moxaUC8410学习笔记

MOXA UC8410 学习笔记1. 交叉调试环境构建构建UC8410 交叉调试环境中碰到很多波折,以此文为记录。
整体步骤:1. 在windows 上安装Ubuntu 虚拟机。
2. 安装vmware tools 。
3. Ubuntu 下访问windows 共享目录。
4. Ubuntu 可通过无线网络上网,一些必要的程序需要安装。
5. 在Ubuntu 上安装nfs 服务器,并验证,然后可在uc8410 上挂接Ubuntu 下的目录。
6. 在Ubuntu 上安装工具链,并编译程序,然后下载到uc8410 执行。
7. 在uc8410 上安装gdbserver。
8. 交叉调试。
IP 地址约定:Windows 主机:有线ip 地址:192.168.3.5,无线ip 地址:192.168.0.102(DNS 方式获取)Ubuntu 主机:有线ip 地址:192.168.3.8,无线ip 地址:192.168.0.103(DNS 方式获取)Uc8410 网口1ip 地址:192.168.3.1271.1 安装Ubuntu 虚拟机该步骤相对比较简单,网上提供了很多图解教程,默认安装后磁盘结构如下:其中dev/shm,var/run 都为内存目录,Var/run 目录中存放的是自系统启动以来描述系统信息的文件。
1.2 安装vmware tools安装完Ubuntu 后,需要安装vmware tools,可以方便在两个系统之间拷贝文件,共享目录等。
在Ubuntu 10.10 上安装vmware tools,我这里主要遇到的问题都出现在以下这步中,What is the location of the directory of C header files that match your running kernel? [/usr/src/linux/include]如果直接回车,会显示The path "/usr/src/linux/inc lude" is not an existing directory.因此,首先要更改该路径。

VPI debug: OFDM for Long-Haul Transmision************************2017/06/11AbstractSome tips and course in debugging VPI simulation of OFDM for long-haul transmission.ThisdocumentiswrittenforNadiyaAbd(nadiyaabd<***********************>)by H.B. Zhang (************************). Reprint without authorization is forbidden. Thanks for your cooperation.Change LogsContentsVPI DEBUG: OFDM FOR LONG-HAUL TRANSMISION (1)1 TIPS IN DEBUGGING VPI (5)1.1 TIP 1: SET RELATIVE PATH RATHER THAN ABSOLUTE PATH (5)1.2 LOGICAL LABEL ERROR (7)2 TIP 2: SIMULATION DEBUG (8)1.3 ANALYSIS THE RESULTS (9)1.4 CHECK THE SPECTRA (9)1.5 PN ALGORITHM (12)REFERENCES (13)缩略语清单1Tips in Debugging VPI1.1Tip 1: Set relative path rather than absolute pathThere is an error when I run this VPI project directly as I copyed this project to my hard driver.The ERROR info list as following:Because the module “ofdmdecodeergalaxy_vtmg2.CoSimInterface_vtms1” specified one path which maybe non-existing in my local path.Is there some way to avoid this error as running the project no matter where the project saved?There are 2 steps to resolve this problem:1. Move matlab file “ofdm_decoder.m” into folder “Inputs”:After you did this, you can find matlab file “ofdm_decoder.m” displayed in the “Inputs” of module “ofdmdecodergalaxy.vtmg” in the VPI GUI Window:2. Empty the “Path” in Parameter Editer of CoSimInterface_vtms1:Change other modules’ setting with the same method if you have many matlab cosimulation modules, in this project you should change module ofdmcodergalaxy_vtmg1.CoSimInterface_vtms1.After all the settings are changed, run the project again. The project could run MATLAB cosimulation properly. The results are depicted in the following figure.1.2Logical Label Error图1CDR logical channel errorThe CDR module, ClockRecoveryIdeal at the OOK receiver, can not work properly coz the CDR and BER_OOK_Stoch here needs NRZ/bits sequence with 1SPS, but original labeled “ch1” at the Tx. with a upsampling which larger than 1SPS. So, I change the position of the “channel label”, i.e., drop the “LogicAddChannel” in ofdmcodergalaxy module, and add a “Coder_NRZ” wich channel label “NRZ” followed “PRBS” module at the Transmitter. After these changes, the OOK and m-QAM ber module can work properly.Unfortunately, the simulation results are wrong. Maybe there are some other problem with the matlab code.图2The BER modules work properly2Tip 2: Simulation debugOriginal simulation results depicted in the following figure:图3original simulation results1.3Analysis the resultsThe large BER:1. low SNR: adjust the amplitude and bias of the MZM to enhance the SNR.We can get a quit good electrical spectrum with a high OSNR. Even with such high OSNR, the constellation and ber are not good. The problem maybe is the bug of the co-simulation MATLAB code. The code at the received maybe has a wrong de-modulation to the ofdm signal.1.4Check the spectraChecking the spectra and found that the downconverted spectra is wrong. It should be a baseband signal, but it is and passband signal now. So, check the LO source frequency, the miss matched frequency setting is 1E8, while the correct setting is 7.5GHz. Correcting the LO frequency, and the constellation shows a circle. The constellation shows much like the propertly constellation.To further clarity why we got a circle constellation, check the fiber length and CD settings, also correspongding check these settings in ofdm decoder. Everything shows OK.So, avoid the fiber channel, and check the constellation in EBTB. Same constellation.check the matlab code and the change the MATLAB code:compare the constellation before and after the change:Add fiber channel with CD=17e-6ps/nm. The constellation shows:Q u a d r a t u r eIn-PhaseScatter plot-505Qu a d r a t u r e In-Phase图4 Constellation with CD and CDE may not work properlyIt seems that the CDE does not work properly. Make some changes to the ofdm coder, then the constellation depicted in following figure:图5 Constellation with CD and CDE works properly-6-4-20246Q u a d r a t u r e In-Phase Scatter plot-6-4-20246-6-4-2246Q u a d r a t u r e In-Phase Scatter plot1.5PN algorithmFor QPSK signal, it’s phase are: 0, pi/2, pi, 3*pi/2. With 4x to the signal, its phase will be 0 in period 2*pi. So, with 4x algorithm we could estimate the phase noise and compensate the phase noise.with the PN algorithm, the constellation present as following figure:图6constellation with 4x PN algorithmThe whole simulation results now depicted in following figure, all the spectra and constellation are OK now.图7 Present simulation resultsReferences。

