picload

Hello everybody!

I'm making an application and I need to load the main program for a pic (16f877) because the program is always changing according to the requirements of the User. For my application would be great if the PIC could load the main program (. Hex) of a SD Card and start working. The User record the file. Hex on the SD / MMC card put on the plate where the PIC and PIC load the program and start working, you have q as I do that? I would like to help me! YAY!

pic microcontroller bootloader sd card

Here's a link to a commercial SD card bootloader: https://www.smallridge.com.au/#SD_LDR. It supports only PIC18F and higher, though. May be that's due to the fact that communication with the SD card consumes lots of resources.
