Hi.
I want to use a bluetooth module hc05 with a custom (my) arduino that includes a micro ATMega32A.
first:
I used an arduino Uno (instead of micro ATMega32A) and everything is working perfectly.
Second:
but when I used ATMega32A and Arduino IDE to program it, unreadable characters are shown...
When I set the AT+CSCS="HEX" and then used from AT+CUSD=1,"*140*11#",15, received following answer:
How can I convert it to a readable message?
note :
I don't have any problem with send or receive sms via this module. only problem is this ussd to check the balance.
Yes,I'm sure. when I use this code (*140*11#) in the mobile phone,I will receive correct answer.
But I don't know that why answer by the module is incorrect.
I hope to see a solution or clue from someone:)
hi
how get sim card balance by gsm/gprs A6 module?
I used the following AT, but does not work and result in unreadable characters or numeric code.
note : my sim card language is English.
I used all four AT+CSCS that is supported by A6.but I can not get +CUSD: "English-message".
why?
AT...
hi.
I have a sony vaio laptop that does not boot.
my model: VGN-CS 190
i was using from visual studio 2010 and next installed an antivirus.
this antivirus found a trojan and I cleaned it.next my laptop was busy and I restarted it.but the laptop went to black screen (after vaio logo) and did not...
Re: error in c language : gets() after scanf()
thank you very much!
I'm agree with andre_teprom. gets() is not a very good function.
"Never use gets(). Because it is impossible to tell without knowing the data in advance how many characters gets() will read, and because gets() will continue to...
error in c language : gets() after scanf()
hi.
As you know,there is a problem in c programming language,when gets() comes after scanf().
in this case, first gets() after scanf() doesnt work.in fact the first gets() see Enter ("\r") and skip.
i used from an extra gets() to ignore this prblem...
I want to reverse a float number that is entered by user in the input.
float number = integer section . decimal section
for example if you entered 13.546 in the input, you have to receive 645.31 in the output.
my code work well for many float numbers,but in some cases (such as when decimal...
hi.
is there anyone who can write a full program that reverse a float number in C language?
I want to use from following commands:
1. if/for/while loops
2. I dont want use from any Function.please write a code with basic commands.
I wrote a code,but it's not true for some numbers.
for example ...
why when I use from one sided difference formula in boundaries (exactly same as my reference papers), my answers become divergent?
is there anyone who is familiar with higher order FDTD schemes?
hi.
Is there anyone who is familiar with higher order FDTD methods in dielectric interface modeling in one dimensional or more?
If there is,please reply.I have one question about dielectric interface modeling...
Yes,I know it.
I have a problem that interface is at (z=d) and I can not shift it to (z=0).
Now I want to write continuity condition of tangential E fields on interface z=d.
suppose we have:
Ex_incident = E0. exp[-jk1*z]
Ex_reflected = Er . exp[+jk1*z]
E_total_1 = Ex_incident + Ex_reflected...
hi.
I know reflection and transmission coefficients of plane wave normally incidence to dielectric interface when interface location is at origin (for example z=0).
now if interface location was z=d , this coefficients how changes?
is there anyone who give me a good reference or PDF?
THANKS
my code is true.you can easily reach to it by maxwell equations in one dimensional.
I obtained the result.
now i have one problem only.
how do I have to use from continuity condition of E fields at dielectric interface (in analytical answer).
I posted the code.please see your inbox.
I understand that what is the procedure.
exact solution is obtained by analytical expressions:
E(z,t) = E0*exp[w*t - k*z]
H(z,t) = H0*exp[w*t - k*z]
therefore, we have to compare FDTD result with analytical waveform.
NOW,my question:
can we use from E(z,t) = E0*exp[w*t - k*z] formula to plot...
