Q: Bootloader over RS-485 / Modify bootloader?
2004-12-13 by ateichtmann
Hi, i want to update my application with the bootloader of the LPC2106 over a RS-485 bus. Unfortunately, it is only a half-duplex bus and the RS-485 driver-ic has to be switched between rx and tx. So my questions: Does the ISP programs (Philips, other...) and the bootloader need full-duplex? Is it possible to modify the bootloader (to switch the RS-485-IC between rx and tx)? Thanks for all hints... Regards Arvid
