Last, the integration time set to 100 ms (the setting for room light or a target further away) and one brightness reading Y under it. Then a 50 ms wait between readings and the auto-zero every 10 readings, a Z window of 100 to 900 for 3 readings whose flag is printed after a second and cleared, one far-infrared reading (measured when asked), and the wait and the auto-zero back to their start-up values. The black and white calibration is stored for the port: later programs start with it.", "workspace": { "blocks": { "languageVersion": 0, "blocks": [ { "type": "evn_setup_start", "x": 30, "y": 30, "next": { "block": { "type": "evn_tcs3430_setup", "fields": { "PORT": "16" } } } }, { "type": "evn_program_start", "x": 30, "y": 160, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "text", "fields": { "TEXT": "Nothing in front of the TCS3430..." } } } }, "next": { "block": { "type": "evn_wait", "inputs": { "TIME": { "shadow": { "type": "math_number", "fields": { "NUM": 2000 } } } }, "next": { "block": { "type": "evn_tcs3430_calibrate", "fields": { "PORT": "16", "WHAT": "black" }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "text", "fields": { "TEXT": "Hold a white sheet about 1 cm in front of the TCS3430..." } } } }, "next": { "block": { "type": "evn_wait", "inputs": { "TIME": { "shadow": { "type": "math_number", "fields": { "NUM": 3000 } } } }, "next": { "block": { "type": "evn_tcs3430_calibrate", "fields": { "PORT": "16", "WHAT": "white" }, "next": { "block": { "type": "evn_tcs3430_gain", "fields": { "PORT": "16", "GAIN": "16" }, "next": { "block": { "type": "controls_repeat_ext", "inputs": { "TIMES": { "shadow": { "type": "math_number", "fields": { "NUM": 40 } } }, "DO": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_color", "fields": { "PORT": "16" } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_value", "fields": { "PORT": "16", "WHAT": "xyz()[0]" } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_value", "fields": { "PORT": "16", "WHAT": "xyz()[1]" } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_value", "fields": { "PORT": "16", "WHAT": "xyz()[2]" } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_value", "fields": { "PORT": "16", "WHAT": "ir()" } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_value", "fields": { "PORT": "16", "WHAT": "hsv().h" } } } }, "next": { "block": { "type": "controls_if", "inputs": { "IF0": { "block": { "type": "evn_tcs3430_sees", "fields": { "PORT": "16", "COLOR": "RED" } } }, "DO0": { "block": { "type": "text_print", "inputs": { "TEXT": { "shadow": { "type": "text", "fields": { "TEXT": "the TCS3430 sees red" } } } } } } }, "next": { "block": { "type": "evn_wait", "inputs": { "TIME": { "shadow": { "type": "math_number", "fields": { "NUM": 500 } } } } } } } } } } } } } } } } } } } } }, "next": { "block": { "type": "evn_tcs3430_integration", "fields": { "PORT": "16" }, "inputs": { "MS": { "shadow": { "type": "math_number", "fields": { "NUM": 100 } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "shadow": { "type": "text", "fields": { "TEXT": "integration time 100 ms, Y (brightness):" } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_value", "fields": { "PORT": "16", "WHAT": "xyz()[1]" } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "text", "fields": { "TEXT": "A reading every 2.78 ms + 50 ms now, the dark offset re-measured every 10 readings" } } } }, "next": { "block": { "type": "evn_tcs3430_wait", "fields": { "PORT": "16" }, "inputs": { "MS": { "shadow": { "type": "math_number", "fields": { "NUM": 50 } } } }, "next": { "block": { "type": "evn_tcs3430_autozero", "fields": { "PORT": "16", "NTH": "10" }, "next": { "block": { "type": "evn_tcs3430_window", "fields": { "PORT": "16", "PERS": "3" }, "inputs": { "LOW": { "shadow": { "type": "math_number", "fields": { "NUM": 100 } } }, "HIGH": { "shadow": { "type": "math_number", "fields": { "NUM": 900 } } } }, "next": { "block": { "type": "evn_wait", "inputs": { "TIME": { "shadow": { "type": "math_number", "fields": { "NUM": 1000 } } } }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_left_window", "fields": { "PORT": "16" } } } }, "next": { "block": { "type": "evn_tcs3430_clear_window", "fields": { "PORT": "16" }, "next": { "block": { "type": "text_print", "inputs": { "TEXT": { "block": { "type": "evn_tcs3430_value", "fields": { "PORT": "16", "WHAT": "ir2()" } } } }, "next": { "block": { "type": "evn_tcs3430_wait", "fields": { "PORT": "16" }, "inputs": { "MS": { "shadow": { "type": "math_number", "fields": { "NUM": 0 } } } }, "next": { "block": { "type": "evn_tcs3430_autozero", "fields": { "PORT": "16", "NTH": "127" } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } ] } } }
