I have a problem communicating with the M95 via uart. When you send the uart command M95 mi returns the same command that I send. M95 turned on by the pwr key and status pin indicates to me that the M95 is turned on. via FTDI send from PC command "AT" and M95 returns "AT". The uart is used (...)
This is what I did, I use AT89S51 MCU with itead BT_Module, connect the BT_Module's RX to MCU's TXD and BT_Module's TX to MCU's RXD, also VCC(+5V) and GND of course. 105894105895105896105897 The baud rate of HC-05 in this itead BT_Module for both communi
Hi, I have problem sending command through using uart. I could not seems like able to communicate with my gps. my code is below. #define SYSCLK 99532800 // Output of PLL derived from (INTCLK*2) #define BAUDRATE_0 115200 // Baud rate of uart0 in bps #define BAUDRATE_1 9600//115200 // Baud rate of (...)
Hi, I am interfacing PC + DS89C450 + GPRS where I will send AT command from PC terminal (serial port 0) and DS89C450 will send the command to gprs modem (via serial port 1). Then the reply will go from gprs modem -> DS89C450-> PC terminal Now serial port0 works fine with the following configuration. /**********Serial port initializatio
you can use an uart interrupt. Use a getchar() function if you receive to your serial port the character e.g "A" and the second character is e.g. "T" then move each received character into an array as element.

I am using cc2500 with atmega32. I want to use cc2500 in uart mode because i think in spi mode it is too big to handle. for that purpose i did following things: 1. i reset cc2500 using sres command strobe.(0x30) 2. then i configured the data rate to 9600 by writing appropriate values of DRATE_E and DRATE_M in respective registers. 3. then i
I have this project using this PIC24F04KA201. I have two inputs coming from two sensors, temp and load cell. I want to acquire the two data via serial port(RS232) to be plotted using MATLAB.

Hi, First thing - are baudrate of you uart the same as baudrate of module? And second one - do you have an oscilloscope to check if sth is getting out of the buffer?
hi all please can any one help me i want to control a bluetooth chip (parani esd 1000) with micro pic18f4550 i have a problem in sending AT commandS VIA uart CAN ANY ONE SEND ME A SAMPLE FOR A C CODE (MICRO C) TO SENT ONE command & RECEIVE "OK" THE AT command EX: ATZ THANKS ALL :cry:
You have to do something like this, choose baudrate with is your default BT baudrate: char data = 'AT command'; void main(){ Soft_uart_Init(PORTB, 1, 2, 9600, 0); Soft_uart_Write(data); delay_ms(1000); Soft_uart_Write(data); while(1); }
hello to everyone I kown how to control servo motor and DC motor using h-bridge but I don't know how to combaine these two code together and can I control them usnig only one port such as B because I use uart and I can't control more than one port when I send the data through uart using PIC16f877A and MikroC Pro please help me thank you
Hi, Read library functions; Usart_Data_Ready Usart_Read in mikroC help. They are used to read return values via uart of a PIC. You should store return values in memory; then at the end print them on LCD. You can use LCD-library there also. similar discussions are on following threads; www.edab
Well warnings are pretty useful when it comes to efficient programming, it tells you about unused variables and other things which not necessary. but still with warnings your project can run you may ignore those when you are developing but by the end when you are finishing you should remove these warnings... now for your problem please tell which c
How to Send ATD and ATA commands from controller to GSM Modem through uart. Can anybody Plz send me the source code in C language
have you tried looking at the signals with an oscilloscope, e.g. write out to the uart "AT\n\r" in a loop 1. You should see the 3.3V from the uart then 5V into the modem 2. if that works you should the modem reply at 5V then 3.3 V into the uart this should show where it is failing (could the baudrate be incorrect?) a MAX3232 sounds a (...)
I want to use uart to send a code from pic16f690 to pic16f887. If the code is correct a led will be turned on. My problem is that none of my codes isn't work. Please help me. These are the codes: the emitter int i; void main(){ i=11111111; uart1_Init(9600); while(1) { Soft_uart_Write(i); }
hey all. i have a problem with a uart code i have made in MikroC. i have tryed many things, but cant make it work :I i want to send a text command via the uart and then the Chip lights up some certain leds, but i cant light 2 leds up at once and turn them off as i want to because the loop just keep following its path and i dont know (...)

hi recently i`m trying to send some data over another avr uart by fsk transmitter . when i connect two avr`s by wire it works great , but when i connect them to transmitter and receiver it has so many error`s and works too bad , have to send data 10 or 15 times to send data correctly. i think maybe it`s because of the uart that is high when its
hye..I am such problem which i dont know how to insert or apply command GSM module into verilog code.Because we know that uart transmitter and receiver will enable signal be communicated between fpga board and PC. But the problem from me,which I want the signal or message send automatically when vibration sensor be triggered and send to my phone. W
Your code will not work as uart is not properly configured. Also you need to test the response from modem before sending next AT command. See this link for uart code. #include #include #include #define XTAL_FREQ 4e6 __CONF

If you want to make a confirmation of OK, you need a uart for receiving char and store in a variable. After that u compare with another variable that has the expected data. Or you can search for characters to receive, eg 'O' or 'K', or 'O' and 'K', so you do not need to use the memory space to store variables to compare. This code I showed you, s

I am using BASCOM-AVR compiler ver 1.11.7.3 and when a DTMFOut command is executed the program starts from the beggining. I thought that there was something with software-hardware-frame stack but changing the values to maximum possible returned no result Even the MCSElec example doesn't work!!!!! When i used ver 1.11.6.7 everything worked nor
Hi, My recomendation never use hyperterminal for anything. My recomendation is WinTelix 1.1 or Telix 3.11 (DOS). Telix for DOS is better because you can use num keypad to send binary codes in Windows programs this doesn't work. For connection with uC uart you can direct connestion. Make sure that speed, number of stop bits and parity are mat
