Unifont on Wise Clock 3/4

This was a quick experiment inspired by WyoLum's EReader library: displaying Unicode characters on the 3216 display from Sure Electronics (as used in Wise Clock 3/4).

The fonts (developed by Roman Czyborra a very long time ago (1998!) and documented here) are defined in the file unifont.wff on the SD card. Before a character is displayed, its 32-byte definition is loaded from the file, starting from the calculated address.

Read analog input of Arduino Due board

Image
The Arduino Due Board has 12 analog inputs (pins from A0 to A11), each of which can provide 12 bits of resolution (i.e. 4096 different values). By default, the resolution of the readings is set at 10 bits, for compatibility with other Arduino boards. It is possible to change the resolution of the ADC with analogReadResolution(). The Due’s analog inputs pins measure from ground to a maximum value of 3.3V. Applying more then 3.3V on the Due’s pins will damage the SAM3X chip. The analogReference() function is ignored on the Due. Analog input pins on Arduino Due Board Example to read from Analog Input: int analogInputA0 = A0; int varA0; void setup() { Serial.begin(9600); analogReadResolution(12); //set ADC resolution to 12 bits } void loop() { varA0 = analogRead(analogInputA0); //read ADC input Serial.println(varA0, HEX); //print as HEX delay(1000); } Read Analog Input on Arduino Due If the code compiled with error: 'analogReadResolution' was not declared in t

Application Note of Cortex-M3 Embedded Software Development

Image
The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet). It is the first Arduino board based on a 32-bit ARM core microcontroller. The Application Note 179 Cortex™-M3 Embedded Software Development , from ARM Information Center, introduces the main features of the ARM Cortex™-M3 processor and describes different aspects of developing software for it. It also covers the migration of existing ARM projects to the Cortex-M3 platform. PDF version available at the bottom of the page.
