    Above is the design of the RCD programmer. It can be found at the site of Feng3 (Three is pronounced 'san' in Japanese so it should be Feng San): feng3.cool.ne.jp/en/rcd Oh Feng charges his main capacitor in the negative TxD phase and when he turns TxD positive, the voltage is roughly doubled so this design will work with laptops and similar which have +/- 7 Volts RS 232 levels.

    Operation is rather straightforward. But Feng took better care of protecting RB6 and RB7 by means of the diodes D1 .. D4. RB7 feedback is done without a transistor. It seems to work. This would be my preferred design, to be honest.

    RCD Programmer

    I believe that the "JDM Programmer" is cheap and very useful PIC Programmer. However, since "JDM Programmer" cannot control VDD, the algorithm "VPP before VDD" is inapplicable. Programming to the latest device from this reason may go wrong when using CONFIG settings as "Internal oscillator" "MCLR OFF". These devices are given power from the "JDM programmer",and execute program code. An error may come out by verification, or it may become impossible erasure and become impossible re-programming . In order to solve this problem, I designed a programmer based on the "JDM programmer." Since this programmer was made of resistors, capacitors, and diodes, I named this the "RCD Programmer." "Hardware settings" of IC-Prog are the same as the "JDM programmer."
