This example shows how to read data from the DE0 Nano integrated analog-to-digital converter using the SPI interface and then how to display this data using a MAX7219 LED Matrix.
Example pin assignments for DE0 Nano:
- CLOCK 50: R8
- LED_CLK: A2 (GPIO_02)
- LED_CS: B3 (GPIO_04)
- LED_DIN: A4 (GPIO_06)
- ADC_CS_N: A10
- ADC_SADDR: B10
- ADC_SCLK: B14
- ADC_SDAT: A9
In order to run a simulation, set the Library (in project files properties) to "utils" for all files added from within the "utils" subdirectory.
