Forum: BASCOM-AVR Posted: Tue Mar 26, 2024 6:53 pm Subject: Re: UART buffer ISR flags |
Does command INPUT after reading buffer set the flag to zero?
Input waits for data terminated with CR/LF or whatever is defined by Config Input.
Why should it clear the RXC-flag?
RXC is only set, ... |

Is there any meaningful advantage to this method compared to using a standard 2d array in regards to execution speed?
Your unrolled code executes in the statistical mean slower than calculating the i ... |

I was able to verify that PULSEOUT does not work on the PORTH.6 port
You are correct, neither it works on Port-J, -K, and -L.
The reason is twofold, first, calling code of PulseOut() omits to set ... |

I am talking about simulation now. When some events trigger INT0 or INT1 program jumps to desired location do some code stuff.
The Bascom simulation is not the exact equivalent of the µC's hardware.

programming through the bootloader. Not sure if that makes a difference.
The bootloader can't access fuses.
That's why programming via BL is safe, while with ISP you can mess things up. |

They are stored in order. If you want to keep EEProm mapping, you need to add new ERam-variables to the end.
Be careful not to write in a loop, as this finally would kill the EEProm cells, also set t ... |

Configuration for DMA as well for DAC is reusable, you can issue more than one config, at one you enable, at the other disable it.
