HOWTO: Use STM32 SPI half duplex mode
I’ve got my hands onto some STM32F030F4P6 ARM-Cortex M0 processors. Though touted as “32 cents 32-bit micro”, it is not that inexpensive from DigiKey in one-off quantity ($1.45). However it is still cheaper…
HOWTO: Write a display driver for SEGGER emWin
One lucky day you wake up to find your dream of creating sophisticated graphics user interface for MCU projects comes true, because STMicroelectronics has released a free version of SEGGER emWin for…
Opensource STM32 development
In an upcoming project I need a micro controller that operates: 1x 16-bit DAC (SPI); 1x 24-bit ADC (SPI); 1x 8-bit parallel LCD; 1x rotary encoder; 1x PWM fan; 1x fan tachometer; 1x…
Tutorial: 3.3V hacking for Arduino Nano
Hey I’m writing my first tutorial 🙂 During my recent OLED testing I wrote the software using Arduino Pro Mini 3.3 – the only Arduino board with 3.3V I/O (Lilipad may be the…
