Kufotokozera Code Arduino IDE imagwiritsa ntchito C++ kupanga Arduino.
Mzerewu ndi chilengezo chamtsogolo. Izi zimagwiritsidwa ntchito kuuza Microcontroller kuti kupitilira mu pulogalamuyi ntchito ya `send_read_live_data_simple' ndipo ntchito ya `receive_read_live_data_simple' idzatchedwa.
Chotsatira ndi ntchito yokhazikitsa. Khodi iyi imayendetsedwa kamodzi kokha poyambitsa. Imayamba madoko a Serial0 ndi Serial1. Seri0 ndizomwe zikuwonetsedwa pazenera loyang'anira. Serial1 ndiye doko lolumikizirana ndi sensa.
Ichi ndiye chipika chachikulu, code iyi imapindika mobwerezabwereza. Mutha kuwona powerenga mayina a ntchitoyo kuti imatumiza pempho kuti muwerenge mtundu wosavuta wa mawonekedwe a data. Kenako imawerenga doko lolandila kuti muwerenge yankho. Pambuyo pa izi Microcontroller imadikirira 5000mS.
Ntchitoyi imalemba pempho loti mupeze serial data yosavuta struct ku serial port 1. Monga tanenera kale ngati muli ndi doko limodzi lokha muyenera kusintha seri1 kukhala seriyo. Kuti muwone mndandanda wathunthu wamalamulo, onani chikalata cha protocol ya Premier sensor Communications. Nali gawo la chikalata chomwe chimakuuzani zomwe muyenera kulemba pa lamulo ili:

Ntchitoyi imalumikiza ntchito yowerengera pomwe pali deta yomwe iyenera kulandilidwa kuchokera ku Platinum Sensor. Seri1.read() imawerenga zomwe zachokera ku seri1 zomwe zimalumikizidwa ku sensa ndikuzisindikiza pa Serial0 kuti ziwonekere pazowunikira. Munthu `|' kenako amasindikizidwa kuti aphwanye byte iliyonse yomwe imalandiridwa kuti imveke bwino pa serial monitor.
Izi zikatha, zimalemba mzere watsopano kwa serial monitor.

Kugwiritsa ntchito Serial.read()
Khodi yam'mbuyomu idangosindikiza zomwe zidalandilidwa ku serial monitor, ngati mukufuna kusunga zomwe zili mumitundu muyenera kuchitanso zina. Phukusi lomwe mumalandira lagawika kukhala ma byte, chifukwa cha izi mudzafunika kugwirizanitsa zina mwazinthu izi. Serial1.Read() imabweretsanso int (yomwe Arduino ndi 16 bits), komabe, ma bits oyambirira a 8 okha amagwiritsidwa ntchito. Chifukwa cha ichi tikhoza kukopera mu mtundu waung'ono wa data womwe uli ndi ma bits 8 okha, pamenepa ndigwiritsa ntchito char.
pamapaketi omwe ndiatali pang'ono, izi zimagwira ntchito bwino:
Pamapaketi omwe ali 2 mabayiti kapena 4 mabayiti aatali muyenera kulumikiza deta.
Mutha kuchita izi m'njira zosiyanasiyana, apa zomwe nditi ndichite ndikusiyidwa kusamutsa deta kenako OR.
Pogwiritsa ntchito code iyi, ngati readByte1 ndi 0x34 ndipo readByte2 ndi 0x12.
(int)readByte2
// izi zimatembenuza 0x12 kukhala 0x0012.
(int)readByte2 <<8
// izi zimasintha ma bits ndi byte kupanga 0x1200.
(int)readByte2 << 8 | readByte1 // izi ndiye zimapeza OR'ed, ndi 0x34 kupanga 0x1234.
Njira inanso yochitira izi ingakhale kuyika zikhalidwezo mugulu ndikusinthira mndandanda kukhala mtundu womwe mukufuna:

chars ndi baiti yaitali, pamene zoyandama ndi 4 byte utali. Chifukwa cha izi ngati tipanga mndandanda wa ma chars 4 okhala ndi zikhalidwe zathu momwemo ndikusintha mtunduwo kuti uyandama.
Pankhaniyi readArray ndi cholozera ku char array. (Float*)readArray this part imayiponya ku pointer to float ndiyeno * imawonjezedwa kutsogolo kuti ipeze mtengo wa choyandamacho.
Zosintha Zapamwamba
1. Serial.read() imabweretsanso int m'malo mwa char chifukwa zolakwika zidzabweretsa zolakwika. Pulogalamu yanu iyenera kuyang'ana izi.
2. uint8_t ndi uint16_t ziyenera kugwiritsidwa ntchito m'malo mwa char ndi int motsatana, popeza mitundu iyi ilibe kukula kwake (pa PC yanga int ndi 32 bits pomwe pa Arduino ndi 16 bits).
3. Protocol ya comms ili ndi zilembo za byte (zomwe zimadziwikanso kuti zilembo zowongolera), izi zikufotokozedwa mwatsatanetsatane mu tds0045 Premier sensor Communications protocol document. Chifukwa chake, paketi yosavuta yowerengera yamoyo nthawi zina imakhala yayikulu kuposa momwe amayembekezera.
