Igor, In a system I designed and built for in house testing where I work, I had a need to address several slaves. In this case it was 8, but the same idea can be expanded. What I did here was to reserve 3 pins on each slave PIC as address pins. In the hardware at each

Hi, I hope someone can help with a little problem I have!=20=20 I am trying to get several 18F PICs to communicate over RS-485.=20=20 I will outline the basic idea behind the problem so it at least=20 makes a bit more sense!=20=20 I have several chips communicating via I2C to a local 18F PIC which=20 is then relaying the data to a master controller(18F PIC) which is=20 then passing ...

Hi All: I have a Pic16F628 chip which I want to be able to communicate with my PC via a RS-485 line. I want to use the USART on the chip and a DS75176 Transceiver in a Half Duplex setup, but my problem is with what to control the Read Enable or Transmit Enable pin on the DS75176? If anyone also has a simple schematic and code that they don't mind sharing I would be grateful. Regards ...

Where can I find information on programming a PIC using the UART and decode address and other data?? ( and NOT 9th bit stuff ). Ive read the Microchip sheets but not clear on what Im doing yet. I want to use a PC and a 485 network to poll several pics, each with its own address. Use is controlling signals on a model railroad. Any help is appreciated! Trying to learn with a middle ag...
