strange hd44780 behaviour
After power on the dispaly needs to be sent the commands to set it into 4 bit mode which I assume your code is doing but it may be that the display needs an additional delay after...

avr vs other uC
Absolutly unbelieveable arrogance displayed by Mr Smiley Micro et al,if anyone is any doubt about the 8052's design's influence on later processors then they only have to read the...

lcd rolling text help
If you are using a 44780 compatable display controller and you read the datasheet then you'll see that the controller can implement whats called a display shift for you in...

avr vs other uC
You get a fair share of beginners asking beginers questions on 8052.com as well.I didnt take arrogance at school sorry,I just think that if somebody is considering what processor...

avr vs other uC
It appears to be only you who wants to start a flame war,sorry to have to tell you this but the 8052 is alive and well and used in many products,with new variants being produced...

LCD problem
The answer is not to tie the lower 4 bits of the LCD interface to ground unless you are using a system which you sometimes see where the R/W is tied to ground and the code doesnt...

avr vs other uC
Nobody has mentioned using an 8052 or variant which i find slightly odd as it is still an industry standard and outperforms the AVR in certain respects such as bit manipulation,...

SPI problems
MOSI stands for Master Out Slave In. MISO stands for Master In Slave Out. so clearly you connect MOSI to MOSI and MISO to MISO the basic problem with SPI is its just a shift...

Easy to use RTOS for AVR
My main objection to an rtos on an 8 bit processor is that you are using software to do context switching and task scheduling, using up valuable resources, when you already have a...

multicore processing
The original poster doesnt really say what he is after but there are two distinct areas involved,safety critical systems and multiply redundant systems.They are both typicaly used...

Easy to use RTOS for AVR
Quote:RTOS's are nice in that the OS maintains state information for the programmer. So, instead of a complicated state machine for each task, running off an interrupt timer, the...

Easy to use RTOS for AVR
An 8 bit microprocessor is no place for a real time operating system,it simply does not have the resourses.The only reason you might want to try to use one is to learn how proper...
