40Mhz, I suppose you want to use a 18F? Witch one? How will you transmit your data? I mean, by a discrete HF transmitter or with a 'plug and play' module (like Telecontrolli or Aurel ones)? What is the voltage and current consomption of the motors? Please, be explicit if you need help. It's not fun to extract carefully each word from you... (Sorry if this sentence isn't that good, I'm not sure if it can be translated...)
yes I want to use a 18f, I do not no how I will transmit my data hopefully you could help me.
the voltage is 6 to 12vdc and I do not no the power consomption at this time.
I'm working on a similar project by now. I'm building a semi-autonomous vacuum cleaner robot. I'll transmit data by a serial liaison (the USART of the Pic). I'll use two Telecontrolli module for the RF part. It's cheaper and it cost less than doing it yourself. I'm using a PIC 18F452 at each end (one on the emitter and one on the bot).
