In this guide, we shall discuss how implement timeout for peripheral driver in polling mode. In this guide, we shall cover the following: Implementing time out. Example on I2C. 1. Implementing Time Out: In order to implement timeout in your...
READ MOREIn the previous guide (here), we took a look how to configure the SPI module on STM32F103 and successfully transmit data over the SPI bus. Now, we shall receive data from the SPI bus. In this guide, we shall cover the following: Receive data...
READ MOREIn the previous guide (here), we took a look at the feature of internal RTC of STM32F4. In this guide, we shall develop the driver to read/write from/to RTC. In this guide, we shall cover the following: Initializing the RTC. Update RTC. Read from...
READ MOREIn this guide, we shall see how the internal RTC of STM32F4 is working and what features it holds and in part2, we shall configure the RTC and display the time and date on Liquid Crystal Display (LCD). In this guide, we will cover the following...
READ MOREIn this article, we will took at the RFID and how it does work and use RC522 to read RFID tag and display the tag ID on I2C LCD. In this article, we will cover the following: What is RFID. RC522 RFID module. Connection with STM32. Code. Demo. 1...
READ MOREIn this guide, we shall discuss what is SPI and how transmit data over SPI. In this guide, we will cover the following: What is SPI. SPI pin setup. SPI initialize. SPI transmite function. Result. 1. What is SPI SPI, which stands for Serial...
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 this guide, we shall see how to configure the core of STM32F103 and make it to run at 72MHz which is the maximum core frequency for F103C8. In this guide, we shall cover the following: Getting the correct parameters from CubeMX. Setting the...
READ MOREIn the previous guide of PWM (here), we saw how to configure the timer to operate in PWM mode and update the duty cycle using for loop. In this guide, we shall use DMA and set of predefined duty cycle to update two channels of PWM. In this guide...
READ MOREIn the previous guide (here), we saw how to read three different register from a slave device (DS3231 RTC) and display the time stored in the RTC. In this guide, we shall see how to write multiple bytes. In this guide, we shall cover the...
READ MOREIn the pervious guid (here), we took a look how to write/read single byte using I2C and the slave device is DS3231 In this guide, we shall see how to read multiple byte of DS3231 which they are seconds, minutes and hours and display them on the...
READ MOREIn the previous guide (here), we took a look how to write a single byte with memory address to a slave device (DS3231) and successfully wrote a byte to the seconds part of the RTC. In this guide, we shall combine the write function with read...
