I do not use the IDE Keil or SILabs or anyone else (the shortcomings are too many), so I would not know, but it sounds ridiculous that the IDE can not generate a .hex file directly.

Hi Erik, unlike the Keil IDE, the Silabs does not create any HEX file (to my knowledge). It just compiles, then when we connect the hardware, it gives option to download the HEX file to the hardware. It does not allow the user to save the HEX file,somewhere in the folder.

maybe you can use the SiLabs flash tools to read out the code memory and save it as a hex file.

Regards,

In Silabs IDE there is a check box the Project Menu, Target Build Configuration item, dialog box called "Generate hex file", with an edit box to file in the name of the command line tool that will get launched to do the job.

Hope that helps.

Hi Steve,
Thank you, so much. It works!
I get back my words that we can't create a HEX file from Silabs IDE. I apologize!

Thanks to everyone whoever tried to help me .

regards
Shyam.

There are two things being discussed in this thread.
1) How to convert compiled/linked OBJECT code into Intel HEX format.
2) How to convert already downloaded code in FLASH to HEX file on PC.

For 2) you need to use the IDE Tools menu and the Upload Memory to File. However you'll be disappointed because that function doesn't create a nicely formatted Intel HEX file. It's just a stream of ASCII codes corresponding to binary values from FLASH, with each code separated by CRLF. That format is not very useful. I think that is what Scotty was suggesting and what classics was referring to.

Too bad, maybe someday Silabs will improve this feature. By the way, you don't need a HEX file to download to FLASH, right? You can just use OMF output.
Good luck!

The hex file is in the root project directory. Im using the Silabs IDE and it generates it for me just fine !

SiLabs offer a utility (ASC2HEX_v1.1.zip) as an attachment file of this KB
This utility converts the IDE readout into HEX file.

andrei,
I get an error when trying do generate hex file like UNKNOWN OH51-CONTROL 'AND',
If you are using the Silabs IDE to generate HEX file (per above discussion using Target Build Configuration, Generate HEX file) then examine the Output window in the IDE for something like:
Generating hex file...
C:\Keil\C51\BIN\oh51.exe "C:\Projects\Test.OMF"

The text shown in your Output window will be the exact line that the IDE emits to the OH51.exe program to perform the HEX conversion. Perhaps the command line has an error in it involving the word "AND" (per your question).

HEX file is file format originally created by Intel and adopted by many. It displays the binary values of the program in ASCII form, appending record framing information (start of record, count, checksum, etc.)

The OMF file format information can be found here.
