In 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...
READ MOREIn the previous guide (here), we took a look at the i2c protocol and how to use the i2c to scan for the slave addresses. In this guide, we shall transmit data over i2c to slave device. In this guide, we shall cover the following: I2C write byte...
READ MOREIn the previous guide (here), we took a look how to configure the UART to transmit and receive data to/from PC using DMA. The limitation that we shall wait until the buffer is filled before we print the the received characters. In this guide, we...
READ MOREIn 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 recieve data. In this guide, we shall cover the following...
READ MOREn this guide, we shall discuss what is I2C and how to make an i2c bus scanner to scan the slave devices that connected to the i2c1 bus of STM32F103 In this guide we will cover the following: What is I2C I2C setup for stm32f1 I2C bus scanner code...
READ MOREIn the previous guide of the timer in STM32F1(here), we took a look how to configure the timer to operate in Encoder mode, in this guide, we shall use the timer to measure the number of pulses generated by the encoder. In this guide, we shall...
READ MOREIn the previous part (here), we saw how to configure the ADC to work in DMA mode with timer trigger. In this guide, we shall use feature called analog watchdog. This has benefits like monitoring level of water etc. In this guide, we shall cover...
READ MOREIn the previous guide of timer (here), we took a look how to configure the timer in PWM mode. In this guide, we shall use timer in output compare mode to toggle the LED on CH1 of TIM2. In this guide, we shall cover the following: What is output...
READ MOREIn this guide, we shall see how to interface ADXL335 Accelerometer sensor with STM32F4. Since this sensor is analog based sensor, we shall use DMA to handle the data from the adxl335. To setup multichannel ADC with DMA, please refer to this guide...
