Question

我想连接到GPS，然后等到找到正确的卫星以获取时间和日期。我的代码如下所示。有时这有时是行不通的... 问题： my_gps.date始终在while循环内（0,0,0），但有时rtc设置正确。我可以使用my_gps.timestamp作为while循环的条件，但有时它有些（0,0,0）旁边的值错误在其他情况下，它可以完美运行。（通常经过几次运行..（代码完成后，rtc是否仍在工作？）您能给我一些建议吗？最佳做法是什么？（我正在使用带有pytrack的lopy4）谢谢你，：）

#Setting up the gps:
py = Pytrack()
my_gps = MicropyGPS(local_offset=1,location_formatting='dd')
L76micropyGPS = L76micropyGPS(my_gps, py)
gpsThread = L76micropyGPS.startGPSThread()
print("Waiting for gps signal")
counter = 0
while (my_gps.date == (0, 0, 0) and counter < 10):
    print("Waiting for gps signal: "+str(counter)+" "+str(my_gps.date)+" "+str(my_gps.timestamp))
    counter +=1
    time.sleep(1)
time.sleep(2)
print("Date: "+str(my_gps.date))
print("GPS signal is found")
print("Time: "+str(my_gps.timestamp))
time.sleep(2)
print(my_gps.date[0])
print(my_gps.date[1])
print(my_gps.date[2])


print("Setting up the RTC")
rtc = machine.RTC()
print("RTC before init: {}".format(rtc.now()))
dateYear = int(str(20) + str(my_gps.date[2]))
rtc.init((dateYear, my_gps.date[1], my_gps.date[0], my_gps.timestamp[0], my_gps.timestamp[1], int(my_gps.timestamp[2]), 0, 0)) #seting up the rtc 
print("RTC is set : {}".format(rtc.now()))

根据GPS数据设置RTC
