Abstract In 2013, a new stream cipher was proposed in Antal, E.-Hromada, V.: A new stream cipher based on Fialka M-125, Tatra Mt. Math. Publ. 57 (2013), 101-118. Its design was inspired and motivated by a Soviet encryption machine Fialka M-125. The authors proposed three versions of the cipher with different inner state bit-lengths. They provided the design, software implementation on a personal computer and a preliminary statistical and performance analysis of the cipher. In this article we extend their work by implementing all three versions of the cipher on two different micro-controllers: EBV SoCrates evaluation board [Official SoCrates webpage (EBV SoCrates evaluation board), www.rockerboards.org] and STM32F407VG [Official STM webpage (STM32F407VG), www.st.com]. We evaluate the performance of all implementations on both platforms. We also investigate the possibilities of performing a simple power analysis of the implementation of the 8-bit version of the cipher implemented on STM32F407VG micro-controller. It stems from our experiments that we are able to determine a part of the secret key of the cipher by observing the power trace (power consumption) of the encryption/decryption process

Image acquisition and wireless transmission is a key technology in the Internet of Things. This paper reports a ARM Cortex-M4 processor hand-held based Image acquisition and wireless transmission terminal. The terminal utilizes STM32F407VGT6 as its master controller, respectively. It uses Nordic nRF24L01 as its wireless transceiver module and OV9655 as its camera module. The system works in 2.4GHz ISM microwave band and can capture images and wirelessly transmit images within 20m indoors and 50m outdoors. The actual measurement of image acquisition and transmission shows that this terminal is highly stable and comparable in 2.4GHz microwave frequency.

The conventional phase difference measuring methods in the phase shift laser range finder are usually implemented with complex hardware circuits and phase discrimination algorithm. In this paper an FFT phase difference measuring method is designed and implemented based on STM32F407VG microcontroller. This method takes the advantage of the pre-set and fixed frequency of the beat signal by setting the analog-to-digital conversion rate precisely and making the input data length of FFT integral multiples of the beat signal period. In this way spectrum correction is no need. The hardware circuits and phase discrimination algorithm is simplified. The test results show that the phase difference measuring accuracy of 1/12000 is achieved.

Abstract The temperature detection and alarm system of power equipment is supposed to be used in power accidents caused by overheating. In our experiment, we build a system to detect the temperature of electrical power equipment. According to the actual temperature fitting curve, the whole system uses the Fiber Bragg Gratings as the signal sensing and transmission media, using the tunable Fabry-Perot (FP) cavity filter to demodulate the fiber and a SLED light source which is considered high reliability. System control and signal processing is carried out by the STM32F407ZGT6 microcontroller and its internal single-cycle DSP. The system has the characteristics of strong anti-interference ability, high reliability and precision, simple installation, convenient maintenance, remote signal transmission.

The world is moving towards the generation of electricity with renewable energy sources (RES) due to the deterioration of the green environment and trying to replace non-renewable energy resources. The real-time results are achieved with the help of an arm controller, having good controller efficiency with the Waijung toolbox, compatible with MATLAB using STM32ST-link utility. In this paper, the authors are focused on areas such as easy to implement controller efficiency, and real-time solutions for modified direct-control perturbation & observation (DC-P&O) technique based on 32- bit ARM Cortex microcontroller (STM32F407VGT6) with embedded programming using Waijung blocksets, which offers very expected outcomes of the problem to make the stand-alone system efficient with fast-tracking. The observation setup is tested with a 40-watt photovoltaic (PV) panel with resistive load for achieving its stability. The designed algorithm enhances the efficiency of the controller by 84.48% for the real-time parameters of the PV panel at maximum power point (MPP) for a 57% duty ratio.

Abstrak- Seiring meningkatnya kendaraan bermotor yang memerlukan bahan bakar minyak menyebabkan terbatasnya bahan bakar minyak sebagai sumber daya alam yang tidak dapat diperbaharui. Disisi lain, banyak pencemaran udara yang terjadi di Indonesia akibat dari reaksi pembakaran bahan bakar minyak tidak sempurna yang menyebabkan adanya hasil emisi berupa gas karbon. Penggerak dari kendaraan roda tiga elektrik adalah menggunakan motor induksi 3 phasa. Metode yang umum digunakan untuk mengendalikan kecepatan motor AC adalah mengubah tegangan output dari converter dengan cara mengubah PWM dari mikrokontroller. Pada alat ini menggunakan mikrokontroller ARM STM32F407VG untuk charging dan control motor menggunakan metode PI pada Multilevel boost converter agar nilai tegangan keluaran sesuai dengan yang diinginkan. Sistem pengaturan kecepatan motor ac menggunakan pengendali logika PI controller, masukan (error kecepatan dan set point) akan diproses guna mendapatkan nilai duty cycle sinyal PWM, nilai inilah yang digunakan sebagai acuan pembangkit PWM. Duty Cycle dari Pulse Widht Modulation (PWM) maksimal yang dikeluarkan adalah bernilai 46,6% sehingga nilai tegangan keluaran yang dihasilkan 537 V saat tegangan masukan 96 V
