小 TNC 是做好了,可没有找到 AX.25 信号 [复制链接]

我的样片已经收到了，已经用公司的hi-lo all-11编程器写好，回家就可以测试了，哈哈

仔细读了源程序，应该只支持9600波特，而不支持4800波特。正在跟作者进一步确认，如果这样，nmea0183的gps肯定是不支持的。已经知道怎么修改波特率了，希望这个修改能起作用。

类似于tt的模式还是不行，表现在发射led没有周期闪烁。设置我已经能在4800和9600两种速率下通过超级终端做了。正常的模式下beacon也能周期的发了，别的还没有试，跟大家的情况都差不多。

　　我的测试结果也基本是这样，也没有什么进展．
　　
　　
　　
　　
　　

这个机器的主要功能是digipeater，可以通过如下方式设置测试环境：

tt作为发射，88 tnc作为digi，再找个agwpe作为接收，用uiview等软件查看。如果没有无线条件，甚至可以用有线进行测试。

8te，你是用88 tnc解的吗？

上面我是用agwe和kiss都可以正确解码，
下面是用16f88解码就不行，出来是乱码

看起来这个16f88 tnc的解码能力比较差，我也获得了类似的结果。另外，接gps发送位置数据的类似tt的功能也不正常。不过，我的实验结果表明，这个tnc的digi功能是正常的。实验配置：tt的输出通过有线接16f88 tnc的音频输入，16f88 tnc设置digi on，然后将音频输出接agwpe。

我的结论是：有一定的实验价值，digi部分的源代码可借鉴。

我的今天在6cr的指导下16f88的digi已经可以正常的工作了。
连接如下
tt的输出通过tk208发射，5r接收到的音频接16f88 tnc的音频输入，tnc的输出连接到pc的mic端，启动软件agw和ui32

询问了作者关于无法支持4800波特gps的问题，得到回答如下：

1、本来的程序的确只为9600波特设计，如果使用4800波特gps是不行的。可以修改波特率。

2、如果修改波特率还是不行，请运行附件中的测试程序（请将扩展名从txt改为hex，直接烧写），串口速率已经改为4800了。最有可能的问题是接口线不对，语句设置不对，语句的结束符不对。

使用测试程序，要专门做个调试用的串口线，用两根线从gps送数据到tnc，再用两根线从tnc送数据给pc的终端程序。具体的注意事项和说明如下：

=======================================================================
; having problems getting your gps receiver to interface???
; in tnc version 1.10, code is added to print out some diagnostics to help you figure out what is
; wrong.
; here are the steps:
; 1. build a temporary test cable that splits the serial input and output leads. connect the gps output to the
;"serial in" lead on the tnc (pin 4). run the "serial out" lead to your terminal serial input lead.
; also connect the ground lead (pin 5) to the terminal and gps. this test cable will let you get
;diagnostic messages from the tnc while still sending nmea sentences into the tnc from the gps unit.
; 2. set your unproto and mycall parameters as you normally would. also set your beacon interval
; short (i use 1 min). . set the gps option to match your particular gps receiver and aprs setup.make sure to "perm" these values
; 3. install the gps enable jumper and cycle power.
;
; you should see the following message:
;
; gps mode,waiting for beacon timer..
;
;if you don't see this check out the wiring for pin 4 on the chip, the serial wiring, or
; your terminal configuration.
;
; when the beacon timer expires (ie 1 min) you should get the following message:
;
;
; searching for gps output:
;
; the tnc is now looking for a valid nmea sentence. it should consist of first a '$' character
; followed by a the nmea type (ie gprmc) and a comma. after that is a long ascii string followed by a
; carriage return and lf.
;
; version 1.10 tnc software will send out a '$' when it sees the start of the sentence, a 'f' if the type
; doesn't match the type set in your configuration (ie gprmc), and a timeout message if it stops
; seeing chars from the gps.
;
; thus a normal sequence at each beacon interval will look like this:
;
;
; searching for gps output: $
; ok
;
; the ok indicating that the message was valid and was sent.
;
; if no characters are received from your gps in 5 seconds, this sequence is displayed.

; searching for gps output:
; timeout!
;
;
; some gps units will repeatidly send multiple sentence types (ie gprmc, gpgll). an 'f' will be output to
;indicate each sentence type that has failed. thus you could get a sequence as follows:
;
; searching for gps output: $f$f
; ok
; this indicates that 3 types of sentences were seen and the third matched what was set in the
; configuration setting.
;
; hopes this extra information helps you get the interface debugged with your gps.

关于解码乱码问题，作者说这个tnc只能解最长256字节的数据包（包括包头等在内），所以长数据肯定不行。

他和别人的测试结果表明，解码效果和mx614类似，目前我们的测试还没有达到这个效果，可能还需要调节一下电平或者考虑干扰的问题。

这个是bd6cr送的外壳装的16f88tnc。

本来感觉这个外壳还不够漂亮，但是跟mfj-259b比起来一点也不差。bd8te做得也很漂亮，很好！

好漂亮啊 严重羡慕中 啊啊
能问一下两位老师这个电路板和外壳还有吗?我想........嘿~~~
谢谢

外壳是bd6cr提供的，pcb是我自己做的。如果你有16f88

请问这个tnc的音频侧可以接电台的data口吗？还需要转换或隔离吗？
我买了健伍的d700，还想再搞个这样的tnc，把8800r连上，自己就可以测试了。
我申请的16f88样片12月19日已经从泰国仓库发出了，但现在还没收到。

bd1li方便吗？我这周在北京出差，如果方便去欣赏你的作品，顺便学习。
