Mojo FPGA Development Board Shield: 3 stappe

2024 Outeur: John Day | [email protected]. Laas verander: 2024-01-30 07:24

Koppel u Mojo -ontwikkelingsbord aan eksterne insette met hierdie skild.

Wat is die Mojo -ontwikkelingsraad?

Die Mojo -ontwikkelingsraad is 'n ontwikkelingsraad wat gebaseer is op die Xilinx spartan 3 FPGA. Die bord is gemaak deur Alchitry. FPGA's is baie handig waar verskeie prosesse gelyktydig uitgevoer moet word.

Wat sal jy nodig hê?

Voorrade

Mojo -ontwikkelingsraad

Gerber lêer

8 x 15k ohm weerstande (opsioneel*)

4 x 470 ohm weerstande

4 x 560 ohm weerstande

4 x CC sewe segment vertoon

4 x 3 mm LED's

4 x SPDT tasbare skakelaars

1 x 4 posisie DIP -skakelaar op die oppervlak

2 x 25 by 2 of 4 x 25 opskrifte

1x 2 by 5 pen bokskop

Soldeerbout

Soldeer

Fluks

*(as hierdie weerstande weggelaat word, moet interne pullup/down -down vir relevante penne geaktiveer word)

Stap 1: Laai Gerber op na die vervaardiger van u keuse

Vir my borde het ek by JLC PCB bestel.

Die enigste verandering wat ek aangebring het, was die kleur wat ek wou pas by die swart van die Mojo.

Stap 2: Raadsvergadering

By soldeer vind ek dit altyd nuttig om eers die laagste dele te soldeer, dus dit is 'n goeie idee om met die weerstande te begin.

R5, R6, R7, R8, R9, R10, R11 en R12 is 15k ohm weerstande wat gebruik word om die skakelaars af te trek (ignoreer dit as u interne pullup/pull down gebruik).

R1, R2, R3, R4 is 560 ohm weerstande wat verantwoordelik is vir die beperking van die stroom deur die 7 segment vertoning.

R13, R14, R15, R16 is 470 ohm weerstande wat verantwoordelik is vir die beperking van die stroom deur die 4 LED's.

Soldeer dan die dipskakelaar, tasbare skakelaars, LED's, sewe segmentskerms en boksopeningskoppelstuk in die volgorde.

Plaas nou die 25 by 2 (of 2 25 by 1) in die mojo om die penne in lyn te bring. Rig die skild met die penne in en soldeer dit op hul plek.

Stap 3: sagteware -opstelling

Vir sagteware wat na die Alchitry -webwerf verwys, sal u weet wat u nodig het om die Xilinx ISE te begin en te installeer. Maar verander die.ucf -lêer sodat dit weet watter penne gekoppel is aan wat belangrik is om u program aan die gang te kry.

Hier is die.ucf -lêer wat ek saam met die skild gebruik:

KONFIGEER VCCAUX = 3.3;

