2 Litšobotsi tsa Mehloli
2.1 Litšobotsi tsa matla:
[1] Amohela USB_OTG, USB_UART le EXT_IN mekhoa e meraro ea phepelo ea motlakase;
[2] Phepelo ea matla a dijithale: Phallo ea motlakase oa dijithale ke 3.3V, 'me potoloho e phahameng ea BUCK e sebelisetsoa ho fana ka matla bakeng sa ARM / FPGA / SDRAM, joalo-joalo;
[3] Mokotla oa FPGA o tsamaisoa ke 1.2V, hape o sebelisa potoloho e phahameng ea BUCK;
[4] FPGA PLL e na le palo e kholo ea li-circuits tsa analog, e le ho netefatsa ts'ebetso ea PLL, re sebelisa LDO ho fana ka matla a analog bakeng sa PLL;
[5] STM32F767IG e fana ka referense e ikemetseng ea analog voltage ho fana ka matla a referense bakeng sa on-chip ADC / DAC;
[6] E fana ka tlhokomelo ea matla le benchmarking;
2.2 Likarolo tsa ARM:
[1] STM32F767IG e phahameng ea ts'ebetso e nang le maqhubu a maholo a 216M;
[2] 14 katoloso ea tšebetso e phahameng ea I/O;
[3] Multiplexing le I / O, ho kenyelletsa le ARM e hahiloeng ho SPI / I2C / UART / TIMER / ADC le mesebetsi e meng;
[4] Ho kenyeletsoa 100M Ethernet, sehokelo sa USB-OTG se lebelo le holimo le ts'ebetso ea USB ho UART bakeng sa ho lokisa liphoso;
[5] Ho kenyeletsoa 32M SDRAM, segokanyimmediamentsi sa karete ea TF, sebopeho sa USB-OTG (e ka kopanngoa le U disk);
[6] 6P FPC debugging interface, adapter e tloaelehileng ho ikamahanya le sebopeho se akaretsang sa 20p;
[7] Ho sebelisa 16-bit parallel bus puisano;
2.3 Likarolo tsa FPGA:
[1] Letoto la Leholiotsoana la Altera la moloko oa bone FPGA EP4CE15F23C8N le sebelisoa;
[2] Ho fihla ho li-extensions tsa I/O tse phahameng tsa 230;
[3] FPGA e atolosa SRAM ea li-dual-chip ka matla a 512KB;
[4] Mokhoa oa ho hlophisa: ts'ehetso ea JTAG, AS, PS mode;
[5] Ts'ehetso ea ho kenya FPGA ka tlhophiso ea ARM;AS mosebetsi oa PS o hloka ho khethoa ka li-jumpers;
[6] Ho sebelisa puisano ea 16-bit parallel bese;
[7] FPGA debug port: FPGA JTAG port;
2.4 Likarolo tse ling:
[1] USB ea iCore4 e na le mekhoa e meraro ea ho sebetsa: DEVICE mode, HOST mode le OTG mode;
[2] Mofuta oa sebopeho sa Ethernet ke 100M e tletseng duplex;
[3] Mokhoa oa phepelo ea matla o ka khethoa ka jumper, sebopeho sa USB se tsamaisoa ka kotloloho, kapa ka hlooho ea pin (motlakase oa 5V);
[4] Likonopo tse peli tse ikemetseng li laoloa ke ARM le FPGA ka ho latellana;
[5] Mabone a mabeli a LED a iCore4 heterogeneous dual-core control industrial board a na le mebala e meraro: e khubelu, e tala le e putsoa, e laoloang ke ARM le FPGA ka ho latellana;
[6] Adopt 32.768K passive crystal ho fana ka nako ea nako ea sebele ea RTC bakeng sa tsamaiso;
