altos: Switch PWM constants to end up exposing µsec

2016-01-10T23:56:21+00:00

This changes the constants so the clock runs at 1MHz, making the step 1µsec each. Then make the period 20000 steps, or 20ms for a 50Hz frequency as before. Signed-off-by: Keith Packard

altos: Set TeleMega v2.0 PWM to support servos

2016-01-10T23:45:21+00:00

Typical servos use a 50Hz signal with less than 10% duty cycle. Set the divider to 10 and the range to 64000 to provide a reasonable level of detail down in the low range. Signed-off-by: Keith Packard

altos: Insert inter telemetry-packet delay

2016-01-10T17:09:09+00:00

The receivers take some time to reset the radio between packets, so make sure we don't send back-to-back telemetry too quickly by delaying after sending each telemetry packet.

Switch TeleMega v2.0 to CC1200 radio chip

2016-01-10T00:29:20+00:00

That's what we're using, after all Signed-off-by: Keith Packard

altos: Set AO_PWM_TIMER_SCALE for telemega-v2.0

2015-12-26T07:30:16+00:00

This is needed to configure the PWM timer correctly Signed-off-by: Keith Packard

altos: Get stm32l pwm driver working

2015-12-26T07:20:29+00:00

Fix the CCMR1_OC1PE and CCMR2_OC3PE values. Disable clock when no PWM outputs are running. Fix the apb1enr value for the timer. Set ARR value to PWM_MAX - 1 -- ARR is off by one. Sets the GPIO pins to 40MHz bandwidth for sharper edges. Tested on EasyMega, but that code is not included as it breaks the companion protocol. Signed-off-by: Keith Packard

altos: Add TeleMega v2.0, including PWM driver

telelco: Fix pad reset to one on radio signal loss

2015-10-13T20:54:28+00:00

The pad number was getting reset back to one when signal was lost, causing pad one to get fired in this case even when already set to arm mode. Signed-off-by: Keith Packard

altos/telelco: Adjust drag race UI

2015-10-13T20:54:28+00:00

Enter/leave drag race is done by rotating the box selector knob to a new 'dr' position and then holding down the firing button; this avoids a potential accidental firing if you somehow don't realize you've armed the box before selecting drag race mode. Signed-off-by: Keith Packard

altos/telelco: Add drag race UI

2015-08-30T00:32:54+00:00

With the unit disarmed, press and hold the fire button for five seconds to enable drag race mode. The display will show 'dr' for five seconds and beep five times to indicate that drag race mode is enabled. The decimal points in the display will all be displayed as an additional visual aid. Once every five seconds, it will beep. With drag race mode enabled, you can select a box/pad pair and press the 'fire' button to add it to the drag race group. For the current box, all members of the drag race group will have their continuity LEDs blink slowly. There will be no indication of continuity in this mode; you'll want to check that before enabling drag race mode. If you want to de-select a member of the group, just press the fire button again. Each time you push the fire button, it will beep out the pad number added or removed. Arm the box and you will not be able to add or remove members from the drag race group. Firing will simultaneously fire all members of the drag race group. To disable drag race mode, press and hold the fire button for two seconds. It will beep twice and turn off the decimal points in the display. Signed-off-by: Keith Packard