Guía de Ejercicios de Cálculo de Subredes
EJEMPLO 1.- Para la red 192.168.10.0 con mascara 255.255.255.0, obtener 8 subredes.
Solución:
1. Comprobar si se pueden tener esas subredes con la configuración dada. Si, si es posible tener las 8 subredes, porque hay suficientes bits a 0 en la máscara. Hay 8 bits a cero (y 8 2 es mayor que 8), como se puede observar en la mascará: 11111111.11111111.11111111.00000000 Los bits a 0 son los bits en verde. Esta mascara la ampliaremos para crear subredes, pero claro, la ampliaremos cambiando ceros por unos de forma que volvamos a obtener una máscara que sea correcta. 2. Calcular el número de bits mínimo para los subredes. Para tener las subredes que has especificado es necesario utilizar al menos 3 bits, porque 23=8 y este resultado es mayor o igual a 8 (que son el número de subredes que necesitas). Esos bits son los que deberás modificar para cambiar el número de subred. Ahora, fijate bien, a continuación se expone la máscara origen indicando en verde los bits que serán utilizados para especificar (en la dirección ip) el número de subred: 11111111.11111111.11111111.00000000 3. Calcular la máscara ampliada. Ahora, partiendo del calculo que se ha hecho en el paso de antes, calcular los bits reservados para indicar el número de subred, calculamos la mascara ampliada cambiando esos ceros reservados para subredes en unos, o lo que es lo mismo, los bits que se han marcado como verdes debemos convertirlos en unos. Tal y como se indica a continuación: 11111111.11111111.11111111.00000000 (255.255.255.0) Mascara orígen: Mascara ampliada: 11111111.11111111.11111111.11100000 (255.255.255.224) A partir de ahora, todas las subredes que tengamos usarán esta máscara ampliada (todas la misma). Los unos en color verde de la máscara ampliada son los que tendremos que cambiar en la dirección IP para indicar el número de subred.. 4. ¿Cuantos equipos habrá por subred? Los ceros de la máscara ampliada son los que utilizaremos para indicar el número de host dentro de cada subred. Como puedes observar en la máscara ampliada, tenemos5 bits reservados para indicar el número de host dentro de cada subred y esto nos permite tener 25-2 hosts por subred, o lo que es lo mismo, 30 hosts.

NOTA: Para obtener alguna subred en específico, se debe obtener el decimal asociado, respecto de los bits de subred (en este ejemplo, 3 bits de subred) Si quiere obtener la Subred 5……. Los bits en verde (101), es el numero 5

Área Electrónica y Telecomunicaciones Sede Arica Networking I 5. ¿Que tenemos que modificar en la dirección de red? Ahora, la mascara ampliada nos indica que bits podemos cambiar en la dirección de red . La dirección de red para la dirección ip que has indicado es: 192.168.10.0, con lo que según la máscara ampliada, los bits que modificariamos sería: Máscara ampliada: 11111111.11111111.11111111.11100000 - 255.255.255.224 Dirección de red: 11000000.10101000.00001010.00000000 - 192.168.10.0 Como puedes observar, los bits en rojo, son los que estaban de la mascara anterior, y esos no se podrán modificar, son intocables. Los bits en verde son los que modificaremos para indicar la subred, pero ojo, los cambiamos en la dirección de red, no en la mascara ampliada, y los bits en azul los cambiamos para indicar la dirección del equipo. 6. Listado de las subredes que habría A continuación, se muestran todas las subredes que se podrían crear con la configuración dada.
