ir receiver photodiode circuits
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)...
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
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...
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.
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...
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) .
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
pic18f2550 + software isis
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 https://www.kevin.org/frc/C18_3.0_getting_started.pdf
nand flash pic18f
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) ...
parallel flash memory
I'd like to write and read in a NAND type flash memory (k9f2G08U0M of SAMSUNG) using a PIC18F4525.
after some researches in internet, I found this application note from Microchip...
I would like to know how to connect my GSM module (SIM300) to my microcotroller (PIC 18F4525) ??. I have to command the GSM module so that it dial a number if an input of the PIC 18F4525 is activated, aslo the SIM300 should be able to activate a relay (in the outputs of the...
