Wotchedwa B-L4S5I-IOT01A STM32 Discovery kit, yamangidwa mozungulira STM32L4 + microcontroller ndipo ili ndi masensa, chinthu chotetezeka (STSAFE-A110), NFC, Wi-Fi ndi Bluetooth 4.2.
Imafunikira kutsitsa kwaulere X-Cube-AWS v2.0 STM32Cube Expansion Pack, yomwe ndi seti ya malaibulale ndi zitsanzo zogwiritsira ntchito ma microcontroller omwe amakhala ngati zida zomaliza - ndipo ndipamene doko la FreeRTOS likuchokera. Doko, malinga ndi ST, ndioyenerera pa AWS.
Phukusi lokulitsa (kumanzere) limatsitsa, ngati lilipo, ntchito zofunikira zachitetezo kuzinthu zotetezeka munthawi ya MCU boot, panthawi yovomerezeka ya TLS yoloza ku seva ya AWS 'IoT Core', komanso pakutsimikizira kwa mpweya (OTA) ) sinthani kukhulupirika kwazithunzi za firmware komanso kutsimikizika. Imagwiritsa ntchito satifiketi yomwe idatetezedwa yomwe ili ndi mawonekedwe a AWS 'IoT Core Multi-Account Registration'.
"Ndi phukusi lokulitsa, zida zingagwiritsidwe ntchito ngati kapangidwe kofotokozera," malinga ndi ST. "X-CUBE-AWS v2.0 imatsimikizira kuphatikizidwa koyenera kwa njira yolumikizira muyezo wa FreeRTOS yolumikizira AWS mkati mwa chilengedwe cha STM32Cube. Izi zimalola ogwiritsa ntchito kugwiritsa ntchito FreeRTOS ndi STM32Cube popanda kupanga mapulogalamu ena. ”
MCU ndi Arm Cortex-M4 STM32L4S5VIT6 yokhala ndi 2Mbyte flash, 640kbyte RAM ndi accelerator ya encryption ya hardware.
Masensa okwera ndi:
- HTS221 capacitive digito wachibale-chinyezi ndi kutentha
- LIS3MDL 3-axis magnetometer
- LSM6DSL 3D accelerometer ndi 3D gyroscope
- LPS22HB mtheradi barometer
- VL53L0X nthawi yandege ndi chowunikira
- Ma maikolofoni awiri adijito
Kukulitsa, zolumikizira zimaperekedwa kuti azikulitsa matabwa omwe amagwirizana ndi Arduino Uno V3, ndi ma board a Pmod.
Tsamba lazogulitsa zida zili pano
Tsamba la ST la FreeRTOS lili pano
Phukusi lokulitsa limatha kutsitsidwa kuyambira pano - konzekerani mgwirizano wamalamulo. Chidule cha deta chikupezekanso patsamba lino.
Kuwongolera kwa AWS kuti muyenerere FreeRTOS kuli pano, ndi zolemba zina
