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'''. '''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.
+
+ * '''NTCs''', '''Thermo-couples''' - Temperature control
+ * '''Photocells''' - Light intensity measurement
+
+
+=== User interface ===
* '''7-segement 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.
- * '''A/D converters''' - Interrupt-driven, high-speed sampling and data processing
- * '''D/A converters''' - Employing PWMs and other techniques
+
+=== 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.
-A few sample drivers for generic devices are available in DevLib.
+
+=== Storage ===
+
+ * '''NOR flash devices''' - Using several programming algorithms.
+ * '''Serial EEPROMs''' - Like the I2C 24Cxxx chips.
