In just 30 seconds - anyone who remembers the early 1980s machines like the Spectrum will appreciate this is several times quicker. | In just 30 seconds - anyone who remembers the early 1980s machines like the Spectrum will appreciate this is several times quicker. | ||
It should be straight forward to get the Nanode (Arduino) I/O pins accessible from basic keywords - perhaps something like defining each pin as a keyword | It should be straight forward to get the Nanode (Arduino) I/O pins accessible from basic keywords - perhaps something like defining each pin as a keyword. | ||
As there are only 20 I/O pins on a ATmega - it's not going to take much program space to code them up. eg | |||
10 DOUT 4 = 1 // Set Dig 4 High | 10 DOUT 4 = 1 // Set Dig 4 High | ||
20 Let A = AIN 1 | 20 DOUT 6 = LOW // Set Dig 6 Low (alternative to 0) - Turns Nanode LED on... | ||
30 Sleep 2000 // Wait 2 seconds | |||
40 DOUT 6 = HIGH // Turn off Nanode LED | |||
50 Let A = AIN(1) // Get input from Analogue 1 (reads 0 to 1023) | |||
60 Print A | |||
70 Let B = A / 4 // re-range it to 0-255 | |||
80 AOUT 5 = B // set PWM (Analogue Write) on Dig 5 | |||
The Version of Tiny Basic with these analogue and digital I/O extensions can be found on this [https://gist.github.com/1520899 Github Gist.] | The Version of Tiny Basic with these analogue and digital I/O extensions can be found on this [https://gist.github.com/1520899 Github Gist.] | ||
Notes : Current version only works on pins 0 to 9 - (ie not D10 - D13) | |||
