  • I have an RFID reader which supports EM4100 compatible read only or read/write tags. What I want to know is that can these SF RFID tags be identified by the reader that I have?

  • I have bought an LPC2148 development board from a local company which also has a SD card slot and the uC has a bootloader that burns the micro through UART0. Having read the above article, my hands are itching to try to burn the code in the uC using USB by overwriting the existing bootloader.
    Now my question is, is there any way I can backup and later restore the original bootloader if things get messed up in trying to overwrite it?

    1. Incase I win some money, can I order from one of SF’s distributors or do I have to order from SF directly?
    2. Is the cost of shipping included in the prize money won?

No public wish lists :(
