You can't send rs232 over these devices. You will need to send a balanced bit stream which can be converted to rs232 by a PIC at either end. You can use either PWM or Manchester encoding to balance yo ... |

Hello all,
I have a problem sending data to the PIC rs232 port from an external application. If I try and send anything more than 3 or 4 bytes in a stream, the INT_RDA hangs up and the PIC won't ac ... |

I'm reading the PIC ADC in 10 bit mode and storing the result in an int16 type. I need to break up the 10 bit value into two bytes so I can send them over the network. At the other end I need to combi ... |

Hi all,
Quick qn., the LCD driver that ships with PICC uses a contiguous port to control the display. The code maps a struct over the the port like this:

Problem solved!
I changed the SPI setup code from this:
setup_spi(SPI_MASTER | SPI_H_TO_L);
To this:
setup_spi(SPI_MASTER | SPI_H_TO_L | SPI_XMIT_L_TO_H);
And now everyt ... |

I tried changing the setup_spi() to use the spi_l_to_h flag to invert the clock, but now I get nothing back from the MCP2515. Is there another way to implement the clock change you suggested? |
