In the previous guide (here), we took a look how to configure the UART to receive a character using interrupt and echo back the received character. In this guide, we shall use DMA to transmit data. In this guide, we shall cover the following...
READ MOREIn the previous guide (here), we took a look at how to receive a character using polling mode. In this guide, we shall use interrupt to receive the data. In this guide, we shall cover the following: Enable RX in interrupt mode. Interrupt handler...
READ MOREIn the previous guide of timer (here), we took a look at timer interrupt. In this guide, we shall see how to setup timer in PWM mode to fade an LED. In this guide, we shall cover the following: What is PWM. Configure the timer and GPIO to...
READ MOREIn the previous guide (here), we took a look how to configure the UART to transmit single character. In this guide, we shall use UART to receive a character and echo the received character. In this guide, we shall cover the following: Configure...
READ MOREIn this guide, we shall use UART in TX mode to send single character each time. In this cover, we will cover the following: UART. Configuring pins to work in UART mode. Configure the UART. Send character. Code. Results. 1. UART: To transfer data...
READ MOREIn this guide, we shall interface HK1100C pressure sensor with STM32 and able to measure the pressure from 0 up to 1.2MPa. In this guide, we shall cover the following: HK1100C pressure sensor. Connection with STM32F4. Getting the relative...
READ MOREIn the previous guide (here), we took a look how to configure TIM2 of STM32F103 to generate precise delay from 1 milliseconds up to 65 seconds. In this guide, we shall use timer interrupt to generate interrupt each second and toggle the LED...
READ MOREIn the previous guide here, we took a look how to configure a pin as output and blink an LED. In that guide, we used crude delay of for loop to blink the LED. In this guide, we shall use timer to create precise delay ranging from 1 millisecond...
READ MOREIn this guide, we shall use MCP4131 digital potentiometer with STM32 to vary the potentiometer using software. In this guide, we shall cover the following: MCP4131. MCP4131 connection with STM32F4 SPI Code. MCP4131 Code. Code. Demo. 1. MCP4131: A...
READ MOREIn the previous guide (here), we saw how to configure a GPIO pin as output. In this guide, we shall configure another pin an input to read from push button. In this guide, will cover the following: Input modes. Develop GPIO Input driver. LED...
READ MOREIn this new guide series, we shall develop some drivers for the most widely used STM32 which STM32F103 aka bluepill. In this guide, we shall cover the following: Setting up the environment Getting the required documents. Developing GPIO output...
READ MOREIn this guide, we shall use STM32 to develop a driver to set and get the time store in the DS3231. In this guide, we shall cover the following: DS3231 Module. Connection with STM32F411 Nucleo-64. Developing the header file. Developing the source...
