Incazelo Esebenzayo
I-PmodACL2 isebenzisa Amadivayisi e-Analog ADXL362 ukuze inikeze idatha yokusheshisa ye-MEMS ebhodini lesistimu. Ngokujulile kwayo okungu-512-sample FIFO buffer, abasebenzisi bayakwazi view uchungechunge olude lwemicimbi ngaphambi kokuphazamiseka okucushiwe noma ukwazi nje ukuba nedatha yokusheshisa yokufinyelela ibhodi lesistimu lapho umsebenzisi ekuthola kulula kakhulu.
Ukuxhumana ne-Pmod
I-PmodACL2 ixhumana nebhodi lomsingathi ngephrothokholi ye-SPI. Ukuze ufunde kumarejista edatha asebhodini,
umugqa we-Chip Khetha kufanele uqale udonswe phansi bese uthumela i-byte yomyalo ozoyifunda kumarejista edatha (0x0B).
I-byte yekheli oyifunayo kufanele ithunyelwe ngokulandelayo, bese i-byte oyifunayo yamukelwa nge-MSB kuqala onqenqemeni lwewashi eliwayo. Ngenxa yokuthi isikhombisi sekheli sikhula ngokuzenzakalelayo kubhayithi yekheli elilandelayo, kuyenzeka ufunde amabhayithi amaningi ngokulandelana ngokuqhubeka ushaya umugqa wewashi le-Serial. Isibampisethi yemiyalo okufanele ifundwe kurejista ye-yaxis inikezwe ngezansi:
| Umyalo Funda | Ikheli lokuqala le-Y-eksisi | ||||||||||||||||
| 0 | 0 | 0 | 0 | 1 | 0 | 1 | 1 | 0 | 0 | 0 | 0 | 1 | 0 | 1 | 0 | ||
| Ibhayithi ye-LSB yedatha ye-Y-axis | Ibhayithi ye-MSB yedatha ye-Y-axis | ||||||||||||||||
| b7 | b6 | b5 | b4 | b3 | b2 | b1 | I-LSB | SX | SX | SX | SX | MSB | b10 | b9 | b8 | ||
Qaphela: Ibhithi ngalinye le-SX linani elifanayo nenani elibaluleke kakhulu ledatha ye-y-eksisi.
Ukuze ufunde kubhafa ye-FIFO, i-byte yomyalo yokubhalela kurejista yedatha (0x0A) kufanele iqale ithunyelwe ukuze sikwazi ukumisa irejista ye-FIFO Control (ikheli 0x28) ukuze sibonise ukuthi sifuna ibhafa ye-FIFO igcine idatha. Ngemva kokuthi i-ADXL362 isilungiselelwe ukusebenzisa isigcinalwazi se-FIFO, i-byte yomyalo okufanele ifundwe kubhafa ye-FIFO (0x0D) kufanele iqale ithunyelwe, bese ilandelwa amapheya amabhayithi edatha aqukethe ukuthi iyiphi i-eksisi elinganiswayo kanye nedatha yokusheshisa. Isibampisethi yemiyalo okufanele ifundwe ku-FIFO buffer inikezwe ngezansi:
Command Read FIFO Control Register Address Command FIFO Read
0 0 0 0 1 0 1 0 0 0 1 1 0 0 0 0 0 0 0 0 1 1 0 1
| Ibhayithi ye-LSB yedatha ye-Axis | Ibhayithi ye-MSB yedatha ye-Axis | ||||||||||||||||
| b7 | b6 | b5 | b4 | b3 | b2 | b1 | I-LSB | b15 | b14 | SX | SX | MSB | b10 | b9 | b8 | ||
Qaphela: Ibhithi ngalinye le-SX linani elifanayo nenani elibaluleke kakhulu ledatha ye-y-eksisi. I-b15 kanye ne-b14 zimelela ukuthi iyiphi i-eksisi idatha engenayo emele.

I-PmodACL2 futhi inezikhonkwane ezimbili zokuphazamiseka ezihlelekayo ezitholakalayo ukuze zisetshenziswe. Womabili la maphinikhodi angasethwa ukuze acuphe ukuphazamiseka kuzibangeli eziningi ezihlukene ezihlanganisa umsebenzi/ukungasebenzi (ukusiza ukunciphisa amandla esistimu), lapho ibhafa ye-FIFO igcwaliswa ileveli efiselekayo, lapho idatha isilungele ukubuyiswa, nezinye izibangeli.
Noma yimaphi amandla angaphandle asetshenziswa ku-PmodACL2 kufanele abe ngaphakathi kwe-1.6V kanye ne-3.5V. Ngakho-ke, ngamabhodi esistimu ye-Digilent, le Pmod kufanele isuswe ujantshi we-3.3V.
Ubukhulu bomzimba
Amaphini kunhlokweni kaphini ahlukaniswe ngamamayela ayi-100. I-PCB ingamayintshi angu-0.95 ubude ezinhlangothini ezihambisana nezikhonkwane ezisehlokweni likaphini kanye namayintshi angu-0.8 ubude ezinhlangothini eziqonde ngqo kunhlokweni kaphini.
