I have a 4 wire stepper motor. What type of Timings need to rotate stepwise? I want to turn the motor at different speeds. Is this ok? Or is this High pulse (mark time) is too much for each periods?
I'm feeding this 5V microcontroller pulse to the TB6600 stepper motor driver.
Thanks for the suggestions. Sorry for the late reply. I was busy with this design.
I want to know below timing before I proceed with the SPI routine with SD card..!!
Oscillator = 16Mhz Internal

Hi Mike Nice to see you.
I use HXD Hex Editor, Below shows the binary file which generated from another software.
I open the HXD Hex Editor & open the above binary file. I can see like below (24 bytes). From this "HXD Hex Editor" I'm going to write to SD card as raw. There is no any file...
Hi,
I have a SD card with raw data (Binary data).Can I use standard SPI with a low RAM PIC16F series chip & read the 8bits values & show in UART? Without using high end PIC18F with FAT file systems library etcc..!!
*PIC16F1509
*SD card 8GB
*Both will supply from 3V3.
Thanks
I have a normally close signal from a break glass. I want to make a relay active when it opens (breaks).
Is my diagram ok? I also need a break glass status output from the same relay on its other pole. That is why I used a relay.
Relay load is more than 10A DC.
The PFC8574 bare chip is 8bit wide.But I'm using I2C LCD module.Which can be connected to a LCD using 4bit method.
In 4 bit mode I'm struggling how to achieve Enable pulse in two nibbles?
Hi,
I'm stuck on a program. That I'm driving a 16X2 LCD from a PIC12F675 via a PCF8574 I2C module.
I'm confused on how to write the LCD Enable Line make transition from Low TO High state on each nibble in 4 bit mode?

This is a domestic type modern panel. So it must be in a slim box so it can mount on a living area. Sealed Lead acid type batteries are too big & needs bulky enclosures :(
I have made a wireless security alarm. It uses PIC microcontroller & RF433 module to receive signals from remotes. Also it has SIM800L GSM module. The entire circuit is powered from 5V supply. But it has a siren out that is 12V.So I power it from a 12V DC wallwart.
I'm struggling to select a...
I have wired 12 MAX485 chips as in the diagram.Each MAX chip has its own microcontroller connected that I have not shown here.The 12 max chips placed closed by within 6 inches distance each other.The RS485 data comes from 1 Meter distance from a nearby panel. I used CAT5E cables.
Want to...
Some more doubts refering my below schematic...!!
1)How is the polarity of my input capacitor ?
2)Do I need the C2 capaciotor?
3)Do I also need that output 100R resistor?
