Ko te wāhitau pononga o bcm2835 me wiringPi hōtaka whakamātautau IIC kua tautuhia i roto i te iic.h file, e whakaatuhia ana i te ahua e whai ake nei:
Whakatikatika IIC_SLAVE_ADDR(taunoa ko 0x3C (e rite ana ki te 0x78)). Mo te example, huri ki te 0x3D, katahi ko te wahitau pononga IIC ko 0x3D (e rite ana ki te 0x7A);
- STM32 me C51 te kaupapa whakamatautau IIC i whakarereke mai i te wahitau taputapu
Ko te wahitau taputapu pononga o te STM32 me C51 te kaupapa whakamatautau IIC kua tautuhia i roto i te iic.h file, e whakaatuhia ana i te ahua e whai ake nei:
Whakakē tika IIC_SLAVE_ADDR (taunoa ko 0x78).Mo example, huri ki 0x7A, ka ko te wahitau pononga IIC ko 0x7A.
Ko te whakatinanatanga waehere korero IIC
Ko te kaupapa whakamatautau RaspberryPi te whakatinanatanga waehere korero IIC
WiringPi te kaupapa whakamatautau IIC waehere korero ka whakatinanahia i roto i te iic.c, pera me te whakaatu
Karanga tuatahi IIC_init ki te arawhiti, whakaturia te wahitau pononga IIC, tikina te taputapu IIC file whakaahua, ka whakamahi i te taputapu IIC file Kaituhi hei tuhi i te whakahau rehita me nga raraunga mahara. Ko te bcm2835 te kaupapa whakamatautau IIC waehere whakawhitiwhiti ka whakatinanahia ki iic.c, penei i raro nei:
Karanga tuatahi IIC_init ki te arawhiti, whakaturia te wahitau pononga IIC, tikina te taputapu IIC file whakaahua, ka whakamahi i te taputapu IIC file kaiwhakaahua hei tuhi i te whakahau rehita me te mahara
raraunga ia.
Ko te kaupapa whakamatautau Arduino IIC te whakatinana waehere korero
Ko te kaupapa whakamatautau Arduino Ko te waehere whakawhitiwhiti IIC ka whakatinanahia e U8glib, ko te tikanga whakatinana motuhake ka taea te korero ki te waehere U8glib
Ko te kaupapa whakamatautau STM32 te whakatinanatanga waehere korero IIC
Ko te kaupapa whakamatautau STM32 Ko te waehere korero IIC ka whakatinanahia i roto i te iic.c (he rereke nga rereketanga i waenga i nga whakatinanatanga MCU rereke), penei i te ahua e whai ake nei:
C51 te kaupapa whakamatautau IIC te whakatinana waehere korero
Ka whakatinanahia te kaupapa whakamatautau C51 IIC waehere korero i roto i te iic.c, penei i raro nei:
Pūmanawa noa
Ko tenei huinga whakamatautau exampme whakaatu te Hainamana me te reo Ingarihi, nga tohu me nga pikitia, na reira ka whakamahia te rorohiko modulo PCtoLCD2002. I konei, ka whakamaramahia te whakatakotoranga o te rorohiko modulo mo te kaupapa whakamatautau anake. Ko nga tautuhinga rorohiko modulo PCtoLCD2002 e whai ake nei: Ko te whakatakotoranga ira matrix ka tohua Waehere pouri te aratau modulo ka kowhiri i te aratau ahu whakamua (me whiriwhiri te kaupapa whakamatautau C51) Tangohia te tauira ki te whiriwhiri i te ahunga (turanga teitei i te tuatahi) (Me whiriwhiri te kaupapa whakamatautau C51 whakamuri (turanga iti i te tuatahi)) Ka kowhiria e te punaha tau huanga te tau hautekaumāono Ko te whiriwhiringa whakahōputu ritenga Hōputu C51 Ko te tikanga tautuhi e whai ake nei:
