In 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...
