DLP-IO8 Compatible firmware/sketch for Arduino-like boards.
Provide a drop-in replacement for DLP-IO8 hardware using an off-the-shelve Arduino-compatible board when you don’t need the whole DPL-IO8 hardware characteristics.
- Digital out control (high/low)
- Digital in reading
- Analog in reading
- DS18B20 digital temperature sensor reading.
- Binary protocol
Due to the Arduino hardware, not all pins have analog-to-digital converter available. Only digital in/out will be available on all pins; Analog in reading will only be available on pins internally connected to the ADC.
Nothing done, a new project just started.
115200 bauds, no parity, 8 bits data, 1 stop bit, no flow control
This is the DLP-IO8 protocol, see http://www.dlpdesign.com/usb/io8.php for the original product and related datasheet.
