 ### Connecting a Spektrum-compatible satellite to a Flip32+ flight controller

-The Flip32/Flip32+ is wired in a rather strange way, i.e. the dedicated connector for the satellite module uses the same UART pins as the USB adapter. This means that you can't use that connector as it maps to UART1 which you really shouldn't assign to SERIAL_RX as that will break USB functionality. (Looks this problem is fixed in later versions of the Flip32/Flip32+)

 In order to connect the satellite to a Flip32+, you have to wire the serial data pin to RC_CH4. This is the fourth pin from the top in the left column of the 3x6 header on the right side of the board. GND and +3.3V may either be obtained from the dedicated SAT connector or from any ground pin and pin 1 of the BOOT connector which also provides 3.3V.

Author	SHA1	Message	Date
Michael Hope	52c28161f8	Revert "build: enable -ffast-math." This reverts commit `2082ecbb06`.	2015-05-23 05:08:21 +02:00
Michael Hope	2082ecbb06	build: enable -ffast-math. By default, GCC implements strict IEEE 754 confirmance and chooses bitwise accuracy over speed. -ffast-math relaxes this and lets GCC do optimisations like re-writing a / constant as a * (1 / constant). Saves 144 bytes of flash and should be a speedup. Signed-off-by: Michael Hope <mlhx@google.com>	2015-05-22 04:50:18 +02:00
Michael Hope	c5a5844297	serial_cli: use the reentrant version of strtok(). Newlib's strtok() allocates memory and causes malloc() to be linked in. Use the reentrant version instead. Saves 336 bytes. Signed-off-by: Michael Hope <mlhx@google.com>	2015-05-22 04:50:11 +02:00
Michael Hope	d8f2ce9f79	various: use float instead of double. Add 'f' suffixes to some constants so they don't get silently promoted to double. Use roundf() instead of round(). Saves 208 bytes of flash. Signed-off-by: Michael Hope <mlhx@google.com>	2015-05-22 04:50:05 +02:00
