I ) Communication avec liaisons UART, SPI ou I2c<\/b><\/u><\/span><\/span><\/h3>\n

Certains pin GPIO de la carte smoothieboard peuvent \u00eatre configur\u00e9 dans le fichier config pour qu’ils permettent des liaison s\u00e9ries SPI I2c ou UART<\/span><\/span><\/span><\/p>\n

Les pin P0.16 P0.15 P0.18 et P0.17 sont utilis\u00e9s comme liaison SPI par exemple par le Panel GLCD pour g\u00e9rer l’\u00e9cran LCD<\/p>\n

Dans le fichier config il y a\u00a0:<\/b><\/u><\/p>\n

# config settings<\/p>\n

panel.enable          true                    # set to true to enable the panel code\r\npanel.lcd             reprap_discount_glcd    # set type of panel\r\npanel.spi_channel     0                       # spi channel to use  ;\r\npanel.spi_cs_pin      0.16                    # spi chip select     ; GLCD EXP1 Pin 4\r\nSeul le Pin 0.16 (CS) est indiqu\u00e9 dans le fichier config, je suppose que le reste S\u00e9rial clock MOSI et MISO est cod\u00e9 dans le firmware\u00a0?\r\n\r\n\"\"<\/pre>\n
La liaison spi-card P0.6 est celle de la carte SD qui est reprise par le panel GLCD mais la config pour un lecteur carte sd externe est indiqu\u00e9 dans le fichier config \u00e0 partir d'une liaison I2c en bas de la carte\r\n\r\n# setup for external sd card on the GLCD which uses the onboard sdcard SPI port<\/span>\r\npanel.external_sd   true<\/b><\/span>      # set to true if there is an extrernal sdcard on the panel<\/span>\r\npanel.external_sd.spi_channel 1<\/b><\/span> # set spi channel the sdcard is on<\/span>\r\npanel.external_sd.spi_cs_pin  0.28<\/b><\/span>  # set spi chip select for the sdcard (or any spare pin)<\/span>\r\npanel.external_sd.sdcd_pin  0.27!^<\/b><\/span>  # sd detect signal (set to nc if no sdcard detect) (or any spare pin)\r\n\r\n\"\"\r\n<\/span><\/pre>\n
La carte smoothieboard peut communiquer avec les liaisons
\nSPI, I2c et UART<\/p>\n

II ) Communication avec n’importe quel pin GPIO avec les modules<\/b><\/u><\/span><\/span><\/h3>\n
Les cartes \u00e0 microcontroleurs ( Raspberry Pi, Arduino, Beaglebone, Smoothieboard \u2026 ) ont des entr\u00e9es sorties pr\u00e9vue pour les usages classiques, port USB, port r\u00e9seau, port \u00e9cran HDMI \u2026<\/span><\/span><\/p>\n
Les fonctions de ces cartes \u00e0 microcontr\u00f4leur sont extensibles en y connect<\/span>ant<\/span> des appareils, d\u2019autres cartes <\/span>\u00e9lectroniques.<\/span>
\n<\/span><\/p>\n
Les \u00e9l\u00e9ments externes qui seront des options utilis\u00e9s par la suite se connectent par l\u2019interm\u00e9diaire des connecteur <\/span>GPIO
\nGPIO<\/span><\/strong> signifie <\/span>G<\/b><\/span>eneral <\/span>P<\/span><\/strong>urpose <\/span>I<\/span><\/strong>nput\/<\/span>O<\/span><\/strong>utput, litt\u00e9ralement (<\/span>Entr\u00e9e\/Sortie pour un Usage G\u00e9n\u00e9ral<\/i><\/span>)<\/span><\/p>\n
Au lieu d\u2019\u00eatre regroup\u00e9 \u00e0 un seul endroit comme pour les carte Raspberry et Arduino.
\nLes ports GPIO de la carte smoothieboard sont r\u00e9partis un peu partout.\u00a0 <\/span>http:\/\/smoothieware.org\/pinout<\/span><\/span><\/a><\/strong><\/p>\n
Il y a \u00e9norm\u00e9ment de broches de connection GPIO de disponible dont certaines peuvent avoir des capacit\u00e9s particuli\u00e8res<\/p>\n
\"\"<\/p>\n
Les broches GPIO avec possibilit\u00e9 d\u2019interruption peuvent \u00eatre utilis\u00e9 pour des boutons pour modifier imm\u00e9diatement le d\u00e9roulement habituel de l\u2019usinage m\u00eame si celui ci est en cours.
\nPWM<\/strong> signifie P<\/strong>ulse W<\/strong>idth M<\/strong>odulation ( modulation de largeur d\u2019impulsions ) permet d\u2019avoir une sortie analogique pour par exemple moduler la vitesse de la broche \u00e0 partir de la carte.<\/p>\n
Chaque port GPIO est identifi\u00e9 par P<\/strong>(un nombre).(un nombre)<\/p>\n
Beaucoup de port GPIO sont libres d\u2019utilisation comme ceux ci-dessous encadr\u00e9s en rouge.
\nMais si certaines fonctions de la carte ne sont pas utilis\u00e9es il est possible d\u2019affecter les broches correspondante \u00e0 un usage g\u00e9n\u00e9ral GPIO
\nCe serait le cas pour les broches ici entour\u00e9es en orange. Par exemple le capteur endstop X min s\u2019il n\u2019est pas utilis\u00e9, sa broche P1.24<\/strong> pourrait \u00eatre affect\u00e9e \u00e0 autre chose.<\/p>\n
