuration, since the "Arduino mini pro" is…"

"@Peter,
You have to use both ISP ports. One for the 2560 bootloader and one for the 328 bootloader. Then you have to load the 328 with PPM/Mux firmware.
Just a thought.

TCIII"
Cool Dude replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"Hello Peter,
I had the same issue. No boot loader in Mega2560 and no PPM firmware in the PPM chip. I had to flash both and now it works fine. I have AVR Dragon, which I used to flash the bootloader and the PPM firmware."
Peter replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"Hello,
I think there is more to the missing bootloader than you might think. I am in the same situation here. But when I finish putting bootloader and upload APM firmware. I notice that the LEDs in the bottom board are…"
Tony vh replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"After much research, I managed to load the bootloader unto the APM2560 using my $4.95 usbasp device connected to the SPI connector on the APM2560. I used avrdude 5.11 in the windows terminal to set the fuses and load stk500boot_v2_mega 2560.hex to…"

"Cool Dude,
Check the link that I provided for burning the bootloader with the Arduino IDE. I believe that it points you to the location in the IDE file structure that has the various Atmel bootloaders.
Regards,
TCIII"
Cool Dude replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"Hello Raphael Diaz,
Can you please point me where you got the hex file for the atmega2560 bootloader. I will use it to burn the bootloader in my APM1.
Thanks

Raphael Diaz replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"problem solved. i had to burn the bootloader for the atmega2560. i can now connect to the mission planner!!!"
Raphael Diaz replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"i mean AVR programmer not ISP"
AdminThomas J Coyle III replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?
"Raphael,
Can you connect using an FTDI cable to just the APM1?
Regards,
TCIII"
Raphael Diaz replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"well i was able to load the arduplane firmware using my arduino uno as the ISP programmer. i cannot connect through the mission planner still"
Raphael Diaz replied to Cool Dude's discussion No boot loader installed in the Mega2560 ?"correct however you still need an AVR programmer which is what the arduino uno is acting like."
