NRF24L01 is one of the legal RF communicators for modern applications. NRF24L01 is the cheapest one and it comes with great features. A single module communicates at 2.4 GHz frequency which makes it legal. It can transmit and receive data by a...
READ MOREIn the previous guide (here), we took a look at GPIO output using STM32L053, now we shall see how to develop GPIO input driver. In this guide, we shall cover the following: Input modes. Develop the GPIO input driver. Code to toggle the LED using...
READ MOREIn the previous guide (here), we took a look at the ADC in continuous mode with DMA. In that guide, we used the ADC to trigger freely. In this guide, we shall use timer to trigger the adc to convert the channel(s). In this guide, we shall cover...
READ MOREIn the previous guide, we took a look at the internal DAC of STM32F4 (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 investigate why there is BSRR (Bit Set Reset Register) in STM32 to set/reset a specific GPIO pin. In this guide, we shall cover the following: Toggle pin with ODR and BSRR Reason behind BSRR 1. Toggle pin with ODR and...
READ MOREIn this new getting started with STM32L0, we shall use STM32L053 Nucleo-64 and blink onboard LED using only registers and develop the firmware from scratch without using Hardware Abstraction Layer or Low Level (LL). In this guide, we shall cover...
READ MOREIn this guide, we shall use STM32 to acquire data from BMP180 temperature and pressure sensor and display the results on OLED display. In this guide, we shall cover the following: BMP180 Sensor. Connection with STM32. Code. Results. 1.1 BMP180...
READ MOREIn this guide, we shall see how to configure the timer to work as input capture mode. In this guide we shall cover the following: Input Capture Mode. Connection. Code. Results. 1. Input Capture Mode: As we’ve discussed in an earlier tutorial, the...
READ MOREIn this guide, we shall retargeting printf which part of stdio library to debug you code. For example, interrupt handler, variable to be displayed etc. In this guide, we shall cover the following: Serial Wire Output. Implementing header file...
READ MOREIn this guide, we shall interface STM32 with GLCD12864 using serial method. We shall display some texts, shapes and graphics. In the guide, we will cover the following: GLCD 12864. Interface with STM32. Code. Demo. 1. GLCD 12864: Ordinary LCDs...
READ MOREIn this guide, we shall take a look at the internal DAC of STM32F407 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 this guide, we shall take a look at MAX7219 8-Digit LED Display Drivers and how to use them with STM32. In this guide, we shall cover the following: MAX7219 Connection with STM32 Code Demo 1.1 MAX7219: Unlike the 74HC595 shift register, we...
