Uploading hex code is specific to the 8051 derivative you are using.For example some microcontrollers like P89V51 and Nuvoton W78E05D have build in boot loader which can upload hex code through their serial port.

I've been doing a project about home automation in which I have to use timer interrupts with 8051 microcontroller. I've constructed the following code, however I couldn't manage to get interrupt working. It seems that the program does not go into timer ISR at all. I use a buton to simulate PIR input, therefore lampControl is triggered, no worries there. I use as a library.

I'm very interested in learning how to program using the assemblylanguage of the 8051, I think it will be a good grounding for me tobeing learning more complex topics... but I know nothing at themoment!

Just my opinion: you should start programming MCUs in C. If youstart doing it in assembly language, you'll make transition to C moredifficult for yourself. More than 90% of MCU programming should bedone in C. Knowing assembly language helps, no doubt, but you canlearn it by looking at the disassembler output for compiler-generatedcode.

Since the 8051 CPU has some quirks that make it a poor target for Ccode, I suggest that you pick a different CPU. Some people say thatAVR is good for beginners.

with the '51 understanding the chip is very important

www.8052.com/.../120112- includes links to the so-called "bible" for the 8051

"the bible" gives you the HW info you need and there is no betterinstruction set manual than "the bible" chapter2

Don't know. I didn't create the problem in any different manner,it was just a straight hex file that uVision had compiled, and then Iclick 'debug'. The code is for an MX device, but I don't have an MXsimulation yet (ic design sim of an MX cpu netlist) but I do have theplain 8051 sim, so I'm derating my sw to not use any MX extensions,which is awkward. I may have caused a problem in the manner that Ihad done this.
