Hello everybody,
I am implementing a simple rtos with just 4 primitives: Timing, messages, events and counting semaphores.
Tasks run when the kernel dispatches one of these primitives.
Timing handles the task delays and timeouts.
Messages passes a pointer from task to task by the use of a...
Re: How to write a firmware which can run on multiple hardwa
Hi,
The compiled binary will not run on different controller, but you can have configurable source code. Use #define, #ifdef/#endif (if you are using C)... to configure which section will or not be compiled.
Hello,
I need to add a spi eeprom to a board that has a LCD with no other free pins.
The lcd is in 4bit mode. I am thinking about some glue logic in RS/EN/RW/D7, D7 being the real eeprom CS, but only allowed to go low for certain RS/EN/RW.
D6,D5,D4 are SDO/SDI/CLK.
What do you think?
Thank you.
tinymenu c30
Tinymenu is very nice and works perfectly with C30.
For the CCS compiler I could only manage to write a state machine. It is big, ugly but works.
Did anyone managed to write an efficient menu system for CCS?
eagle dspic33
Hi, I am looking for libraries of the latest microchip´s dspic33.
As I am starting with eagle, I don´t want to risk using one made by myself.
Thank you.
txt in microcontroller
This is not an easy task, maybe a year worth of study will get the job done.
You dont seem to know much about electronics. I think it would be better if you start reading about the FAT format. There are some entries at wikipedia's website.
Then you can get some mmc...
Re: Time to saturate a coil.
And what about if it was a linear system?
Like a relay or something with a fixed core.
Just thinking about the relation between different drive voltages.
Time to saturate a coil.
Hi,
I am looking for theories about coils and how they behave when it saturates.
Ex: A selenoid takes 10mS to open when 12v is applied, how long it will take to open if we apply 8v?
Thank you.
Re: Avoiding overflows in C
Hi,
I will use the "asm" way..
temp=sample0-sample1; //
if(STATUSbits.N) temp=0; //
temp=sample0+temp; //
if(STATUSbits.C)...
