 Forum: General CCS C Discussion Posted: Sat Oct 19, 2013 7:20 pm Subject: Simple interrupt code doesn't do anything |
| Hi Again !!!
I've been trying to make a simple interrupt code but the microcontroller doesn't do anything, why!!!!! it just is in the while loop, I tried with the RB1 interrupt but nothing, I hope ... |

OMG!!!! PCM programmer  I'm so sorry. I'm wrong.
Integer of 8 bits just can represent till 255 :S. I can achieve 8 MHz but It's just a trial, It seems the PIC is working now adding that ... |

Hi PCM programmer  !!!!
Thanks for your reply. The pic use a 4MHz crystal for the USB module, and derive the 48 MHz. Ok! I'm going to use the counter CD4040 to divide the max Frequency (8 MH ... |

| Hi Ttelmah !!!!
thanks for your reply, I think your way to do it is better. I'm going to use the 26j50, low consumption, high speed, it's great!!. Yeah the ADS1254 has its own clock source with c ... |

| Thanks FVM and Ttelmah.
Yeah it's a Master. The SPI behaivor is : when the data it's ready from the external ADC (as gently PCM programmer said it's ADS1254) the interrupt is executed. The A ... |

yeah I've got the information above the load cell. It's got circuits to avoid noise, the amplifier's going to be designed with a monolithic of ANALOG DEVICE. About the ADC I have the C ... |

Ok I'm going to forgive the PWM and count MCLK cycles. The key is on the function DOUT/DRDY. About that pull up resistance all I have to do is connect it, from D ... |

| The ADC is ADS1254 who needs a external clock signal.
The pwm from pic18f4550 generates the clock signal. I'm going to use SPI communication to receive the data, but as the data sheet says I need to ... |
