PIC16F1947 - Handling Rs-485 [solved] - RckRllRfg - 2011-08-07
Hi Everyone -
I have been working with the PIC16F1947 for the past 2 months. I have a program now up and running that is using both UARTS. This program was written in C using the CCS compiler.
I would like to add the ds30 bootloader to this device.
I am planning on communicating with several PIC16F1947 PICs via RS-485 Half Duplex
The transceiver being used is a Linear LTC1387IG which has several control signals including:
RX Enable RXEN
TX Enable DXEN
485/232 mode
OUT-ON
In the settings.inc file, I see the provisions for the TXENABLE. The question is –
1) Do I need to have TX out from the PIC to the source computer?
2) If I do need to have this TX back to the source, can this handle some addressing given that I will have multiple units on the RS-485 line?
Any guidance on this would be greatly appreciated.
Regards -

Hi,
1) I am not sure what you mean here. The PC needs to receive information from the PIC.
2) ds30 Loader does not handle any addressing and/or 9-bit modes.
