  1. Re: Read state of specific bit (i.ex. of a PORT)

    Thanks Richard :wink:

    Nevertheless, I still don't get it.

    Is this statment (version 2013-03-06) really correct?
  2. Read state of specific bit (i.ex. of a PORT)

    Hi There,

    I'm "reading" a 3x4 keypad matrix and want to show the user he is currently pressing a button.

    So I light up a LED while any key is pressed and shut if OFF when the key is released...

    Bootloader from MicroCode Studio

    What do you mean exactly if I may ask? Is customizing such a file overwhelming?

    But if one has the need of a system that must be "updateable" without a programmer, what would be the alternative?

    Re: 8-bit Bootloader from Microchip

    Since I own MCSP (I forgot the included bootloader....:rolleyes:), I give it a try.

    I'm using a PIC18F2431 and here is my blinky:

    Thanks pedja089,

    I have effectively started this way ;-)
  8. How to trap incoming Calls/SMS when no RING pin is available

    Hi All,

    As I'm playing with different GSM modules, I'm stumbling on SIM5320E and SIM5360E that have no easily accessible "RING" pin (like on SIM800/SIM900/etc modules) which I normally use to trap...
  9. Re: Testing a GSM module via Mecanique's Serial Communicator - "terminator" issue?

    Thank you Ioannis.

    I'm awaiting a SIM5360EVB and I will try again if the LF or CR makes the difference.

  13. 2G, 3G and 4G - how do I determine what my module is capable of?

    For my latest project, I'm using a SIM800L GSM module.

    But what is telling me what networks (2G...4G) it is really capable of?

    The module's datasheet isnt' clear enought to me so I have doubts...

    Hi All,

    I've heard about bootloaders for the last 14 years but never tried myself because I didn't have really the need for it.
