Unsigned char data_rcvd = Serial.read() // read one byte from serial buffer and save to data_rcvdĪs you see I am sending a byte and receiving it again, what makes me think that the data is sent wright is because the led is working as expected, but when I print the data on Arduino serial monitor, it is printed as follows.
#RTWLAN DRIVER CODE#
put your main code here, to run repeatedly: Serial.begin(9600, SERIAL_8N1) // initialize UART with baud rate of 9600 bps put your setup code here, to run once: I am sending data through UART between PIC Micro Controller and Arduino. The role of this function is not send requested file (index.html is automatically send by step 3,4 and 5 in this case).This function is implemented for analyze valiables and control output by the following the valiables. Sixth, TCPIP_HTTP_GetExecute function is automatically called when received GET request. Thirdly, File that linked to http requested file (index.html in this case) is automatically searched.įourth, The searched directly for these files is mounted by SYS_FS_Mount() function written in app.c.įifth, Response message consisted of http header and html body is automatically generated and send,and if the dynamic variables (inside a pair of tilde (~) ) are exists in html file, TCPIP_HTTP_Print fuunctions are automatically called and executed to replace the valiables. Secondly, The request is reached the web server and the url parameters are stored in the connection data buffer. Figure shows the process that I guess.įirstly, Web browser send GET request with url including valiables (url parameters). Then i guess how GET process works in http server. The sample code doesn't contain file sending units. The problem is that i can't understand the process from receive request to send response. I've tried to make http server with FatFS file system referring to web_server_sdcard_fatfs( ). } while((rows & rows & rows) != 0x0F) // wait for keys release if ( (rows & rows & rows) = 0x0F) // will be 0x0F if all three values are 0x0F If ( (rows & 0b1000) = 0) // will be zero if the "0" button is currently pressed. If ( (rows & 0b0100) = 0) // will be zero if the "0" button is currently pressed. If ( (rows & 0b0010) = 0) // will be zero if the "0" button is currently pressed. If ( (rows & 0b0001) = 0) // will be zero if the "0" button is currently pressed. Rows = PORTB & 0x0f //read all four rows1 buttons #define C3_DIR TRISBbits.TRISB6 //Column 3 is set portB6 as output #define C2_DIR TRISBbits.TRISB5 //Column 2 is set portB5 as output #define C1_DIR TRISBbits.TRISB4 //Column 1 is set portB4 as output
#define C3_DAT LATBbits.LATB6 //Column 3 is set portB6 as output #define C2_DAT LATBbits.LATB5 //Column 2 is set portB5 as output My code is: #define C1_DAT LATBbits.LATB4 //Column 1 is set portB4 as output Microcontroller: PIC18F4550 MPLAB X IDE, XC8 with PICkit3.
#RTWLAN DRIVER HOW TO#
So far I am able to write the code to print on LCD but I am not able to figure out how to ask MCU to wait for a keystroke and then print.Ĭan anyone suggest me what is the logic to do it? I am writing a code where the user can press a key corresponding to the information the user wants to know and print it on the LCD Display.
