Alternative to raw_input - Raspberry Pi Forums
i'm building system prompts user text input, submits web server using 1 of gpio pins. problem raw_input waits return key press before allowing pi read gpio pins. there way around this? can manually end process using code? here's code i've got far:
code: select all
#!/usr/bin/env python import rpi.gpio gpio subprocess import call time import sleep import urllib2, json, os #setup gpio pins gpio.setmode(gpio.bcm) gpio.setup(23, gpio.out) gpio.setup(25, gpio.in, pull_up_down=gpio.pud_down) tweet="" line="" block=[] space=" " hash = 140 #get prompt json json_url = "http://testurl.com/data" json_string = urllib2.urlopen(json_url).read() the_data = json.loads(json_string) data = the_data["data"] in data: type = i["typewriter"] prompt=i["prompt"] #subtract hash tag character count hash = hash - len(type) #upload function def upload(tweet): url = "https://testurl.com/tweet" try: call(["curl --data 'text=" + tweet + "' " + url], shell=true) except: print "fail" while true: if gpio.input(25): tweet = space.join(block) #add block of text spaces in between gpio.output(23, gpio.high) upload(tweet) sleep(1) else: gpio.output(23, gpio.low) try: line = line + raw_input("") except keyboardinterrupt: break #accounts line breaks within tweet block.append(line) #add separate lines line = ""
pygame allows poll keyboard keypresses directly if prefer that?
otherwise dont know of way.
.net/mono used let console.readkey() instead of readline handy purpose, wish there direct python equivalent.
