Than you for replay
i try using pickité for the display bord but the other pic have a short circuit in vcc and gnd
AND FOR THE DESIGN QUESTION it is not my design cause i m trying to repair the equipement
hi all
there is a small machine that work with two pic's and they have communication between these two pic's
communication like
the 57a with 7 segment display and button i already do the prog for those componant
and the 72a phase control and reading tacho for speed
so the type of...
hii evry body can any one help me please i found this in a board that recive 4 20ma from a thermo regulator and get readed by the adc of 16f877
my poblem is about this schematic i confused about comparator or current to voltage converter
so please help
thank you for the replay
i alredy have this idea about the circuit
and i found it in a board with pic microcontroller and my project is about to replace this board by a new one
i just asked to undrestand how the conceptor of this bord work and i add that at the and of the AOP
there is a...
hello every one
i m trying to understand a small circuit for interfacing 4-20ma to a pic
i think after this circuit i must calculate the adc inverse that means for 4ma i wil have around 4.44v
and for 20ma i will have around 0.88v is that true
and is the amplifier here work as a comparator...
thank s freind
i m working with ccs compiler 4.110
"This will give you a counter for each valve that can hold 0 - 255 (0s to 2.55 seconds) that automatically counts down to zero then stops. When the value is above zero the valve turns on, when it reaches zero it turns off. By loading the...
hello evrybody help please
i have to make a commande in 15 valves
im using pic 18f452 at 20mhz
the fact is the way of opning this valves (i mean in programmation not pratique )
the problem is
each valve have a variable opning time from 0 to 9 like this
0= 0.00s
1=0.10s
2=0.14s
3=0.20s...
thank you for your help
For now i got it work for tow MCP's but....
working with portA for tow MCP okay
working with portB for the tow mcp not working ISIS give me an error about MCP23X17.dll
and i make a debug and it seems all okay the register abd the data sent
excuse me but i m...
Yes i allredy tried to write a code to change the outputs but it does t work i think i must set the register before but when i test it in isis simulation shows the register without modification
hi every one
i m blocked about this mcp23s17 and spi fonnction
i would programm a 18f452 with ccs compiler i already try the ccs driver for mcp 23s17 but in isis i see the command in the spi debugger but nothing change in the mcp register or the mcp outputs
thank's in advance
MCP driver...
Hello everyone
excuse me for my english
so i m trying to make a board that read the output signal from an ascon x3 controller so i just need how can i make the relation betwen the ma output and the tempreture
is my idea true
this is my idea
for 4 ma ---------> 0 °C
20 ma -------->...
hello bmb_10 yes it is alredy compiled and it give me the signal in the picture of my first post
i use ccs 4.057
thank you for all i will try logic operators && and tell you
