Tsohle file mabitso a lokela ho ba alpha-numeric. MyLOG1.txt e lokile, empa Lumela !e _.txt e kanna ea se sebetse.
Sebelisa 9600 Baud
OpenLog e tsoa ho ATmega328 mme e na le palo e lekanyelitsoeng ea RAM (2048 bytes). Ha o romella litlhaku tsa serial ho OpenLog, litlhaku tsena lia senyeha. Tlhaloso e Nolofalitsoeng ea Sehlopha sa SD e lumella karete ea SD ho nka ho fihla ho 250ms (karolo ea 4.6.2.2 Ngola) ho rekota thibela ea data ho memori ea flash.
Ho 9600bps, ke li-byte tse 960 (li-bits tse 10 ka motsotsoana). Ke 1.04ms ka baiti ka 'ngoe. OpenLog hajoale e sebelisa 512 byte e amohelang buffer kahoo e khona ho boloka litlhaku tse ka bang 50ms. Sena se lumella OpenLog ho amohela ka katleho litlhaku tsohle tse tlang ho 9600bps. Ha o ntse o eketsa sekhahla sa baud, buffer e tla tšoarella nako e nyane.
OpenLog Buffer Ho Feta Nako
| Baud Rate | Nako ka bate | Nako Ho fihlela Buffer e felile |
