Built 13+ Tiny 13 v1.1 autopilot boards in-house.  Distributed boards into the group to break-even.


Currently building Tiny 1.1 boards in-house for a few group members, including myself.

A: the two relevent commands are below.  Replace [AIRCRAFT] with the name of your aircraft.


# cd ''[parazzi3 folder]'''
[[Category:Members]]
# make AIRCRAFT=[AIRCRAFT] ap.compile
 
to download code that has already been compiled
 
# cd ''[parazzi3 folder]'''
# make AIRCRAFT=[AIRCRAFT] ap.upload
 
'''Q:''' How do I get GCS to talk to the AP with straight serial and not a modem?
 
'''A:''' Here is an example of a section of my paparazzi3/conf/control_panel.xml
 
<session name="4 Matt Flight">
  <program name="link">
    <arg flag="-d" constant="/dev/ttyUSB0"/>
    <arg flag="-transport" constant="pprz"/>
    <arg flag="-uplink" constant=""/>
  </program>
  <program name="server"/>
  <program name="gcs"/>
</session>
 
'''Q:''' How do I load the USB Bootloader onto the Tiny?
 
'''A:''' Start by wiring up 3.3V RS232 from the PC to the Tiny. 
 
The serial lines on the ARM7 micro are 5V tolerant so if it helps cut down on complexity/parts you could use 5V RS232 for this.  ''Optional: You could also form a basic resistor voltage divider on the PC TX -> AP RX''
 
*PC SERIAL_TX -> LPC_RXD_0 (SERIAL_1-7)
*PC SERIAL_RX -> LPC_TXD_0 (SERIAL_1-8)
*PC SERIAL_GND -> GND (SERIAL_1-1)
*LPC_P0.14 (SERIAL_1-5) must be asserted low (held to ground) while the Tiny powers up in order to enter the Serial Boot Loader.  (You could also wire this to a pushbutton which ties it to ground, holding this button briefly while you power up the AP.  This pin does not need to stay low during the programming or any time afterwards)
 
once these connections have been made, execute this command in a console
