Raspberry Pi DS3231 Modul RTC nkenke maka Pico

Ozi ngwaahịa

Module RTC nkenke maka Pico bụ igwe elekere nke ọma dị elu emebere ka ejiri ya na bọọdụ microcontroller Raspberry Pi Pico. Ọ na-etinye mgbawa RTC dị elu nke DS3231 ma na-akwado nzikọrịta ozi I2C. Modul ahụ gụnyekwara
oghere batrị ndabere RTC nke na-akwado cell bọtịnụ CR1220 maka idobe oge ziri ezi ọbụlagodi mgbe agbapụrụ isi ike. Modul ahụ nwere ihe ngosi ike nke enwere ike ịgbanye ma ọ bụ nwee nkwarụ site na ịre ihe mgbochi 0 na jumper. Ọ bụ
emebere ya na nkụnye eji isi mee ihe maka mgbakwunye dị mfe na Raspberry Pi Pico

Ihe dị na Board:

1. DS3231 mgbawa RTC dị elu
2. Ụgbọ ala I2C maka nkwukọrịta
3. Oghere batrị nchekwa RTC na-akwado cell bọtịnụ CR1220
4. Ngosipụta ike (gbanyere ya site n'ịkwanye resistor 0 na jumper, nwere nkwarụ na ndabara)
5. Raspberry Pi Pico nkụnye eji isi mee dị mfe

Modul RTC nkenke maka Pico – Ntuziaka ojiji ngwaahịa

Koodu Raspberry Pi:

1. Mepee ọdụ Raspberry Pi.
2. Budata ma wepụ koodu ngosi na ndekọ Pico C/C++ SDK. Rịba ama na ndekọ ndekọ nke SDK nwere ike ịdị iche maka ndị ọrụ dị iche iche, yabụ ịkwesịrị ịlele ndekọ aha n'ezie. N'ozuzu, ọ kwesịrị ịbụ ~/pico/. Jiri iwu a: wget -P ~/pico https://www.waveshare.com/w/upload/2/26/Pico-rtc-ds3231_code.zip
3. Gaa na ndekọ Pico C/C++ SDK: cd ~/pico
4. Wepụ koodu ebudatara: unzip Pico-rtc-ds3231_code.zip
5. Jide bọtịnụ BOOTSEL nke Pico wee jikọọ eriri USB nke Pico na Raspberry Pi. Mgbe ahụ hapụ bọtịnụ ahụ.
6. Chịkọta ma mee pico-rtc-ds3231 examples iji iwu ndị a:

   cd ~/pico/pico-rtc-ds3231_code/c/build/ cmake .. make sudo mount /dev/sda1 /mnt/pico && sudo cp rtc.uf2 /mnt/pico/ && sudo sync && sudo umount /mnt/pico && sleep 2 && sudo minicom -b 115200 -o -D /dev/ttyACM0

7. Mepee ọnụ ma jiri minicom lelee ozi ihe mmetụta.

Python:

1. Rụtụ aka na ntuziaka Raspberry Pi ka ịtọlite ​​​​Micropython firmware maka Pico.
2. Mepee Thonny IDE.
3. Dọrọ koodu ngosi ahụ na IDE wee mee ya na Pico.
4. Pịa akara ngosi ọsọ iji mebie koodu ngosi MicroPython.

Windows:

Enyereghị ntuziaka maka iji Modul RTC Precision maka Pico na Windows n'akwụkwọ ntuziaka onye ọrụ. Biko rụtụ aka na akwụkwọ ngwaahịa ma ọ bụ kpọtụrụ onye nrụpụta maka enyemaka ọzọ.

Ndị ọzọ:

A naghị eji ọkụ ọkụ LED na modul na ndabara. Ọ bụrụ na ị chọrọ iji ha, ị nwere ike solder a 0R resistor na R8 ọnọdụ. Ị nwere ike view schematic eserese maka nkọwa ndị ọzọ.

Kedu ihe dị na bọọdụ

1. DS3231
   mgbawa RTC dị elu, ụgbọ ala I2C
2. Batrị ndabere RTC
   na-akwado cell button CR1220
3. Ngosipụta ike
   enyere ya aka site n'ịre ihe mgbochi 0Ω na jumper, nwere nkwarụ na ndabara
4. Raspberry Pi Pico nkụnye eji isi mee
   maka ijikọ na Raspberry Pi Pico, imewe nwere ike ikpokọta

Koodu Raspberry Pi

1. Mepee ọdụ Raspberry Pi
2. Budata ma mepee koodu ngosi na ndekọ Pico C/C++ SDK

1. Jide bọtịnụ BOOTSEL nke Pico, wee jikọọ eriri USB nke Pico na Raspberry Pi wee hapụ bọtịnụ ahụ.
2. Chịkọta ma mee pico-rtc-ds3231 examples

   

3. Mepee ọnụ na minicom onye ọrụ ka ịlele ozi ihe mmetụta.
