I am using a pic16F1827 microcontroller. I have written a c program that reads 2 sensors and saves the data. On the same breadboard I have an XBee Pro Digimesh adapter. I have the xbee wired to the tx and rx pins of the pic. I am wondering if anyone has an example of how to transmit some data to the xbee. I want to use API to do the (...)
you should be able to use printf() with a pic18 if you connect a PC to the usart 1. if the PC has a RS232 COM port via a MAX232 2. with a suitable cable, e.g. USB/TTL you need to setup the usart with a baud rate etc to suit the terminal emulator on the PC
Hello. I'm learning to use the UART/usart on a pic microcontroller, to interface with a computer for the first time. Every time I want to re-program the pic, this is what I do: Disconnect COM port from breadboard. Connect pickit 3 USB programmer to the pic. Program (...)
If you are new to gsm project then i recommend to use SIM300 module because there is lot of projects and help available on internet. And for pic uC, If you know how to program 18F series then choose any 20 or 28 pin uC or select 16F 20 or 28 pin which includes on chip usart.. pic16F877 is good for newbies and ready projects also available (...)
I have a pic18 microcontroller connected to a UART-to-USB bridge! I need to show the data on the EEPROM memory of the pic on my PC. what kind of software could help me? Use a serial terminal like putty, or mikroC usart terminal, or arduino serial terminal. There are many serial terminal softwares.
i suggest to use an small AVR (ATmega328) or a pic(pic18F252). -both ar low power (but it depends on the max frequency you will need) - i think you need a microcontroller with bootloader capabilities (most AVR and pics have that over usart) so you need to program just once and the use the bootloader inside (...)
I am poor in c-language but i have did it in assembly language in pic microcontroller. To convert the parallel data from PORTB to serial data i used the following algorithm, 1. Move the PORTB register to TXSTA (Transmit register of usart) 2. Once you place the data in TXSTA it start transmit data serially automatically. only you have to (...)
Yes why not. pic is enough to be use, you may use AVR and 8051 based controllers too, but code size must be depends upon the Program memory of controller, Let for example a microcontroller which have more than 8KB memory space with built-in usart is suitable for your project.
this is already discussed in the forum, you can do a search in forum. meanwhile refer this RS232 Communication using pic18F4520's usart - pic microcontroller Tutorial | eXtreme Electronics dont worry about the
Hi friends May you please help me with a c program of communicating 2 Bluetooth modules RN-42 using usart/ uart ( pic 18f2420 microcontroller) thanks
Hello, How to use usart module on gpsim? I have loaded this module and connected it's rx pin to the pic microcontroller's tx pin, through a node. After pressing the Run button all I can see is red marking on the pin. I don't see any transmitted character or terminal. I have tried by enabling console setting to true also. But no trace about (...)
How to receive and process the data in the desktop PC received via usart-RS232? The microcontroller iam using is pic18F4520. I tried installing RealTerm, but it's not working. Is there any way to receive the data into a web application, process it there and add the processed data to the database?
Hi.. I am using pic18F2520, for GPRS modem communication. Modem is successfully communicated through Hyper Terminal. Then i am trying with pic microcontroller, i am Sending "AT" and trying to get response but some time it is giving responce or not some time. and data is not getting correct. plz. give me some suggetion or if any one has (...)
Dear friend, You can read gps data by using usart. GPS data Format: NMEA data
Hi, For this purpose you have to use usart or UART module. This is present in 16F877A. Like Jerin said, check the datasheet and also check the Microchip Mid Range microcontroller Reference Manual where all details of UART/usart are explained in detail. You also did not mention which language you use. Your compiler may have inbuilt functions (...)
There are a lot of MCU's that can do that. A bootloader is first programmed in the chip and then the same software can be used to flash the microcontroller thorugh other interfaces, usart being the most popular interface. Most of the pic microcontrollers and a lot of the AVR series by ATMEL and NXP semiconductors LPC (...)
you don't have the option of USB with pic18F452, you can use serial interface, read the datasheet about the built in usart module, you will need MAX232 IC with some capacitors for line coding. also the parallel port available, just you will program the parallel port pins and make it read/write from any GPIO pins of the microcontroller. for (...)
Use the 16F690, the '84 is a pre-historic chip! Also, you would only be able to connect to the phone if it has a RS-232 / usart somewhere on the connector, if you want USB be prepared for a pic24F and lots of coding headaches
The description on the Microchip site is very straight, there will be no doubt if you read the pages: picKIT2 is a pic programmer (with some additional features) and the picKIT SERIAL ANALYZER is a tool to test serial communications protocols (I2C, SPI, Microwire, LIN, usart). Both use a pic (...)
Yes, it is possible. I have connected a pic 12F675 (which has an A/D converter) to a pic 16F628 (that does not have an A/D converter, but it can control a LCD) in another board, via serial communication (usart hardware implemented in the 628 and software implemented in the 675). Some pics have parallel ports (e.g. 16F877 (...)
Hi All , can anybody please post good example for any usart checksum method for pic18f , or any explination how can this be done , thanks alot .
hello all: i am now working on a project making a manual robot, and i want to control the robot using PS joypad which i think it sends data serially, so i want to know if i can interface the PS joypad with pic microcontroller as i know that the pic 16f877 microcontroller has a usart. please if anyone can (...)
please , I need help Any body show me how to interface pic microcontroller with PC using usart.
Try use IC MAX485 to interface your pic verse the serial peripheral. The pic microcontroller will have to be programmed to send out serial TTL signal (usart). This TTL serial data can be converted to RS485 using MAX485 IC. It converts TTL serial data into RS485 standard.
Consider implementing an interrupt driven bit-banged serial I/O subsystem to supplement your hardware usart module. As funnynypd mentioned, you don't have to poll the pins. Simply use interrupt-on-change (IOC) on the RX pin to detect the start bit leading edge then use Timer 2 interrupts to clock in/out serial data bits at 104 usec intervals (960
pls help... how can i receive 3 bytes of data from pic16f877a microcontroller to PC using visual basic 6... when i write 3 consecutive bytes using usart, i only read special characters from vb6... anyone can help me with my code? Private Sub MSComm1_OnComm() Dim sData As String If MSComm1.CommEvent = comEvReceive Then sData = (...)
You will need a microcontroller I use AVRs , pic is another option U will need to make a real time clock on ur microcontroller if u want to hv a stand alone unit otherwise PC clock can be used. As for memory and storage part AVR has got inbuilt memory and u can easily transfer data to PC for displaying using usart As (...)
