Arduino has a built-in SPI library and hardware to communicate with SPI devices. In this circuit, we will connect 2 SPI devices to an arduino microcontroller. We will show how this is actually hardwared together. The 2 SPI devices will be 2 4131 digital potentiometers. We will wire these ...
PID Loop Frequency– a.k.a. looptime, is how fast PID calculation is run. The maximum value depends on how powerful your FC processor is, generally speaking, F4 can run up to 4KHz while F7/H7 can run up to 8KHz. It also depends on the Gyro update rate, if you have the BMI270 ...
Differences between SPI and Arduino shiftIn SPI is fast. SPI operates only from specific pins. SPI accommodates different clock types e.g. normally high etc. SPI transmits and receives data at the same time. shiftIn is slow. shiftIn can only receive data. shiftIn can work from any ...
The brain of this robot platform is an Arduino Mega board which controls each wheel individually. Each wheel is attached on a NEMA 17 stepper motor, and knowing the fact thatstepper motors can be precisely controlled, I added one more cool feature in the app through which we can program the...
Placing and wiring is very intuitive and with tens of thousands of components to simulate, curiosity and creativity can be encouraged in equal measure. Together with our world class mixed-mode SPICE simulation engine Proteus provides a safe, fast and immersive learning environment for students.The ...
In this post we will be learning how to interface Nokia 5110 display with arduino microcontroller and how to display some text, we will also be constructing a
I2C alternatively known as I2C or IIC is a synchronous master-slave communication protocol where a signal master device can control multiple number of slave devices over a single wire (SDA line). I2C combine the working of UART and SPI protocols for example SPI supports multiple slave devices co...

There are two types of communication between the gyro and processor: SPI and i2c. SPI is the preferred communication protocol between the IMU and processor because it allows for a much higher gyro refresh rate than I2C (which has a limit of 4KHz). Almost all modern FCs today use SPI conne...
Breadboards have huge stray capacitance and the SPI interface is fast – mixing the two would result in a circuit that is quite unstable if not outright faulty. Default arrangement ofMini shieldhas already been noted in “Board Layout” section. ...
