Qhov rai

• Download tau thiab unzip lub demo rau koj lub Windows desktop, xa mus rau Raspberry
• Pi cov lus qhia los teeb tsa Windows software ib puag ncig kev teeb tsa.
• Nias thiab tuav lub pob BOOTSEL ntawm Pico, txuas lub USB ntawm Pico rau lub PC nrog MicroUSB cable. Ntshuam c lossis Python program rau Pico kom nws khiav.
• Siv cov cuab yeej serial rau view qhov chaw nres nkoj virtual ntawm Pico's USB enumeration los xyuas cov ntaub ntawv luam tawm, DTR yuav tsum tau qhib, thiab tus nqi baud yog 115200, raws li qhia hauv daim duab hauv qab no:

Lwm tus

• Lub teeb LED tsis yog siv los ntawm lub neej ntawd, yog tias koj xav siv nws, koj tuaj yeem siv 0R resistor ntawm R8 txoj haujlwm. Nyem rau view schematic daim duab.
• Lub INT tus pin ntawm DS3231 tsis siv los ntawm lub neej ntawd. Yog tias koj xav siv nws, koj tuaj yeem muab 0R resistor ntawm R5, R6, thiab R7 txoj haujlwm. Nyem rau view schematic daim duab.
• Solder R5 resistor, txuas INT tus pin rau GP3 tus pin ntawm Pico, txhawm rau txheeb xyuas cov xwm txheej tso tawm ntawm DS3231 lub tswb moos.
• Solder R6 resistor, txuas INT tus pin rau 3V3_EN tus pin ntawm Pico, kom tua lub zog Pico thaum lub tswb moos DS3231 tso tawm qis qis.
• Solder R7 resistor, txuas INT tus pin mus rau RUN tus pin ntawm Pico, kom rov pib Pico thaum DS3231 tswb moos outputs qis.
