Mayelana nalolu hlelo lokusebenza

Isicelo sokubuyekeza i-firmware ye-Stm32 CPU nge-Bluetooth ngokusebenzisa amamojula we-Bluetooth-to-Serial.
Isekela amamojula anephrothokholi ye-bluetooth SPP yakudala (okungukuthi i-HC-06) kanye namamojula e-BLE ku-microcontroller cc254x (okungukuthi i-HM-10)

Ukugcwaliseka kwesicelo kusekelwe emibhalweni elandelayo evela enkampanini ye-STMicroelectronics.
1. Imodi yokuqalisa imemori yesistimu ye-AN2606 STM32 microcontroller
2. Iphrothokholi ye-AN3155 USART esetshenziswa kusiqalisi se-STM32


Isetshenziswa kanjani isicelo.

UKULUNGISELELA

1. Setha ukucushwa kwe-serial okulungile kumojula ye-Bluetooth-to-Serial. Kufanele kube amabhithi angu-8, alingane kanye nezinga loku-1 lokumisa kancane ne-baud ukusuka ku-1200 kuye ku-115200. Ukucushwa okusethwe kanjani kufundwe kudatha yemojuli yakho ye-Bluetooth-to-Serial.

2. Xhuma i-Bluetooth-to-Serial module ebhodini lakho le-Stm32.
Ngokuvamile i-r Stm32 isebenzisa uphayini olandelayo we-serial bootloader
I-PA10 (USART RX) ne-PA9 (USART_TX)

3. Vula imodi ye-bootloader ye-Stm32. Ungakwenza kanjani lokhu funda ku-AN2606. Ngokuvamile kufanele usethe izikhonkwane ezingu-BOOT0 kanye ne-BOOT1 zibe yinhlanganisela efanele ngokuvumelana nemodeli ye-CPU yakho.


UKUHLELA

1. Vula i-bluetooth ocingweni lwakho bese uxhuma ku-Bluetooth-to-Serial module
2. Khetha ifayela eline-firmware ofuna ukuyibhala.
Ifayela le-Firmware kufanele libe ngefomethi eyodwa yalezi ezilandelayo
- Intel hex
- Motorola S-Record
- Kanambambili eluhlaza
3. Setha izinketho zokubhala ozidingayo. Ungakhetha izinketho ezilandelayo
- Sula amakhasi adingekayo kuphela
- Susa ukuvikela ukufunda uma kunesidingo
- Setha ukuvikeleka kokufunda ngemva kokubhala
- Hamba i-CPU ngemva kokuhlela
4. Cindezela inkinobho ethi "Layisha ifayela ukuze likhanyise" bese ulinda ukuphela komsebenzi.


Okungeziwe kuhlelo lokusebenza kuyatholakala ekusebenzeni okulandelayo
- Ukusula
- Ihlola ifleshi ukuze uthole akunalutho
- Qhathanisa i-flash nefayela.
Ungakhetha lokhu kusebenza ngendawo efanelekile kumenyu.

Uhlelo lokusebenza luhlolwa ku-CPU elandelayo:
I-Stm32F072
I-Stm32F103
I-Stm32F302
I-Stm32F401
I-Stm32F411 ihlolwe ngumsebenzisi
I-Stm32L053
I-Stm32L152
I-Stm32L432
I-Stm32G071
I-Stm32G474


UMKHAWULO WOKUSEBENZISA
Ungenza kufikela ku-25 i-firmware ilayishe mahhala ngokuphelele.
Ngemva kokuthola lo mkhawulo ungathenga isevisi eyodwa kwezimbili
1. ukulayisha okungu-100 okwengeziwe
2. ukusetshenziswa okungenamkhawulo kwesicelo.
