still a error Brigde17 V0.3, I have to video , can see it

I use Led to the replace for motor

white and green LED on the left is forward
White and red LED on the right is reverse
Blue leds in the center, use pin 6 (flash )

error occurs at the beginning of the film 00 to 35
when the joystick in the forward position (adj trim )
turn tranmiter, LED white and green is turned on ( mode forward )

when the joystick in reverse position (adj trim )
turn tranmiter, LED red and white is turned on (mode brake )

if joystick the position forward or reverse , turn tramiter ,LED blue flashes (use pin 6 )
have to move the joystick in the neutral position., LED lights,and start working

V24 11 12 08 25 (1 min 9 sec)

It appears to be operating correctly.

If the 'error' is that if the throttle stick is not centered at start up, the motor runs as soon as a good signal is received, that is simply because the Throttle Arming feature was not activated (#define ARM).

if joystick the position forward or reverse , blue LED flashes (use pin 6 ), to move the joystick in the neutral position., and start working

On start up, you want to make the LED flash until the joystick is set to neutral?

Try this

thank you BRUCE
I checked the mode loss signal, the result is accurate LED display

I have completed the circuit, I would check and report the results tomorrow

I view program Brigde17 V.0.4, I have a question about brake mode
Is it similar to version 12f675?

Optional brake mode (1st time pulling stick down is brake, 2nd is reverse)

I understand it like this, if the move joystick down
 in a seconds, is the brake.
in two seconds is the reverse

Yes.

I checked the circuit, it works but it is not optimal because of the time delay

I do not know the time delay is by tranmiter and my reiceive, or by the processing speed of the PIC. motor response is slow

time processing pulse width, from minimum to maximum (or max to min ) of about 1s

braking force, it is increased by the PWM pulse width (min to max ). I want brakes are maximum , as soon as reverse

if there is any change, it will match the high-speed car

this is schematic layout by PDF,and file eagle

Response speed is determined by the #define STEP. I set it to 10 for ~0.5s from neutral to full throttle, but you can make it larger for quicker response (eg. 50=~0.1s, 127=~0.04s). Alternatively you could disable the #define SLOW (put a ";" at the start of that line) which will enable averaging mode with a response time of ~0.04s.

braking force, it is increased by the PWM pulse width (min to max ). I want brakes are maximum , as soon as reverse

Proportional brake is generally preferred because it allows the driver to vary the amount of braking force. To get maximum brake no matter what the stick position, add the lines in bold below:-

;--------------------------------------------------------------
;                      continue braking
;
brake_update:	movlw	255             ; maximum brake
		movwf	PwmWidth
		call	UpdatePWM	; set PWM width

Your PCB layout looks good.

version 12F617, tone * beep * from the motor was missing.

insert the one tone * Do Re Mi * or 3 tone * beep beep beep * (Frequency on 50hz to 500hz ) when determining the neutral position.

like the type esc that I have met

 add ASM code of the command? position? If program changes are not too difficult, please help me

thank so much

I have to modify according to your instructions, great results

I kept proportional braking mode, because I improve processing speed of around 50 (0.1 s). it reacts very fast

I started to design the circuit layout 2 layer, it will be much more compact. Post up as soon as completed

thank you for the new version

file eagle 2 layer

I started building the circuit, volt and ampe larger. ( verision 12f675 )
I use ir 2101. I think it will be effective

hello fantasy1988

i think with versions, 12f675, use ir 2101 driver bridge H is a mistake

fet above only works for a short time, then turn off

reasons: 2.7khz frequency is too high

you should use version 12f617, low frequency

I think this frequency is not high.I use 1uF capacitor, it can meet this frequency

test result ?