NET "clk" TNM_NET = clk; TIMESPEC TS_clk = PERIODE "clk" 50 MHz HOOG 50%; NET "clk" LOC = P56 | IOSTANDARD = LVTTL; NET "rst_n" LOC = P38 | IOSTANDARD = LVTTL; NET "cclk" LOC = P70 | IOSTANDARD = LVTTL; NET "spi_mosi" LOC = P44 | IOSTANDARD = LVTTL; NET "spi_miso" LOC = P45 | IOSTANDARD = LVTTL; NET "spi_ss" LOC = P48 | IOSTANDARD = LVTTL; NET "spi_sck" LOC = P43 | IOSTANDARD = LVTTL; NET "spi_channel" LOC = P46 | IOSTANDARD = LVTTL; NET "spi_channel" LOC = P61 | IOSTANDARD = LVTTL; NET "spi_channel" LOC = P62 | IOSTANDARD = LVTTL; NET "spi_channel" LOC = P65 | IOSTANDARD = LVTTL; NET "avr_tx" LOC = P55 | IOSTANDARD = LVTTL; NET "avr_rx" LOC = P59 | IOSTANDARD = LVTTL; NET "avr_rx_busy" LOC = P39 | IOSTANDARD = LVTTL; NET "Q [0]" LOC = P26 | IOSTANDARD = LVTTL; NET "Q [1]" LOC = P23 | IOSTANDARD = LVTTL; NET "Q [2]" LOC = P21 | IOSTANDARD = LVTTL; NET "Q [3]" LOC = P16 | IOSTANDARD = LVTTL; NET "S [0]" LOC = P7 | IOSTANDARD = LVTTL; NET "S [1]" LOC = P9 | IOSTANDARD = LVTTL; NET "S [2]" LOC = P11 | IOSTANDARD = LVTTL; NET "S [3]" LOC = P14 | IOSTANDARD = LVTTL; NET "pb [1]" LOC = P30 | IOSTANDARD = LVTTL; NET "pb [2]" LOC = P27 | IOSTANDARD = LVTTL; NET "pb [3]" LOC = P24 | IOSTANDARD = LVTTL; NET "pb [4]" LOC = P22 | IOSTANDARD = LVTTL; NET "sevsega [0]" LOC = P57 | IOSTANDARD = LVTTL; NET "sevsegb [0]" LOC = P58 | IOSTANDARD = LVTTL; NET "sevsegc [0]" LOC = P66 | IOSTANDARD = LVTTL; NET "sewe [0]" LOC = P67 | IOSTANDARD = LVTTL; NET "sevsege [0]" LOC = P74 | IOSTANDARD = LVTTL; NET "sevsegf [0]" LOC = P75 | IOSTANDARD = LVTTL; NET "sevsegg [0]" LOC = P78 | IOSTANDARD = LVTTL; NET "sevsegdp [0]" LOC = P80 | IOSTANDARD = LVTTL; NET "sevsega [1]" LOC = P82 | IOSTANDARD = LVTTL; NET "sevsegb [1]" LOC = P83 | IOSTANDARD = LVTTL; NET "sevsegc [1]" LOC = P84 | IOSTANDARD = LVTTL; NET "sewe [1]" LOC = P85 | IOSTANDARD = LVTTL; NET "sevsege [1]" LOC = P87 | IOSTANDARD = LVTTL; NET "sevsegf [1]" LOC = P88 | IOSTANDARD = LVTTL; NET "sevsegg [1]" LOC = P92 | IOSTANDARD = LVTTL; NET "sevsegdp [1]" LOC = P94 | IOSTANDARD = LVTTL; NET "sevsega [2]" LOC = P97 | IOSTANDARD = LVTTL; NET "sevsegb [2]" LOC = P98 | IOSTANDARD = LVTTL; NET "sevsegc [2]" LOC = P99 | IOSTANDARD = LVTTL; NET "sewe [2]" LOC = P100 | IOSTANDARD = LVTTL; NET "sevsege [2]" LOC = P101 | IOSTANDARD = LVTTL; NET "sevsegf [2]" LOC = P102 | IOSTANDARD = LVTTL; NET "sevsegg [2]" LOC = P104 | IOSTANDARD = LVTTL; NET "sevsegdp [2]" LOC = P111 | IOSTANDARD = LVTTL; NET "sevsega [3]" LOC = P114 | IOSTANDARD = LVTTL; NET "sevsegb [3]" LOC = P115 | IOSTANDARD = LVTTL; NET "sevsegc [3]" LOC = P116 | IOSTANDARD = LVTTL; NET "sewe [3]" LOC = P117 | IOSTANDARD = LVTTL; NET "sevsege [3]" LOC = P118 | IOSTANDARD = LVTTL; NET "sevsegf [3]" LOC = P119 | IOSTANDARD = LVTTL; NET "sevsegg [3]" LOC = P1120 | IOSTANDARD = LVTTL; NET "sevsegdp [3]" LOC = P121 | IOSTANDARD = LVTTL;

Onthou as u nie die aftrekweerstands geïnstalleer het om die penne in die.ucf mee te wysig nie

| AFTREK; o

As u die blok vir enigiets wil gebruik, is die verbindings soos volg. Links is die blokspeldnommer en regs die mojo -speldnommer wat u in u.ucf moet toewys:

pen 1 = 29

pen 2 = 51

pen 3 = 32

pen 4 = 41

pen 5 = 34

pen 6 = 35

pen 7 = 40

pen 8 = 33

pen 9 = GND

pen 10 = +V
