kinda curious..... does that pixycamera have a set of commands ( like Hayes modems ) that you can use or do YOU have to make the entire 'driver' for it ??
If the 'command set' is built in, then a mu ... |

This is a key to understand about the different 'nature' of microcontrollers.
The PIC stands for 'Peripheral Interface Controller'. It is _not_ a general
microcontroller. It was built to be a sim ... |

Think about it. Even a tiny picture will be perhaps 192*128 pixels. Even
in B&W, one byte per pixel. Needs then 24576 bytes to hold just a single
frame. The 877 has 192 bytes.....
Even if yo ... |

Pretty sure this is a school assignment Jay. This bit:
...how do I choose my microcontroller (i.e the sensors feed this much data back in 1 sec and the MCU has this much memory therefore it can han ... |

Do you HAVE to use a camera as the white line sensor ? It's tremendously far more complicated both in hardware and software to be used as a 'white line sensor (wls)' !
One of the simplest wls is a ... |

That is nice, since you are not dealing with the image. Problem is, even for
very small images, the PIC in general does not have the memory to cope
with images. With that you program the camera to ... |

PIXY2 camera: https://pixycam.com/pixy2/
I have one, but I never tried to interface it with a PIC. They do offer the code for Arduino and Pi.
Thanks, for your speedy response. Yes, I am using a ... |

Key. Add 'L' here:
set_pwm1_duty(100L);
Problem is that the duty code has two operating modes, dependant on
whether the value passed is an 8bit value or a 16bit value. If a 16bit
value is p ... |

Hi I'm using PIC16F877A (external crystal 20MHz) to implement PWM on CCP1.
I tried many cases using the same code and calculations, all works but this one particular case where f_PWM = 100kHz, T_PWM ... |

haven't read the MP3 datasheet but...maybe it doesn't like your 'checksums', and refuses to play ??
Yeah it's written in the pdf how to find all other bytes and their meanings except for the checks ... |

It can't take another command, till it has finished the one that is playing
So just wait for the line to go high, before you next call the send_data
command.
Hi, thanks for your rapid response. Y ... |
