Hi Milan,

I did not tried to compile your code, but when you write

data[0] = T;

your "T" is undefined.

P.S. you should use the "Code" button when you post source code in your message.

Hi,

You just have to use the standart C function: int atoi(char *s). In the Help file, go to "mikroC PRO for PIC Libraries" -> "Standard ANSI C Libraries" -> "ANSI C Stdlib Library" for more information.

Good luck

Marc

Hi Franek, Sorry for the late response, I've been on vacation last 2 weeks. I'm glad that your bootloader works fine. You are right when you say that the bootloader doesn't modify the configuration bits. I have programed this bootloader to be used as a "firmware upgrader" for my products, i.e. I mak...

Hi Ben and grandegiove, This is what you have to do: If you change the compiler's version, or if you change something it the bootloader code you will have to: 1) compile the bootloader until it fits in memory 2) modify the bootloader code (I'll explain this) 3) re-compile the bootloader 4) burn the ...

Hi,

Does pin 3 of your DS1307 (VBAT) is connected to a battery or to the same 5V that powers your circuit? If it's not a battery, your DS1307 won't be able to keep time when your circuit isn't powered, and it will reset to 0.

In fact, the biggest problem I see with a bootloader not located in the highest memory locations is that it cannot load any hex file. For that, the bootloader would have to decompile the hex code and then offset all the variables and constants references in the code: a nigthmare! In my bootloader, I...

The reason I chose to use a low end version is because I was unsure how to ensure that the compiler did not attempt to use the higher memory locations. If I could have told the compiler that memory above for example 0xD800 was not to be used then I would have been happy to compile my main code at t...

Hi everybody, Well it seems that we are starting to have a good choice of MMC bootloaders! David, you have an interesting approach. Your warning about the maximum size of the user program applies to my bootloader too. I should have indicated this. And you came to the same conclusion I found: we cann...

Hi,

Instead of a function, you can also place constant values in memory the following way:
You won't need the fake function call that way.

Marc

Go in this folder: C:\Program Files\Mikroelektronika\mikroC PRO for PIC\Examples\Other\Bootloader\ and choose between P16 and P18 depending on your PIC. The bootloader is there.

Have a nice day!

Marc

Hi Dave, I don't have much time now, as I'm in vacation and I will leave for camping in a few hours. When I'll be back next week, I will explain it in detail. All I can say (and it won't be good news for you), is that the SPI and MMC library functions used by the bootloader cannot be reused by your ...

Soon I will modify it to make a version without the LCD display - the bootloading status and progress being shown by a flashing led. That will be usefull for a project that doesn't use a display.

Hope that you'll find my bootloader usefull!

Marc

Homermike and M.Pathma:

I have finished my MMC bootloader for the PIC18F4620. You can obtain it here

Marc

Thank you p.erasmus and filip for your kind words, I appreciate, especially from you guys who are prolific contributors. I don't have any more time to work on it right now, but it would be great if other people that bootloader (smaller size, encryption,...)

Have a nice day,
Marc

Hi Massimo, I haven't tried it myself, but I don't think that you can use software SPI with the MMC library. As stated in the MikroC help about the Mmc_Init() function: "The appropriate hardware SPI module must be previously initialized." But you can shift the pins used by your GLCD: instead of usin...
