The task is to program a PIC16F887 or equivalent to read DS1990A serial number. If the serial number matches a pre-programmed serial number, do the followings for 30 seconds - 1) display the serial number on HD44780 or equivalent 16x4 LCD, 2) provide output to an output pin (say to turn on an LED) and 3) count the number of times an input pin reads an input, 4) display the counted number on the L...
We have an implementation of a raspberry pi communicating through I2C with two PICs. After working for some time (hours, days or weeks), one of the PICs or both are no more detected by the pi. Booting the pi does not solve the problem. We need to boot the whole system so it works again. We need expert assistance in I2C and raspberry pi to solve this issue, since we need this communication to be s...

I need a chain or arduino's, maybe more then 100 Arduino's even. I am not sure which protocol I like to use. I think I2C and also RS232 are options. Each Arduino needs a number of digital IO at least 16 or so. Each Arduino must be able to send short messages to the neighboring Arduino. The whole chain must be controlled by a pc.
The purpose of this lab is to design a VGA driver to display 256 different colors on a monitor. Two timing signals are generated in this system, vsync and hsync to synchronize the plotting of vertical and horizontal pixels, respectively. The color data of each pixel is generated using an 8 bit counter whose first 3-bits are for red, next 3-bits are for green and last 2-bits are for blue color data...
i want to make two pairs of wireless display by using rf modules so that each individual display has its own data data dhould not be coincide with each other
in the project there is a basic game. There are some walls placed vertically and an object slides and try to avoid crash these walls by using up and down buttons on FPGA. it is not mandatory to be a complex project. I need to have in a week.
