I was thinking of passing on PIC16F785 which is updated to PIC16F1709. PIC16F1508 is also something that looks possible. Unfortunately the price is a problem for me. The PicKit3 is not available anymo ... |

Thanks to everyone for the replies, It will take me some time to go through this, also I have to work.
My purpose is to build a first stage SIM MCU system which only sends SMSs and then to upgrade ... |

Sorry for the double post. I tried, but it did not work for me. Its strange, because on a hand soldered universal PCB the MCU works correctly, and the ICSPDAT and ICSPCLK pins are not connected to any ... |

Currently I have pullup resistors on ICSPCLK and ICSPDAT which I need for the keypad to work. I will try adding a pulldown resistor and see what will happen. The whole prototype will have to be rework ... |

I use PicKit2 v2.61 to upload the hex file. It has an option to start the MCLR and VDD pins.
Compiler CCS PIC C v5.82.

It works when I use the programmer PicKit. How does the programmer pull the MCLR pin high? What is the difference between the programmer and a pull-up resistor? |

@temtronic
I did not know that the clock frequency changes with the voltage, I am using 4MHz, I hope the lower voltage has no impact on this.

About command mode, to summarize:

I will describe the steps below:
1. Create and compile the code with the CCS PIC C compiler.
2. Use PicKit2 or PicKit3 programmer to upload the hex file to the chip.
3. The pull-up resistor is 2k ... |

Hi,
To everyone who helped me so far, thank you very much!
I created a prototype, it includes an LCD, PIC16F690 and a keypad. I am unable to disable the MCLR pin through software, but when I tur ... |

Thanks,
I already know how to use fprintf ().
Example:
#USE RS232(UART1,ERRORS,BAUD=9600,STREAM=COM_A)
fprintf(COM_A,"Online\n\r"); |

The paired device appears as a logical 'serial port' device on the
phone. Data srriving on this goes into a software buffer, and if nothing
reads this it eventually will be lost.

So I have to know what the app uses or if I am using 2 modules to define this by myself.
And how does the pairing part work? |
