Here's some interesting info for you... I tested out this cool bootloader that shows as a device in "my computer". yes, cool... but maybe not so practical (only because it is slow). http://direction.scene-double.com/2008/07/08/usb-msd-bootloader-for-pic-microcontrollers.aspx
It came with a hex file for 18f4550, so I wrote it to my PIC. Then I plugged in the USB port. Windows sees it in "my computer" as a removable media device. On it, there are 3 files: 1. CONFIG (this file contains the PIC's eeprom data, you can modify the PIC eeprom here) 2. FW_10 (basically contains your hex file) 3. BOOT (delete this to run your hex file, the device will disconnect from your system) Press a button at any time to load the bootloader and connect the device to your system again. It came with a sample program that does work. The document says if you make a hex file, it may start at address 0x2400 This is not for an SD card, but anyways it shows in "my computer" as a storage device :) Matt. -- You received this message because you are subscribed to the Google Groups "jallib" group.
