1 I wrote drivers for the following devices:
3 * '''DC-motors''' - Both on/off cw/ccw and PWM drive.
4 * '''Stepper motors''' - With real-time stepping control, dynamic acceleration ramps, homing state-machine, etc.
6 * '''7-segement BCD and british-flag alphanumerical displays'''
7 * '''Alphanumerical LCD displays''' - Like the popular Hitachi HD44xxx controller.
8 * '''B/W bitmap LCD displays''' - Using a homebrew library to draw text and graphics (see DevLib).
9 * '''Thermal Printers''' - Both serial and full printing head control.
10 * '''Keyboards''' - Simple and matrix scan, with debounce and complex input gestures.
12 * '''A/D converters''' - Interrupt-driven, high-speed sampling and data processing
13 * '''D/A converters''' - Employing PWMs and other techniques
15 * '''Serial ports''' - RS232, RS485, SPI, I2C and many other custom serial lines, both interrupt-driven and software buffered.
16 * '''Ethernet''' - CS8900A and RTL8019 (NE2000 compatible).
17 * '''USB''' - With HCI drivers provided by manufacturer.
19 A few sample drivers for generic devices are available in DevLib.
