In 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...
READ MOREIn the previous guide (here), we took a look how to configure the UART of STM32L051 in transmit mode. Now we shall see how to configure the UART to receive data and echo back the received data (Transmit receive mode). In this guide, we shall...
READ MOREIn this guide, we shall see how to configure I2C in STM32F7 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. Code. Demo. 1. I2C write mode: In...
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...
