Note: Currently the I2C drivers on the Raspberry Pi lack some features. It reads the 10 ADC channels at 8-bit (10 bytes returned), then at 10-bit (20 bytes returned), and prints the results. Here is an example reading the ADC chip using Python on a Raspberry Pi. Heartbeat output to show unit is functioningĮach ADC input is read 3 times and the average value taken to reduce spurious valuesįor Arduino example code, check out the datasheet linked to above. Selectable 10-bit (2 bytes per ADC) or 8-bit (1 byte per ADC) output No additional components are required as it has its own built in oscillator clock circuit.ġ0 ADC input channels, each with 10 bit resolution (AN0 through AN9)Ĭonfigurable Slave Address between 40 and 47 allows up to 8 units to be added to your projectĪDC values are measured 1000 times per second (1 kHz) With this in mind we have programmed our own microcontroller to provide you with 10 additional ADC inputs available via I 2C as a slave device. V2Digital provides AJA's high-quality 10-bit conversion of component or composite analog video to SDI at either SD or HD resolutions utilizing a full 10-bit data path and 2x oversampling to.
However, if you are using many sensors and don’t have enough ADC inputs, or have used those pins for other functions, you either have to upgrade to a larger microcontroller with more inputs or resort to using an external (and expensive) ADC chip. The AJA V2Digital is a high-quality, cost-effective analog to digital video converter that's perfect for facilities needing to integrate signal types. These are measured with the use of the built-in Analogue to Digital Converters (ADC) included in microcontrollers. Some sensors have I 2C or SPI interfaces but there are still a great many which produce an analogue output voltage. In this example, embedded digital audio is being sent from a capture card breakout box to the. Many microcontroller projects involve the use of sensors like Accelerometers, Gyroscopes, Temperature, Compass, Barometric, Current, Proximity and others.
