ir receiver photodiode circuits
Hi everybody,
sorry to dig up this thread, but there is circuits using a photodiode output as voltage input for an analog comparator without adding an opamp as converter (fig 2 in the linked file)...
l298 l297
hi,
i'm designing the same schematic,
I read in the datasheet that the CONTROL pin of the L297 should be connected to VCC if we need to activate A,B,C,D outputs and GND for /INH1 and /INH2, does this mean that :
if we have an unipolar stepper motor----> connect CONTROL to GND...
understanding an isis netlist
Hi everyone,
I have made a circuit using ISIS 7.1 and now I would like to design the Circuit PCB with Eagle Cadsoft (I have the 4.01 version), I found in ISIS that it is possible to compile the netlist in different formats (Multiwire,spice,tango,SDF,...), so...
portb ccs
hi Saeed_pk,
My PIC is a 16F876,
if you don't mind, what's the difference between them ?
now only one interruption comes from RB6 and is generated by a push-button, (just to test the code) but then I'll have to manage at least 3 other interruptions inputs in the other pins.
I...
int_rb ccs
Hello all,
My code which consists on lightening a LED connected to RA3 with a push-button connected to RB6 was compiled with success (0 error , 2 warnings of conditions always true and false) but did no function when I tried to simulate it with ISIS however it was a simple one (see...
delay function using pic18f1320
hi Iain,
sorry for this tardiness,
you're right, that was the cause.
thank you.
Hi Kabanga,
I defined my delay function before the main() (see my code above)
mpasm 18f452 fuses config
hi Gorkin,
thank you for answering
sorry you're right, I should have mentionned my compiler, it's C18 from Microship !!!
does this change something ?
18f4525
Hi everybody,
I compiled a very simple C code ( written for the PIC 18F452) and I simulated it with MPLAB SIM in a PIC18F4525 , strangely, i found complete diffenerent outputs:
0x40 (0b01000000) insted of 0x5A (0b01011010) .
0x20 (0b00100000) insted of 0x3A (0b00111010) .
did the...
pic18f delay
Hi all,
I'm a begginer in PIC18F programming (I started yesterday ), I'm using Microchip C18 compiler in MPLAB, I compiled some simple programms that I found in the C18 getting started from Microchip web site https://ww1.microchip.com/downloads/e...ed_5129 5f.pdf
like this...
pic18f2550 + software isis
hi,
me I couldn't even be able to simulate the PIC18F452 and PIC18F4525 in ISIS with codes compiled with C18 of Microchip in MPLAB.
i'm using very easy programms from C18 getting started guide http://www.kevin.org/frc/C18_3.0_getting_started.pdf
help me...
.lib proteus memory nand
I'd like to know where can I download components that are missed in my Proteus ISIS Library (parallel flash memory ) ?
thanks in advance.
nand flash pic18f
hi,
yes they are different,
I have to write a low-level C programm to make the PIC able to Write and read from the parallel flash memory.
connection between the NAND Samsung memory flash and ATJ2085 (the other processor that share the Memory with the PIC18F) ...
flash memory pic18f
hi,
I discovered that MMC and SD card are also NAND type memory, does this mean that there will not be differences in the PIC program ?? :|
can anybody help me ?
