I want to send data from my GPRS module (Huawei GTM900 -http://www.lankatronics.com/huawei-g900-gprs-development-module-with-antenna.html ) to a server on web. I plan to use a micro-controller pic 16f877A for this connecting GPRS module via UART port.
First i tried to check my module with my...
working perfect. Thanks
Any idea on how to limit dcimal places on float?
for an example i prefer 2.333 instead of 2.33341.
(i tried sprintf but it is not available for pic 16f877a)
there is nothing on the receiving side then. (also there are two $ marks on transmitting side too)
Can you give me the full code please? I am new for programming and greatly appriciate your help.
Thanks
I tried but no luck.
at transmit side i put,
char *res; // at the beginning
res = strcat(buf, "\r\n");
ltrim(buf);
UART1_write_text(res);
Lcd_Out(2,1,res);
>>>>>>>>>>> nothing on lcd
at receiving side i put,
char *output; // at the beginning
UART1_Read_Text(output,"/r/n", 255); //...
i used "inttostr" command to convert number into an text. How to put "\r\n" at the end of this?
Can you show me the code, how to do this?
I also appriciate if you can give me the receiving side command too.
Thanks
Hello all,
I am doing a simulation of sending analog voltage from one place to another place via RF modules. This voltage is an output from a sensor. I am using 2 pic16f877a micro-controllers and RF transmitter and a receiver.
My transmitting side works perfectly fine. It reads the analog...
