In the previous guide (here), we saw how to configure the I2C in STM32L053 to write to slave address using DMA. Now, we shall read from a slave device using DMA. In this guide, we shall cover the following: DMA initializing. I2C Read using DMA...
READ MOREIn the previous guide(here) we saw how to configure the I2C to write to a slave device, n 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) using DMA. In this guide...
READ MOREThis guide shows how to interface the STM32F4 board with ST7789 TFT display.The ST7789 TFT module contains a display controller with the same name: ST7789. It’s a color display that uses SPI interface protocol and requires 3, 4 or 5 control pins...
READ MOREIn the previous guide (here), we took a look at I2C read mode to read set of registers from DS3231 RTC module using DMA mode. In this guide, we shall use DMA to write those register. In this guide, we shall cover the following: I2C configuration...
READ MOREIn the previous guide (here), we took a look at I2C read mode to read set of registers from DS3231 RTC module using polling mode. In this guide, we shall use DMA to read those register. In this guide, we shall cover the following: I2C...
READ MOREIn the previous guide, we took a look at the internal DAC of STM32L053 (here) and we where are able to generate sawtooth using DAC and software trigger. In this guide, we shall use timer and DMA to generate sinewave using DAC. In this guide, we...
READ MOREIn this guide, we shall take a look at the internal DAC of STM32L053 and develop software triggered DAC to generate triangle wave. In this guide, we shall cover the following: What is DAC Configure DAC Generate wave form from DAC Results 1 What...
READ MOREIn the previous guide (here), we saw how to configure the UART in full duplex mode with DMA. However, the application need to know the number of transfer in advanced in order to receive data. Using IDLE line, the application doesn’t need to...
READ MOREIn the previous guide (here), we saw how to configure the UART and DMA to work in transmit mode. In this guide, we shall see how to configure the DMA and UART to work in full duplex. In this guide, we shall cover the following: Configure UART in...
READ MOREIn the pervious guide (here), we took a look at how to receive the data in polling mode, in this guide, we shall see how to transmit the data over UART using DMA mode. In this guide, we shall cover the following: In this guide, we will cover the...
READ MOREIn this guide, we shall see how to push STM32L053 to run at 32MHz rather than the default frequency of 2.096 MHz. 1. Steps: In order to push STM32L053 to maximum, we shall use external oscillator. Since the Nucleo-L053 has built-in 8Mhz generated...
READ MOREIn the previous guide (here), we took a look how to use ADC in DMA mode to acquire the data from two channels. In this guide, we shall see how to configure the ADC to be triggered by timer. In this guide, we shall cove the following: Timer...
