In 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...
READ MOREIn the previous guide (here), we took a look how to configure the ADC to use DMA with multiple channel. In this guide, we shall use timer to trigger the ADC each 2 second and display the result on serial terminal. In this guide, we shall cover...
READ MOREIn the previous guide (here), we took a look at single channel continuous conversion interrupt driven ADC configuration. In this guide, we shall see how to configure the ADC to work in multiple channel with DMA. In this guide, we shall cover the...
READ MOREIn the previous guide (here), we took a look at how t configure the ADC of STM32L053 in single channel single conversion mode. In this guide, we shall see how to configure the ADC to work in continuous mode. In this guide, we shall cover the...
READ MOREIn this guide, we shall learn how to use the ADC of the STM32 for single channel Single Conversion mode using only registers. The ADC is commonly used to measure the voltage from a sensor for example temperature sensor such as LM35 which can...
READ MOREIn pervious guides(here), we took look how to receive 5 characters from DMA and echo back the sent characters. However, the limitation is to need the number of received character in advanced which will limit the capability of the firmware...
