Hey all, I am working on another R/C project and need to be able to adjust a 5K 3 wire pot via Pic. I have been looking at digital pots and see that they have 2 types I2C and SPI. What does this mean? I just need to be able to adjust the pot via a Pic from 0-5K with no fancy extras. Can someone help me? Thanks! Neil Smith

Hey all, Need some help in my latest endever. I am trying to drive a MCP42010 digital pot with a Pic16f628. I have read all the data sheets and still stumped. SPI on the MCP42010 uses CS(chip select), SCK (serial clock), and SI(serial date input). Which pins corospond to these on the PIC? Is it right in front of me?? LOL Thanks, Smitt

Dear All, ? Need Help! ? I?want to know whether the chips designated "LF" (low voltages devices, Example :PIC18LF2580 ) can be used as normal "F" designated chips( Example: PIC18F2580). I know the vice-versa is not true.?Whether all the ports,I2C,SPI,SERIAL n so on?etc ?of "LF" chips? function as standard "F" chip at +5V. I mean are there any restrictions or limitations. Can i replace PIC18F...

i'm starting on a project that requires async serial input and sync output. I just wanted to make sure the 16f877 can do both of these at the same time. I think i am going to use SPI (instead of I2C) for the sync output and USART for the async input. does this sound like a

I'd like to know how one goes about programming a serial flash data chip such as the AT25/45 or SST25 8pin dip? These chips have an SPI interface. But can I simply use an off the shelf EEPROM programmer like the Olimex PG2? I have few programmers in my stock bin Olimex PG2 with 8pin EEProm socket. Warp13 Kanda ISP (with 5x2) socket. If you have recommendations or tips, please...
