  • STM32F429I-DISC1

    Datasheet for stm32F429ZI https://www.st.com/en/microcontrollers-microprocessors/stm32f429zi.html This board have a 2.4 Resistive touch TFT LCD. which uses the ILI9341  controller. The touch screen which I got with this display is very bad. you have to press down on the screen before you power ON the device. The microcontroller is based on the ARM CORTEX M4F which can…

  • STM32F746IGT6 – An ARM CORTEX M7 Based Microcontroller

    Datasheet It’s an ARM Cortex M7 based microcontroller which has a maximum clock speed of 216Mhz. Well, it has a few peripherals which when combined with its CPU, makes it a very powerful controller. Those peripherals are LTDC, SDRAM Controller. It also has the usual set of peripherals from the ST. But these in particular…

  • How to redirect printf() to USART in STM32f103RB using STM32Cube IDE

    Printf() function can be redirected to USART and also towards SWO. Here you will see how to redirect printf() to USART in STM32f103RB You need to rewrite this code in your main.c file If you have created your project using STM32CubeMX or STM32 Cube IDE, then you can rewrite it in between USER CODE BEGIN…

  • How to make ATmega GPIO work as Input or Output

    AVR Input Output Port programming means you have to program its GPIO pins. GPIO – General Purpose Input and Output The GPIO is a very important peripheral of the microcontroller. Using the GPIO we can use the same exact pin for Input or Output. To make the PIN input or output we need to set…

  • Analog Modulation based Transmitter using ATmega16a

    Analog Modulation is the very basic form of modulation that can be produced using very basic components. The ATmega16a is used to generate a square wave. The frequency can be generated by carefully adjusting the 8-bit PWM Timer. Using the above method a Carrier Signal is generated. You can hear the carrier pulses on AM…

  • Memory Space in ATmega16A

    To effectively program AVR based microcontroller you must have knowledge about its memory space. Since there is not just one memory space. There are three different address spaces. They are: Data memory (SRAM) Here all your the intermediate results are stored and all the run time calculation get carried in this memory space. Program memoryIt…

  • Arm Based Microcontrollers

    At the time of writing this article ARM-based microcontroller means the microcontroller which uses a 32-bit RISC processor design from ARM holdings. Presently ARM Cortex-M series of processor cores are being integrated into microcontrollers. The ARM-Cortex M family comprises the following processors. Cortex-M0 Cortex-M0+ Cortex-M1 Cortex-M3 Cortex-M4 Cortex-M7 Cortex-M23 Cortex-M33 Cortex-M35P Cortex-M55 The Cortex-M4 /…
