Re: [Sdcc-user] Newbie: sdcc for Atmel AT89c55wd
It should be even simpler: #define light P2_0 When you write just use: light = val; -- Ori Idan On 2/22/07, Raphael Neider <[EMAIL PROTECTED]> wrote: Hi, > 2. sbit light = P2_0 (instead of P2^0 for keil) This line creates a new sbit variable, initialized with P2_0, you probably want something like sbit __at(P2_0) light; I am no mcs51 expert, but this is a common error. Maybe you need to use __at(&P2_0), but I am not so sure. HTH, Raphael - Take Surveys. Earn Cash.

Re: [Sdcc-user] Some sdcc warnings
When a variable is marked as volatile (SFR are volatile by definition) the compiler will never optimize by assuming a given value for this variable. -- Ori Idan On 3/22/07, Raphael Neider <[EMAIL PROTECTED]> wrote: Hi, > TR0 = 0;// reset the timer > while( TR0 == 0 ); // wait for the flag to be set. > i++; // get out of the loop and increment > } > What is SDCC going to do in this case. > Will it say that line corr. to "i++" as unreachable code. > But how does the compiler know that? > If TR0 is not marked as `volatile' and does not refer to an SFR, SDCC will believe that TR0 cannot be modified behind its back and thus assume the loop to never be left: TR0 is 0 on entry to the loop, not changed within, thus TR0 stays 0 forever.

Re: [Sdcc-user] internal ram usage.... 8051
No, there are only 256 bytes. The upper 128 when accessed as direct access are the SFR's (Port, Peripheral Registers, etc.) When accessed in indirect mode you get the RAM. SDCC knows how to access it depending on what you use (Register or variable). -- Ori Idan On Nov 12, 2007 8:22 AM, Ulhas Vaidya <[EMAIL PROTECTED]> wrote: > hi, > > I request help regarding usage of internal ram.

[Sdcc-user] [OT] Programming P89LPC930 under Linux

Re: [Sdcc-user] documentation & open source generally
I also would prefer to develop without any IDE, IDE makes me feel chained. As for speed of development, most of the time spent editing the code anyway so I would use a good editor, that's all. As for documentation, this is a whole separate issue. We do need the best documentation we can use. But, remember SDCC is a free software so if one would like a better documentation, one should consider contributing to the existing documentation and not wait for someone else to do the job, since nobody will. -- Ori Idan On Tue, Sep 2, 2008 at 7:43 PM, Dave McGuire <[EMAIL PROTECTED]> wrote: > On Sep 2, 2008, at 11:40 AM, Bobby Garner wrote: > > A "great many" implies no more than an indefinite but significant > > number, and certainly not a majority.
