| Greetings,
I have read the posts in the forum as this seems to be a common theme. I have an ISR which has a division and multiplication which does not seem to be avoidable. Is there a way to ... |

| Greetings,
As an off topic to the already addressed problem, PCM programmer correctly lists the standard NMEA-0183 baud rate at 4800. Another high speed version of this exists and is 38400 baud. ... |

Adding extra logic to your control might assist in your application. Suggestions: Temperatures change very slowly (relatively slow compared to a uProc). Updating your PID algorith ... |

| kd5uzz,
I'm with newguy on using a CAN bus. If you could modify your hardware/software slightly to use SPI, you can interface a standalone chip like the MCP2515 from Microchip. You would stil ... |

| Howdy ROBOTICAR,
Many of the GPS receivers on the market use RS232 and/or bluetooth. The protocol usually follows the NMEA 0183 spec. If you like CAN, there is even NMEA 2000. The NMEA 2000 rece ... |

I checked one of the datasheets and I do not believe the dsPIC33 has a CANSTAT register (or bit). One reason for the INITIALIZATION_MODE entrance to fail is if a transmission is ta ... |
