Unable to simulate C8051F120 peripherals in keil uVision2

"Why do you call SFRs which we all know what is "peripherals" which I would consider things like a printer or LCD?"

In my experience, it is common to refer to the extra bits in a microcontroller - ie, the bits outside the CPU "core" - as "Peripherals" (often, "on-chip Peripherals").

In the particular case of 8051-derivatives, the CPU "core" gains access to the Peripherals via SFRs.

The Keil simulator does more than simply emulate read & write accesses to SFRs - it simulates the action of the actual "peripheral" behind the SFRs; eg, writing to SBUF will actually cause a character to be displayed on the serial window, or a charcter to be transmitted from the PC's COM: port, and the TI bit will be set.

Thus, I think it is reasonable to speak of "peripherals" rather than just "SFRs"

That's my 2p, anyhow!

"what is 'peripherals' which I would consider things like a printer or LCD?"

Well, the front page of the C8051F120 datasheet lists "Analog Peripherals" and "Digital Peripherals" in bold type in the features list...

In the particular case of 8051-derivatives, the CPU "core" gains access to the Peripherals via SFRs.
And, in my example so would a printer, not argument.

Ok, I'll rephrase, why call a display of SFRs peripherals. I do not see any "peripheral workings" displayed, just the SFRs.

Because it's not just a display of SFRs. It's actually a full-blown controller dialog of the thing in question.

Or because that'sabout the only term that fits all the things that go in there (external ports of all kinds, timers), and because there's only one such main menu entry --- splitting it up into several wouldn't particularly improve things.

"And, in my example so would a printer, not argument."

It wasn't supposed to be an argument - just a statement of where the SFRs (8051 term) fit between "peripherals" & the CPU "core"

"Because it's not just a display of SFRs. It's actually a full-blown controller dialog of the thing in question."

Absolutely: as in my example, the UART simulation is not just a display of SBUF, etc - it actually simulates the operation of the UART by sending & receiving characters, setting interrupts, etc.

Please provide an update as to when the simulation dll will be available. I am willing to test a beta drop if possible. Thanks.
