I meant there wouldn't be anyone physically at the device. The device has internet connectivity so the HEX files can be transferred that way.
This would be a good kickstarter project. Any takers?
I don't have any experience with memory cards outside of my digital camera etc but can't you use it basically as a "raw" memory simply by NOT formatting as FAT or whatever. I mean the protocol is...HenrikOlsson Today, 11:56
a winbond flash chip (w25q32bv or similar) mounted in a sd shell would be nice . you could have the utility of a sd card slot without all the overhead of a sd fat-16 file system .richard Today, 09:21
You're being quite vague IMHO, secret government project? :-)
You say no human intervention....so who's deciding when to load the new firmware?
Abyway, in theory yes. As long as the PIC can...
A PicKit2 wouldn't work. If another IC had SPI, RS-232 or some other communication protocol that would work, could that IC load the HEX file onto the PIC without human intervention?Christopher4187 Today, 05:18
To add to Henrik's remarks. A PicKit2 will do the same job and the USB supply can come from either a USB "brick" or a USB power bank.
So you DON'T want to use either a computer, SPI or RS-232, is that correct? Or do you mean that you DO want to use SPI or RS-232 just NOT from a computer?
This isn't actually bootloading but the...
I searched the forums and found a little bit of information but nothing that fits exactly what I need. Is there a way to load a hex file into an 18F without the use of a computer using SPI or RS-232?...Christopher4187 Yesterday, 02:13
