1.1. T-Echo
T-Echo ke boto ea nts'etsopele. E ka sebetsa ka boikemelo. E na le NRF52840 SOC, LoRa chip SX1262 le GNSS module.
NRF52840 e na le liprotocol tse ngata tse khonang ho sebelisana le protocol e felletseng. E na le ts'ehetso ea protocol bakeng sa Bluetooth LE.
NRF52840 e hahiloe ho potoloha 32-bit ARM® Cortex™-M4 CPU e nang le ntlha e phaphametseng e sebetsang ho 64 MHz. Yuniti ea cryptographic ea ARM TrustZone® CryptoCell e kenyellelitsoe onchip mme e tlisa mefuta e mengata e fapaneng ea likhetho tsa cryptographic tse sebetsang hantle ntle le CPU. E na le li-peripherals tse ngata tsa digital le li-interfaces tse kang lebelo le phahameng la SPI le QSPI bakeng sa ho kena-kenana le khanya ea ka ntle le lipontšo, PDM le I2S bakeng sa li-microphone tsa digital le molumo, le sesebelisoa sa USB se potlakileng bakeng sa ho fetisetsa data le phepelo ea matla bakeng sa ho nchafatsa betri.
Xinyuan e fana ka lisebelisoa tsa mantlha le lisebelisoa tsa software tse matlafatsang baetsi ba lits'ebetso ho aha mehopolo ea bona ho potoloha letoto la lisebelisoa tsa NRF52. Moralo oa nts'etsopele ea software o fanoeng ke Xinyuan o reretsoe ho nts'etsapele lits'ebetso tsa Internetof-Things (IoT) ka potlako, tse nang le LoRa, Bluetooth, GPS le taolo ea matla e feto-fetohang le likarolo tse ling tsa sistimi e tsoetseng pele.
T-Echo e ka boela ea tšoaroa ka letsoho, ea behoa leboteng kapa ea behoa holim'a tafole ho matha.
1.2. Arduino
Sete ea li-software tsa marang-rang tse ngotsoeng ka Java. Arduino Software IDE e nkiloe puong ea ho sebetsa ea Processing le tikolohong e kopanetsoeng ea ntlafatso ea lenaneo la Wiring. Basebelisi ba ka nts'etsapele lits'ebetso ho Windows/Linux/MacOS ho latela Arduino. E kgothaletswa ho sebelisa Windows 10. Windows OS e 'nile ea sebelisoa e le example tokomaneng ena ka sepheo sa ho etsa papiso.
1.3. Boitokisetso
Ho nts'etsapele likopo tsa NRF52840 o hloka:
- PC e na le sistimi e sebelisang Windows, Linux kapa Mac
- Toolchain ho aha Kopo ea NRF52840
- Arduino eo ha e le hantle e nang le API ea NRF52840 le mangolo a ho sebelisa Toolchain
- Boto ea NRF52840 ka boeona le thapo ea USB ho e hokahanya le PC.
2.1. Khoasolla software ea Arduino
