Ebizwa nge-B-L4S5I-IOT01A STM32 Discovery kit, yakhiwe eduze kwe-STM32L4 + microcontroller futhi inezinzwa, i-element ephephile (STSAFE-A110), NFC, Wi-Fi ne-Bluetooth 4.2.
Idinga i-X-Cube-AWS v2.0 STM32Cube Expension Pack yamahhala, okuyisethi yemitapo yolwazi nezibonelo zohlelo lokusebenza kuma-microcontroller asebenza njengamadivayisi wokugcina - futhi kulapho ichweba leFreeRTOS livela khona. Itheku, ngokusho kwe-ST, lifanelekile ku-AWS.
Iphakethe lokunweba (kwesobunxele) liyalayisha, lapho likhona, imisebenzi ebaluleke kakhulu kwezokuphepha entweni evikelekile ngesikhathi senqubo yokuqalisa i-MCU, ngesikhathi sokuqinisekiswa kwedivayisi ye-TLS ebheke kuseva ye-AWS 'IoT Core', nangesikhathi sokuqinisekiswa komoya (OTA) ) buyekeza ubuqotho besithombe se-firmware nobuqiniso. Sisebenzisa isitifiketi esinikeziwe sezinto ezivikelekile ngesici se-AWS 'IoT Core Multi-Account Registration'.
"Ngephakethe lokunweba, ikhithi ingasetshenziswa njenge-design design," ngokusho kwe-ST. “I-X-CUBE-AWS v2.0 iqinisekisa ukuhlanganiswa okufanele kohlaka lokuxhuma olujwayelekile lwe-FreeRTOS ngaphakathi kwendawo ye-STM32Cube. Lokhu kuvumela abasebenzisi ukuthi basebenzise iFreeRTOS ne-STM32Cube ngaphandle kokwenza isoftware eyengeziwe. ”
I-MCU iyi-Arm Cortex-M4 STM32L4S5VIT6 ene-2Mbyte flash, i-640kbyte RAM kanye ne-accelerator yokubethela i-hardware.
Izinzwa zebhodi yilezi:
- I-HTS221 capacitive digital isihlobo-umswakama nokushisa
- I-LIS3MDL 3-axis magnetometer
- I-LSM6DSL 3D accelerometer ne-3D gyroscope
- I-barometer ephelele ye-LPS22HB
- Isikhathi se-VL53L0X sendiza nendiza yokuthinta isenzo
- Imibhobho emibili yedijithali
Ngokwandiswa, izixhumi zihlinzekelwa amabhodi wokunweba ahambisana ne-Arduino Uno V3, namabhodi wePmod.

Iphakethe lokunweba lingalandwa kusukela lapha - lungela isivumelwano selayisense. Umfushane wedatha uyatholakala kuleli khasi.
Umhlahlandlela we-AWS we-FreeRTOS ofanelekayo ulapha, neminye imibhalo
