求6通详细解说。

http://www.overkillrc.com/gt3bfeatures.htmFeatures for GT3B-PSX Firmware (0.4.1)

• 3-8 Channels
• Trim (CH 1-2)
• Sub trim (All Channels)
• EPA (All Channels)
• Dual Rates
• ABS Braking
• Model Memory (14)
• Expo
• Lap Counter
  

Advance Features

• Backlight time
• Inactivity Alarm
• Low Power Alarm
• Max EPA allowed (100-150%)
• ST and TH Dead zone
• Key Beep (ON/OFF)
• Long Press Delay (Long press lets a switch have more functions)
• Default Setting reset
• All Model Reset
• Calibration Menu
• Key Test Menu
• Channel Speed (all channels)
  

Mixing

The New firmware comes with Dual ESC mixing and 4WS Mixing features. The mixs are simply enabled via a menu. The mixs can be controlled in numerous ways, in which it is setup in the KEY mapping menu.


Dual ESC allows for dig, even mix, and bias/proportional mixing. There is also a special feature for Dual ESC steering, for boats, tanks, etc.


4WS does the same thing as Dual ESC, rear/front only, even mix, bias/protional mixing. However there is a CRAB function that can be applied which will reverse on of the channels to give crab mixing




Multi Postion

Multi Position is a spectacular feature. What Multi Position is, is it allows you to have up to 8 independent positions, and to be able to cycle through them in what ever way you want with a switch. Which is great for mechanical digs, trannies etc. So you no longer have to go lock, free wheel, 4wd. you can do lock, 4wd, free wheel, or any combo!

Key Mapping

Key mapping does all the magic, its abit confusing at first when programming, but quite easy once you get a grasp on whats going on.

Trims/3 position switches

On the GT3B there are two 3 position switches and 2 (2) button switches. All of which can be considered a 3 position switch, referred to TRIMS in the manual. These switches can control

• Trim
• Dual Rates
• Expo
• Channels
• Sub Trim
• Mixes
• Multi Position
• Steering Speed
• Channel Speed
  

Now each one of thes functions can be controlled in many ways, here are the options

• Momentary
  
  • Key Must be pressed to change value...left e. point, center, right e.point
    
• No Long Keys
  
  • Each key press will change its function...according to step rate and other options, if you press and hold the key nothing happens
    
• Auto Repeat
  
  • Each key press will change its function...according to step rate and other options, if the key is pressed and held it will continue to increase by its step rate.
    
• Function Reset
  
  • Each key press will change its function...according to step rate and other options, If key is pressed and held the function will return to center/default value
    
• Function End
  
  • Each key press will change its function...according to step rate and other options, If key is pressed and held the function will go to its endpoint corresponding to the key direction
    

There are many more options to fine tune the above options, such as opposite reset, reverse, previous value, etc.

Buttons

There are afew buttons on the GT3B, But only one i'd suggest for use is the channel 3 button...Also all of the Trims can be separated into two separate buttons if needed. The functions Buttons can control are as follows

• Channels (e point to e point)
• Channel Reset
• Crab on/off
• Dig Mix (rear to front dig, but can be set to do even mix and dig)
• Multi Position
• Multi Position reset
• Increase lap count
• Lap count reset
  

这个周末我就把程序更新了试试看。最近实在是木有时间。

=====================20120525更新：进展更新。
刚刚去联系了机械加工商，请教了一个老师傅。坏消息是：之前的锁死差速齿轮的方案基本要被否掉，因为机械加工很难做到那么高的精度，还有强度，或者是成本太高，无法负担。
好消息是：可以在钢制轴承上打孔，这样可以选用锁死传动轴和差速壳的方案。这个比较容易实现，只是之前打孔的认为难度很大。另外差速壳内部需要重新设计，以简化加工，节约成本。简单的说，就是之前差速壳是模具注塑，是方形的，换成金属的很难洗出来，需要电弧腐蚀，慢而且成本高。现在设计成圆形的就可以了。

=====================20120527更新：进展更新。
我把GT3B的程序更新了，目前是8个通道。目前我用的接收是6个通道。功能比较复杂，还没弄清楚肿么用。firmware和烧写器就是我之前帖子中提到的那些。统统都是OK的。

明天中午去联系机件加工的师傅，做3个零件，本周末之前零件应该可以到位。

2台全新的1256TG已经在途中。

还是找不到断传，无限悲哀中。。。。。

实在不行在国外买吧，才30美金，加上运费，估计和国内的价钱一样。

回复 hzh007 的帖子

哥们
可否发个GT3B增加通道的详细教程
菜鸟很需要你的帮助
谢谢哥们了

马上讨论加工的事。

基本已谈清楚，明天加工处找人出图，我过去确认后，交订金就可以开工了。工艺比较复杂，需要电火花，线切割等手段，价格在400左右。
