The Brazilian students are at it again. First Blockly to BASIC, and now Ladder Logic to BASIC. Ladder Logic which is still used in control systems, is probably among the first graphical languages. Thanks to Leonardo, one of Miguel's students at Universidade Regional de Blumenau.
Pictured here is a binary counter in LadderLogic.
And here is a portion of the BASIC output. It covers the main loop, initialization and one of the rungs. Kind of reminds me of an Arduino Sketch.
sub Rung003 dim _S0 as integer _S0 = 1 Q05 = (T1AC AND 16.0) Q06 = (T1AC AND 32.0) Q07 = (T1AC AND 64.0) Q08 = (T1AC AND 128.0) endsub sub InitContext T1EN = 0 T1AC = 0 T1PRE = 256 T1B = 100000 T1DN = 0 T1TT_L = __VAR_TIME_L__ T1TT_H = __VAR_TIME_H__ endsub main: __init() InitContext() while (1) __input() __update() Rung001() Rung002() Rung003() __output() loop
