    Re: start working with lpc1768 - hardware

    If you want to make your own board it makes sense to check the datasheet and a couple of schematics of existing development boards and see what they use for supplies etc.

    Here is an example https://www.olimex.com/Products/ARM/...66-STK-SCH.pdf

    Re: start working with lpc1768 - hardware

    I've seen blueboard schematic.
    it makes a good Idea on the minimum requirement for powering up micro
    the most important part is its vcc and gnd by using 3.3v regulator(I prefer lm7833 other than what schematic says)
    using low pass filters to isolate high frequency noises, effecting mcu
    configure vref+,- vdda,vssa for adc - also use low pass filter
    crystals should be configured as in the schematic
    inductors should be 100uh(not mentioned)
    other pins(with label) are jtag pins, required for jtag debugger
    bad -- imam -- good
    everyone has an imam , sometimes our father,king,friends,...
    they are the cause of fault or success so let's choose the best
