Ahmeds contribution EJS simulations EJS Simulations modified by ahmedelshfie. Two Channel PC Based Oscilloscope USBInroduction. More and more experiments are now PC assisted. Also conventional acquisition systems are very expensive. Since portable  PCs are today common and a USB link is a better solutionhere we present an oscilloscope using USB port of the PC that operates at up to 1. Hz with 1. 6V input voltage. It has much more improved features than the PC based oscilloscope . The oscilloscope uses IC PIC1. F2. 55. 0 from  Microchip as the main controller, which makes the oscilloscope compact as there is no need of additional power supply for the entire circuit board. Circuit description     At the heart of this oscilloscope is USB2. PIC1. 8F2. 55. 0 from Microchip. You can also use  IC1. F2. 44. 5 in place of PIC1. F2. 55. 0. Specifications of this microcontroller are Features of 1. F2. 55. 01. Up to 3. B of flash memory, 2k. B RAM and 2. 56 byte EEPROM2. Extended instruction set optimised for C compiler3. Single supply serial programming and easy debugging. USB1. 1 and 2. 0 from 1. MBs to 1. 2 MBs. Isochronous, bulk and interrupt transfer modes. B of access RAM usable with 3. Multiple oscillator and power modes. From internal 3. 1 k. Hz to external 4. MHz with PLL2. Possible software switching between run, idle and sleepmodes. In sleep mode, current is down to 0. A. 3. Wide operating voltage range 2. V to 5. 5. V. Useful for battery. Complete set of classical peripherals. Several inputoutput IO ports, four timers with capture2. Synchronous and asynchronous enhanced modules. Streaming parallel port. ADC module with up to 1. This microcontroller has a USB2. CPU running up to 1. MIPS. Other Projects. Avobe Schematic shows the circuit of the two channel PC based oscilloscope. MCP6. S9. 1 from Microchip Technology is an analogue programmable gain amplifier that is well suited to driving analogue to digital converters ADCs and an analogue input to a PIC microcontroller. Two MCP6. S9. 1 programmable gain amplifiers IC4 and IC5 make it possible to choose the input ranges for each of the two channels, by selecting a gain from 1 1 to 3. The amplifiers are small, cheap and easy to use. A simple three wire serial peripheral interface  SPI allows the PIC to control them through  pins 5, 6 and 7. The MCP6. S9. 1 amplifier is designed with CMOS input devices. It is designed to not exhibit phase inversion when the input pins exceed the supply voltages. The maximum voltage that can be applied to the input pin is 0. V VSS to 0. 3. V VDD. Input voltages that exceed this absolute maximum rating can cause excessive current into or out of the input pins. Current beyond 2 m. A can cause reliability problems. Applications that exceed this rating must be externally limited with a resistor to the input pin. VSS and VDD. The voltage at this pin shifts the output voltage. The SPI interface inputs are chip select CS, serial input SI and serial clock SCK. These are Schmitt triggered, CMOS logic inputs. The only disadvantage is that these amplifiers accept only positive signals. Thats why voltage shifting amplifiers LF3. IC2. A and IC3. A are used,one each for each channel input see Fig. The LF3. 53 is a JFET input operational amplifier with an internally compensated input offset voltage. The JFET input device provides wide bandwidth, low input bias currents and offset currents. This voltage shifting amplifier results in a high input impedance and an attenuation factor of 1 4. A 1. 6V input signal is then shifted to the. Astro Saber Cps. V range when the programmed gain is 1 1. Two halves of the LF3. IC2. B and IC3. B are used as voltage followers to provide a low impedance shifting voltage Vref to the programmable amplifiers. This voltage must be precisely adjusted with two 4. V level on the inputs of IC2 and IC3 when the input signals are grounded. Because LF3. DC DC voltage converter ICL7. IC1 is used to feed 5. V to LF3. 53. With its small 8 pin DIP package, it needs only two polarised capacitors. ICL7. 66. 0 can be replaced with a MAX1. The MAX1. 04. 4 and ICL7. CMOS switched capacitor voltage converters that invert, double, divide or multiply a positive input voltage. These are pin compatible with the industry standard LTC1. Overview of the universal serial bus. All the data is transmitted on the DD symmetrical pins using a variable bit rate. The position of a resistor R1. D or D allows you to choose between the full speed 1. Mbps and lowspeed modes 1. Mbps. Note that the IC1. F2. 55. 02. 45. 5 devices have built in pull up resistors designed to meet the requirements of low speed and fullspeed speed USB. The UPUEN bit UCFG4 enables the internal pull ups. In this project, R1. External pullup may also be used. The VUSB pin may be used to pull up D or D. The pull up resistor must be 1. USB specification. The PIC software. The program for the microcontroller is written in C language. MPLAB 8. 7. 0 along with MPLABC1. The software tools can be downloaded for free from website www. Based on Microchips application notes, the program for the chip is centered on a main loop continually polling the USB transceiver state. This loop never stops and each USB operation is done in one pass. All operations are initiated by the host the PC, which ends a 1. The first command byte determines the chip actions. The four possible actions are 1. Command 8. 0h Clears the EEPROM calibration memory. Command 8. 1h Receives parameters, and stores the gain error compensation for the two channels. Command 8. 3h Initiates a zero calibration sequence of the two chan The first command byte determines the chip actions. The four possible actions are 4. Command 8. 0h Clears the EEPROM calibration memory. Command 8. 1h Receives parameters, and stores the gain error compensation for the two channels. Command 8. 3h Initiates a zero calibration sequence of the two channel. Installation of the USB driver. If everything is fine, plug the oscilloscope with a USB cable to your PC running Windows 9. SE or higher version. A new hardware detectedUSB2 Mini. Oscilloscope  dialogue box must immediately appear on the screen. NOTE The driver for this oscilloscope is not for windows 7 or vista. Now you can start the driver installation process. To download drive click here. The goal is to select a good driver mchpusb. Dont let Windows take a generic driver by default. When you are done with installation, go to device manager and check whether USB2 Mini. Oscilloscope is under other device in view devices by type option. Otherwise, repeat Steps 1 and 2. User interface program and operations. A user interface software written in Visual Basic 6, called Oscillo. PIC,. You can download this sofware click here to download Run the set up program, This will automatically install the Oscillo. PIC user interface program. Various settings for operations are given in the following menu bars. Inputs Selects the active channels. Sampling Sets time base and number of samples. Trigger Sets the triggering condition. Cursors Selects horizontal or vertical cursor positions. Num Shows numerical  sampled values, with an export command text file format. Config Configures gain and offset errors. Calibration is to be done as described below before reading the output signals on the monitor screen by clicking channels calibration under config menu bar. Feed the input waveforms say, sine, rectangular, sawtooth, etc from the source.
