Open source STM32 book at Indiana University:
Lucky students at Indiana University might like to enrol on the [C – H]335 Computer Structures course run by Geoffrey Brown. If they do, they will be treated to a great introduction to the STM32 processor. The lab manual for the course is freely available to download.
The course covers the processor itself and a number of hardware modules including an LCD display, a serial interface, a Wii Nunchuk, an SD card and an audio amplifier. Using these modules will mean looking in some detail at programmed I/O, as well as common protocols such as asynchronous serial, SPI, and I2C; A/D based sensors, interrupts, and DMA.
