We use oki c711 laser printer... this is a comum laser printer which is based on sheets feed, like A4, Letter, etc page sizes. We need to modificate firmware of printer that when we sent for example 10 copies of document to print, the printer doens´t ask for load next page sheet, and just continue to print on continuos roll. If you have any doubts, I would appreciate to explain better.
I am working with modules ESP8266-01 and SIM808. Both can send HTTP post with sucessfull, but is required HTTPS. I need a freelancer that already have sucessfull on deploying Arduino with HTTPS (ESP8266-01 and SIM808). No fingerprint certificated method will be accepted, because the certificates are exchanged each 1 year.
Description is incomplete, please refer to the PDF file provided for a more detailed understanding. PLEASE Show all work, steps, and explanations [login to view URL] are given a 4-bit SAR ADC as shown. The reference voltage is 3.3 V, the input voltage is 2.427 V, the comparator has no offset voltage, and all capacitors are perfectly matched. Make a table indicating the position of each switch (including the reset switch) and the voltages vx and vout for each step in the conversion process. What is the complete ADC output word? 2. In this problem we will look at a 2-bit MDAC used as the first stage of a 14-bit pipeline ADC shown below. As will hopefully be clear by the end of this problem, the first stage of a pipeline ADC is typically the most critical. For each clock cycle, half of the clock cycle is spent sampling, and the other half is spent in the conversion and residue amplification process. We will assume that the amount of time for the 2- bit flash to make a decision is negligible. We clock the ADC at 10 MHz sample rate. a. How accurately must the output of the 2-bit first stage settle so that the ADC maintains a 14-bit resolution? How many time-constants do we need to wait to settle with this accuracy? b. What GBW does the opamp need to settle with the accuracy of part a, and the given clock rate of 10 MHz? c. If the opamp has finite gain, this can also limit the accuracy of the settling. What is the minimum opamp gain needed to guarantee the output is capable of settling with the accuracy found in part a?
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 while the synchronization signals are generated. This way, as the counter counts, 256 different color combinations are displayed on the screen one after another. This counter is implemented on the FPGA board

I need programmer to help me finish up an application for a STM32F4 Discovery. The application must read samples from the onboard MEMS microphone and run FFT. It will then report the frequency,magnitude values over USB. The existing code has USB running as custom HID and the actual microphone sample acquisition and transmission must be implemented. Existing code uses gcc and STM Cube HAL drivers and such it would be great to continue with these tools. Need source code and build binary file.

Project Description: The project aims to assemble an Electronic module to detect equipment fall and activate the solenoid valve once the recorded data go out of set Orientation parameter. The equipment will be mounted on the base, the module will be powered on by the Push to Start switch. Arduino 3 axis Accelerometer module will be used to detect acceleration, orientation, and impact. These data will feed to Development Board for real-time analysis. The individual feed ( Acceleration, impact, and orientation) compared with the set value, if the value is out of range, then the board will give a 5 V or 12V output to Solenoid valve to open/close. Some additional features. 1. Battery low Voltage light indicator. 2. Solenoid valve opened on impact and closed on impact. Note: Arduino 3 axis Accelerometer module codes are available online in C++.

I PCB controller with capacitance touch screen that will control functions in a display mode. i will send you a schematic to lay out PCB which will have just top and bottom traces per schematic. The board can be three layers. envelope size of board must be 3 x 4 inches with micro USB to load software which we will do. You lay board out to schematic and use parts that will be supplied as well in a parts list. If additional parts are needed per the schematic, must be bright enough to reconcile the differences and update parts list. Will need a working prototype that we can upload our software into from micro usb. All documents to design and layout PCB will be supplied. You will package and send PCB along with touch screen per the suggested part number in docs. We will design the enclosure to fit with the envelope size stated above. If PCB real-estate is too small, we will allow you to add to envelope size length wise about .5 inches and width wise .5 inches. Side to side will be max 4 inches and front to back will be max 3 inches. total board height with components on top and bottom will be a max height of .25 inches. Additional height will be for capacitance touch display per the part number assigned which is based on already existing prototype. Will send files later once we establish time frame. This unit will also have an active state of only 10 seconds if touch screen is not accessed within that time and will go into a sleep state, only to be awaken when touch screen is touched again for data access. This is the second time that I have submitted this job, but had to hold off for scope and design changes. The board will also need 4 mounting points nearest the corners of PCB, typical mounting points in the industry with pads. The pads will not be needed for grounding. PCB should be self contained with grounding and ground planes only if necessary. weight is an issue and don't want something that can be carried in your pocket to be too heavy

I am an avid outdoor enthusiast, I like to take my Tacoma on outdoor/overland adventures. Part of this is managing the air pressure of the tires on the truck. While offroad I need to drop the pressure of the tires down to as low as 5lb per tire or all the way back up to street pressure of 40lb. The pressure of these tires would need to be adjusted depending on the terrain. I'm looking for help to build a controller module that would allow the automatic inflation or deflation of the tires to whatever pressure I define. I am looking for help to take off the shelf parts to create a controller module. This module would need to interface with 1) pressure transducer to read the current air pressure 2) Air pressure solenoid: this would be used as an output to interrupt the air flow when the desired air pressure is achieved 3) Secondary solenoid: to be used to allow air to escape when deflating the tires. There would also need to be an LCD control panel that would allow you to 1) Monitor current pressure 2) define intended air pressure via buttons (up or down) or via rotary knob 3) view defined pressure set with #2 4) Select between an inflation and deflation modes. The control of the air compressor should be considered independent of this project and should be assumed that the compressor will automatically turn on/off when the pressure is achieved.
