  1. Hello All! I have a Arty S7-50 Rev B Board. I am trying to control a mobile robot . I am also using a camera and to talk to both of them I need either I2c or serial communication. So far I created my system using microblaze with no problem. I tested leds, buttons, uart communication etc. My problem comes when I try to map pins other than buttons, leds or switch. I haven't been able to put the system to work. I Tried testing all I could think of before coming to the forums. I saved the project as another one, Created a new one from scratch etc etc and nothing so far. It have been many days if not weeks working in this part. I am pretty confidence about my design and about what I have to do with the robot. What I can't not is get signals out. So at this moment I'll give you some print screen of what I have. I could have some mistakes but it have been a lot of copy and paste and change so I got nowhere to go. I hope some of you could point me on where or how to go. I have this system with all this IP but at the beginning I was testing one by one. I need wither 2 uartlite o 1 I2c working. I know the microblaze, gpio0, timer and interrupt is working. Constraints: I had played a lot with this, this is the las I got. ## Switches set_property -dict { PACKAGE_PIN H14 IOSTANDARD LVCMOS33 } [get_ports { sw[0] }]; #IO_L20N_T3_A19_15 Sch=sw[0] set_property -dict { PACKAGE_PIN H18 IOSTANDARD LVCMOS33 } [get_ports { sw[1] }]; #IO_L21P_T3_DQS_15 Sch=sw[1] set_property -dict { PACKAGE_PIN G18 IOSTANDARD LVCMOS33 } [get_ports { sw[2] }]; #IO_L21N_T3_DQS_A18_15 Sch=sw[2] set_property -dict { PACKAGE_PIN M5 IOSTANDARD SSTL135 } [get_ports { sw[3] }]; #IO_L6N_T0_VREF_34 Sch=sw[3] ## Buttons set_property -dict { PACKAGE_PIN G15 IOSTANDARD LVCMOS33 } [get_ports { btn[0] }]; #IO_L18N_T2_A23_15 Sch=btn[0] set_property -dict { PACKAGE_PIN K16 IOSTANDARD LVCMOS33 } [get_ports { btn[1] }]; #IO_L19P_T3_A22_15 Sch=btn[1] set_property -dict { PACKAGE_PIN J16 IOSTANDARD LVCMOS33 } [get_ports { btn[2] }]; #IO_L19N_T3_A21_VREF_15 Sch=btn[2] set_property -dict { PACKAGE_PIN H13 IOSTANDARD LVCMOS33 } [get_ports { btn[3] }]; #IO_L20P_T3_A20_15 Sch=btn[3] ## Pmod Header JA #//set_property -dict { PACKAGE_PIN L17 IOSTANDARD LVCMOS33 } [get_ports { jap }]; #IO_L4P_T0_D04_14 Sch=ja_p[1] set_property -dict { PACKAGE_PIN L17 IOSTANDARD LVCMOS33 } [get_ports { led2 }]; #IO_L4P_T0_D04_14 Sch=ja_p[1] ## Pmod Header JD ##//set_property -dict { PACKAGE_PIN V15 IOSTANDARD LVCMOS33 } [get_ports { jap }]; #IO_L20N_T3_A07_D23_14 Sch=jd1/ck_io[33] set_property -dict { PACKAGE_PIN T13 IOSTANDARD LVCMOS33 } [get_ports { tx_1 }]; #IO_L21P_T3_DQS_14 Sch=jd2/ck_io[32] set_property -dict { PACKAGE_PIN R11 IOSTANDARD LVCMOS33 } [get_ports { rx_1 }]; #IO_L21N_T3_DQS_A06_D22_14 Sch=jd3/ck_io[31] set_property -dict { PACKAGE_PIN T11 IOSTANDARD LVCMOS33 } [get_ports { tx_0 }]; #IO_L23N_T3_A02_D18_14 Sch=jd9/ck_io[27] set_property -dict { PACKAGE_PIN U11 IOSTANDARD LVCMOS33 } [get_ports { rx_0 }]; #IO_L24P_T3_A01_D17_14 Sch=jd10/ck_io[26] set_property -dict { PACKAGE_PIN V15 IOSTANDARD LVCMOS33 } [get_ports { leds[0] }]; #IO_L16N_T2_A27_15 Sch=led[2] set_property -dict { PACKAGE_PIN U12 IOSTANDARD LVCMOS33 } [get_ports { leds[1] }]; #IO_L17P_T2_A26_15 Sch=led[3] set_property -dict { PACKAGE_PIN V13 IOSTANDARD LVCMOS33 } [get_ports { leds[2] }]; #IO_L17N_T2_A25_15 Sch=led[4] set_property -dict { PACKAGE_PIN T12 IOSTANDARD LVCMOS33 } [get_ports { leds[3] }]; #IO_L18P_T2_A24_15 Sch=led[5] ## USB-UART Interface set_property -dict { PACKAGE_PIN R12 IOSTANDARD LVCMOS33 } [get_ports { uart_rxd_out }]; #IO_25_14 Sch=uart_rxd_out set_property -dict { PACKAGE_PIN V12 IOSTANDARD LVCMOS33 } [get_ports { uart_txd_in }]; #IO_L24N_T3_A00_D16_14 Sch=uart_txd_in ## ChipKit I2C set_property -dict { PACKAGE_PIN J14 IOSTANDARD LVCMOS33 } [get_ports { ck_scl }]; #IO_L24N_T3_RS0_15 Sch=ck_scl set_property -dict { PACKAGE_PIN J13 IOSTANDARD LVCMOS33 } [get_ports { ck_sda }]; #IO_L24P_T3_RS1_15 Sch=ck_sda ## Configuration options, can be used for all designs set_property BITSTREAM.CONFIG.CONFIGRATE 50 [current_design] set_property CONFIG_VOLTAGE 3.3 [current_design] set_property CFGBVS VCCO [current_design] set_property BITSTREAM.CONFIG.SPI_BUSWIDTH 4 [current_design] set_property CONFIG_MODE SPIx4 [current_design] ## SW3 is assigned to a pin M5 in the 1.35v bank. This pin can also be used as ## the VREF for BANK 34. To ensure that SW3 does not define the reference voltage ## and to be able to use this pin as an ordinary I/O the following property must ## be set to enable an internal VREF for BANK 34. Since a 1.35v supply is being ## used the internal reference is set to half that value (i.e. 0.675v). Note that ## this property must be set even if SW3 is not used in the design. set_property INTERNAL_VREF 0.675 [get_iobanks 34] Schematic Elaborated Design: From what I see eveything it is fine, isn't it ? I/O Pots on Schematic I/O Ports on Synthesized Design Code of Sliding LEDS using timer on LEDS: This is funny, these are some sliding leds. It does not matter where I put / map this pins on contraints, this always light the leds. I was tring to map this in pmod header JD but it just ligh the leds. Serial Test: Here the USB serial workf fine with the PC but the other 2 are sending nothing. I2C selftest. The selftest failed, I know it fails on XIic_SelfTest This board is brand new, I only have it for a few weeks. I havent connected anything to the ports. I measured pins either with a tester or with a analog discovery so not short ciruits or similar have been produced. Any help would be apreciated. Edwin
