Hi
You don't change it, Mark, it's a HW thing.It comes from the log AND register of the UART
I will try to find the schematic that was sent to me by Atmel once,there you can see why PIND is set.

Ok
I thought you were serious. I misunderstood "sure?" as your sarcastic remark.
I apologize for the misunderstanding.
The questioner asked, I answered. Nothing more nothing less. Just because you ... |

Hello MWS
Looks like it.
The following instructions will be carried out
LDI R24,0x18
STS 0x00C1,R24
Or write the bits for RXEN0 and TXEN0. Since the other settings are done before that, the UART ... |

Hi
disconnect PD1 from external circuits and try again. If it behaves the same way it will be time to reach into the drawer for a new chip.
I'm also wondering do you by any chance have an arduino bo ... |

Hi
Check out the EM 4305 circuit, it's cheap and programmable. It works at your desired 125kHz. It is also sold as a sticker or card. The reading distance is 6cm,but with a good reader you can go fur ... |

Ok
the electronics are in the trolley, if I understand correctly.
From this perspective, the sensors must be passive without power.
What about trying to use programmable RFID? Wouldn't that be a so ... |

I personally would take a hall sensor, permanent magnet and some small attiny in this environment. Something from the new range seems optimal in terms of speed.

Hi
I would use something like the JRT M88 for about $50.
But we have little information about the environment where it will be measured and the accuracy. There is also the question of whether the ro ... |

Hi
how fast will the cart move?
If it is not ensured that the trolley is in the reading position for at least 1s I would think about another solution.
If there is a given time then you have plenty ... |

Hi
In that case, disconnect pins 27 and 28 of the processor from the PCB (heat and lift with tweezers) and connect RxD and TxD directly.
You don't need any expensive equipment to do this.

I knew there was another company that makes "clones" of the 8051.
Coincidentally I have now been commissioned to test one product and there is an IO N76E003AT20 used. Which is an alternative (alm ... |

Hi Mark
No problem, I know how it is from the microchip sample.
I have these circuits because they are used in on-grid inverters.
There will be a 64kB series next month. PDIP is a future product fo ... |
