 I wrote drivers for the following devices:
 
+=== Power devices ===
+
  * '''DC-motors''' - Both on/off cw/ccw and PWM drive.
  * '''Stepper motors''' - With real-time stepping control, dynamic acceleration ramps, homing state-machine, etc.
+ * '''Peltier cells''' and '''PWM heaters'''
+
+
+=== Sensors ===
+
+ * '''A/D converters''' - Interrupt-driven, high-speed sampling and data processing
+ * '''D/A converters''' - Employing PWMs, multiplexing of multiple channels and other advanced techniques
+ * '''GPIO lines''' - Direct or multiplexed, interrupt driven, polled, etc.
 
- * '''7-segement BCD and british-flag alphanumerical displays'''
+ * '''NTCs''', '''Thermo-couples''' - Temperature control
+ * '''Photocells''' - Light intensity measurement
+
+
+=== User interface ===
+
+ * '''7-segment BCD and british-flag alphanumerical displays'''
  * '''Alphanumerical LCD displays''' - Like the popular Hitachi HD44xxx controller.
  * '''B/W bitmap LCD displays''' - Using a homebrew library to draw text and graphics (see DevLib).
  * '''Thermal Printers''' - Both serial and full printing head control.
  * '''Keyboards''' - Simple and matrix scan, with debounce and complex input gestures.
+ * '''RTC Clocks''' - Like the Dallas DS1302 and compatibles.
+
+
+=== Communication and Networking ===
+
+ * '''Serial ports''' - RS232, RS485, SPI, I2C and many other custom serial lines, both interrupt-driven and software buffered.
+ * '''Ethernet''' - CS8900A and RTL8019 (NE2000 compatible).
+ * '''USB''' - With HCI drivers provided by manufacturer.
+
+
+=== Storage ===
+
+ * '''NOR flash devices''' - Using several programming algorithms.
+ * '''Serial EEPROMs''' - Like the I2C 24Cxxx chips.
+
+
+A few sample drivers for the most generic devices are available in DevLib.
