Hi, I want to make a CAN bus demo development board, for which I would request for suggestions for suitable micons from pic. I have following criteria. 1. Should be DIP ( greater than 28 pins) 2. Should have decent RAM (8K) 3. Should be programmable through picKIT 3. 4. 8/16 bit 5. Is available in India (online) :roll: Also please (...)
HI guys, in the description of the seems confusing the way they describe it and the A0 to A5, apparently A1 to A
hi. i need an example to communicate between 8 pics as slave and one as master. Every slave have an led light and i want to make turn on or off from MASTER instruction. i want to use pic16f877a microcontroller for all (master and slaves). I have little bit practice on CCS compiler if any body have this code then it well be very help full for
Hey I am doing a microchip IC based controller project wherein i need to send some info/data from 1 pic IC ,just for illustration ,lets say IC1 to IC2 and IC3 at a given time and if need be send a new set of info from IC2 to IC1 and IC3 and similarly from IC3 to ICs 2 and 1. So in other words all the ICs interconnected by a bus are peers i
Hi sangeo, the pic IO-extender offers 16 IOs per package and three can operate on the I2C or SPI bus( ). If you use the 8 bit wide 74HC165 you need to decode the I2C/SPI bus and select the in series connected six HC165. Than 6x8 bit cloc
i have 2 max 485 ic connected to 2 pic micro controllers one controller transmits and another receives half duplex communication, both the controllers operate from different power supply the ground is not common. my doubt is in the tx side i have one max 485 with a and b bus terminals, and rx side i have one max 485 with a and b bus (...)
Hi, Is it a USB HOST? Can you tell more about it? if the first post #1 a pic18F47J53 was mentioned which only supports USB device not sure what the USB is for ? if the project is to received data from a parallel bus why not interface the bus directly to the pic (possibly thru level changers)?
in an industrial machine control and monitoring system with 50 + machines we used 10baseT wired ethernet - well proven cheap reliable technology which ran for many years and is still operational used a pic18F97J60 (with onboard 10bastT interface) - these days we would use a pic24 or pic32 protocol used was UDP talking to a server written in
Here I am posting mikroC PRO pic code for multiple I2C LCDs. With this you can have a device like DS1307 of I2C bus and also 8 I2C PCF8574T based LCDs. I didn't post this in my previous thread in DIY section because its title had CCS C Project but this is mikroC PRO pic project. I have used these I2C LCDs
read the page number #43 at above link sample code is given for pic controller modify it according to your pic controller.
Need a diagram of the connections to really assess. But here are some general issues with connecting with 15 meters of wire... If you are looking at 4 digital signals from the 7404 then you should make sure you have a common ground between 7404 and the pic. If you didn't do that you will likely get fluctuating readings as there could be differenc
There aren't much I2C devices that support 3.4 MHz "Hs" mode. pic processors e.g. don't.
That pic18 tutorial I mentioned also has a page on the function of I2C and also a project using the I2C debugger in
Hi, I'm using pic18F2580 and MCP2551 CAN transceiver. My goal is to implement basic CAN bus monitoring program to capture CAN's frame ID, data length and data bytes. I use logic analyzer and can see that CANRX pin on pic is continuously receiving data. However, the RXFUL bit of RXBnCON register has never been set in my program. (...)
Hi i am interfacing pic18f4550 with DS1307 RTC .Firstly it was showing Correct values on Proteus Simulation however after few minutes it showed a random value then switched back to correct values now after some time it again showed random value without switching back to correct one. when the display was showing random value the data in clock panel
How is the DDS connected to the pic? I wire mine through the SPI bus. You would then send the 5 bytes using the SPI module.
Hello to all! I'm new here and I am making a project for connect 10 ds18b20 to a bus and public to internet with board pic-web - rev 3 - pic1867j60 on board. Who can help me with some code for SEARCH-ROM? some code for start my project with a working base. NB: I am using MPLAB with c18 Thank' a lot to all !!
hey guys , i want to control 3 devices and send them the same data in the same time , the devices may or maynot reply. (can be enabled or disabled ) what i am sending is just a string every 1ms . can i connect the three devices to the same UART port ?? if not why ? and what if the devices are only receiving and the main controller is sending .
hi ALL can some one guide me to some projects using pic microcontroller and can bus plus some advanced can bus tutorials best regards Controller Area Network Projects, Dogan Ibrahim
Hi Can anyone please tell me whether a LIN transceiver(MCP2003) is required in an interface between pic micro controller with EUART and LIN bus in a vehicle? If it is required, then what is the use of EUART in uc for interfacing with LIN bus? Can I use the regular UART?Will the whole circuitry compatible with K-Line communication? My (...)
