    PROTEUS 8 - SMT pad shown in software but not on real PCB

    Hi, i used Proteus 8 to design my PCB. recently i received my fabricated PCBs and notice that the MOSFET's drain SMT pad is somehow covered with the soldermask, which it shouldnt. i have asked the PCB house and they mentioned that unfortunately based on the given Gerbers that the MOSFET's...

    is it possible to install orcad 9.1 and cadence 16.3 in same system?

    Hi, i basically did the same thing, installed both OrCAD 9.2 and OrCAD 16.0 why? because for schematics i designed using v16. then for simple auto-route i used v9.2. then i will use GerbTool from v16 to insert logo and modify certain things such as changing the Holes of DC Jack into Slots...

    [SOLVED] dsPIC30F6014A - Problem with UART Receive, using MPLAB C30 Compiler

    Hi, for updates, i have been able to use both dsPIC30F6014A's UART1 and UART2. below is the functions that can be used for Transmit, Receive, and Send String: Examples of use: for Transmit // character 'a' will be sent through UART1 mCputc('a', 1); // character 'a' will be sent through...

    Calculate capacitance measurement between electrodes

    Hi, I have been able to simulate the electrical fields between 2 electrodes using COMSOL 4.2a, when one is given positive potential and the other is grounded. However, after so much trying i am unable to get the capacitance and voltage values on any points between both electrodes. Please help...

    [SOLVED] dsPIC30F6014A - Problem with UART Receive, using MPLAB C30 Compiler

    Hi guys, i have tried programming the dsPIC30F6014A to make the UART1 and UART2 to function properly for days now. 1) i started with using CCS C Compiler, successfully able to send and receive from both UARTs. the problem is however: - UART calls (e.g getc(), puts()) cannot be placed in a...

    Image Processing - Matlab

    nice. from there you can start counting the red pixels based on the RGB function, image(x,y,1:3)... where x and y is their coordinates while 1:3 will tell the RED, GREEN and BLUE values. since you want the RED pixels, then you can select your RED threshold values and count those pixels. count =...

    C++, GUI, Hardware interfacing

    Hi guys, i am more familiar to do all of the things mentioned in the Title (C++(code programming), GUI, Hardware interfacing) by using other software like MATLAB and VB6. however after years of experience it seems there's some slow computation problem for acquiring data from the hardware(serial...

    why there is 1K resistor after the capacitor? What this resistor called?

    i think it's the bleed resistor. A bleeder resistor is a resistor placed in parallel with a high-voltage supply for the purposes of discharging the energy stored in the power source's filter capacitors or other components that store electrical energy when the equipment is turned off - wiki. i...

    How demanding is the experience for working with PCI Express?

    i had a sales agent from National Instrument coming to myself to explain on DAQ system we are purchasing. he mentioned NI will be focusing on PCIe products in near future (recommending me to buy system that can support PCIe products). so maybe would be safe to say NI demands on PCIe is high?

    [SOLVED] Mistake in soldermask design: Bare grounding

    Hi, i've made a mistake in the soldermask design. as shown in the picture, the pads for the SMT tactile switch on the top layer is by mistake also made available for the bottom layer. 1) my question, is there gonna be any problem? in term of high-speed circuitry, is there any significant...

    Diffrence between pic 16f877 and pic16f887

    there's some difference. however, it is best if you already know what you want, highlight it to us, then it's easier to narrow the difference. example scenario: i need to sample analogue voltages from 10 different sensors simultaneously. then from there we can say that your PIC16F877A only...
