In this guide, we shall see how to configure I2C in STM32L053 to write to a specific register of an I2C device (DS3231 in this case). In this guide, we will cover the following: I2C write mode. I2C write code. Demo. 1. I2C write mode: In order...
READ MOREIn this guide, we shall see how to configure I2C peripheral in STM32F7 to read certain amount of data from memory location. In this guide, we shall use DS3231 RTC to read seconds, minutes and hours. In this guide, we shall cover the following...
READ MOREIn this guide, we shall discuss what is SPI and how transmit single byte over SPI. In this guide, we will cover the following: What is SPI. SPI pin setup. SPI initialize. SPI transmite function. Result. 1. What is SPI SPI, which stands for Serial...
READ MOREIn the pervious guide(here), we took a look at the WS2812 and they work and type of communication required. In this guide, we shall see how to use PWM in DMA mode to control those LED. 4. Setting up the PWM and DMA: Since we shall use TIMER 1 of...
READ MOREIn this guide, we shall see how to interface addressable LED WS2812 with STM32. We shall see how the data should be send, and how to configure STM32 to communicate with these type of LED. In this part 1, we shall cover the following In this...
READ MOREIn the previous guide (here), the usage of Liquid Crystal Display with I2C is presented, in this guide, the usage of custom character capability of the LCD shall be discussed. The following will be covered: Custom Character of LCD. Code. Demo. 1...
READ MOREIn the previous guide (here), we took a look at how to implement the PID controller programmatically. In this guide, we shall use simple case study to control the speed of a DC motor. In this guide, we shall cover the following: What is speed...
READ MOREIn the previous guide (here), we took a look at the PWM mode in timer2 of STM32L053. In this guide, we shall take a look at the output compare where the the output will be toggled each time the timer overflow. In this guide we cover the...
READ MOREIn the previous guid (here), the timer interrupt was introduced with rate of 1Hz to blink the LED.In this guide, it shall present the usage of timer in PWM mode. This guide shall cover the following: What is PWM. Configure the timer and GPIO to...
READ MOREIn previous two guides, we discussed how to use timer to generate delay (here). In this guide, we shall look how to configure TIM2 to generate an interrupt every second and toggle an led every second. In this guide, we will cover the following...
READ MOREIn this guide, we shall investigate how to use timer to generate precise delay in down to microseconds ( will use 500 millisecond) delay here for demonstrations purposes only). In this guide, we will cover the following: What is the timer and how...
READ MOREIn the previous guide (here), we saw how to configure timer to work in encoder mode. In this guide, we shall take it step further and measure the rotational speed in RPM (Revolutions per Minutes). In this guide, we shall cover the following: How...
