Hi,

I've got a huge C++ class. When I compile it, the following error message occurs:
error: class is too large
I would like to know what this does exactly mean. Code too large, data too large ?
What are the means to tackle this issue? I already…

This code has worked for years in C51:

hello everyone: I have a question.

I have an const array ,and its length is 142 words(284 bytes).I locate the array to the adress 0xC1F000,and I will write the on-chip flash to renew the array in my appliance.

But I found that the XC167CI can only…

Hello!

The board is built on C167CS crystal, with external RAM and flash at two separate (with individual /CS) 16-bit non-multiplexed buses. The flash is split into two 8-bit-data chips, the WRCFG is set to have normal configuration of /WR and /BHE…

Hello,

I use the RENAMECLASS-command to define a BOOT_CODE-class.

When I create the following classes:

ICODE (0xC00200-0xC002ff), BOOT_CODE (0xC00300-0xC017FF)..

..and I force the linker to set the startup-code to:

Hi

I have been learning how to upload and download with the use of minimon xc16x tool.

So far I have managed to upload the software by using the command:

_connect
_clearselections
_addselection c00000,c05E10
_upload
_save test1.hex

From C00000…

I'm getting Class B Illegal word operand access trap on a C161 board and I don't know why. The problem is reproducable, but moves unpredicatably as I modify the code. My trap handler spits out the top three stack entries, but they don't look credible…

Hallo, All!

These days I have migrated to newer Keil IDE version and found my older C++ project can not be compiled anymore. The IDE is installed and licenced correctly. If I return back to older version, everything is being compiled just perfectly…

Hi all,
I found a related Topic on uV2 (http://www.keil.com/forum/docs/thread9355.asp). Unfortunally no practicable solution can be found there.

Is there any Registry Switch etc. on uV3/WinXP?

Best Regards,

Hello All,

I have a short question, since got confused with "User's Manual, V2.0, Jul-2000, CS167CS Derivatives".

I have to use either P3.6 or P3.7 as general purpose external interrupt input. As per pin T2IN, the manual clearly stated…

I'm writing a library to set a Port BIT , that can be used on ARTX for xc167 . I use a function with parameters "PortAddr" and "PortBit" :

*(PortAddr) |= ( 1<<PortBit );

and analog function for Clear the bit .
This function…

Hi all,

This problem has been on hold for a while but a collegue of mine is looking at it again:
Our app is running from flash but we want to run it from RAM (in case we would have performance issues). RAM has less wait states. What we see on the scope…

Feature request:
Our Keil C166 compiler does not make a distinction between standard output or standard error. It would be nice if error/warning messages would be displayed on standard error. This make it easier to redirect output, handle logging in…

Hi all,

The C167 has edge based external interrupts (programmable to rising/falling/both). Does anybody have a reference to info on how to interface it with a level based interrupt device (e.g. an external multi-port UART)? When you OR several interrupt…

Hello! I use XC167CI and wrote bootloader described in C166: SHARE INTERRUPT VECTOR WITH BOOT LOADER http://www.keil.com/support/docs/2881.htm

Hi,
I've got a problem with strtod() from the stdlib and I still don't get it. I cannot find the mistake.

Using the example from the online-help

  float f;
  char s [] = "1.23 other";
  char *p;

  f = strtod (s,…

Hi all,

Situation:
Our code was running from flash, data was stored in RAM. Because of a faster processor we're going to get, we changed the startup so code gets copied to RAM and everything is running from RAM.

We also have a PEC transfer for…

Hi all,

Our app tests the watchdog by not servicing the watchdog but also setting a magic flag in RAM to see if the reset was caused by the test or for real.

I made a small test app to test watchdog behaviour and when I enter a while(1); I do get a…

Hi all,

We're using a rather old development kit (3.x) for our project.

1) Our current map-files do not give a summary of the total code/data size unfortunatly. Does the new linker (6.x?) produce more map-file output, including this info? It would…

Hi all,

Is it possible to print bit types using:
