  1. Hi, i seek a board based on virtex 6 FPGA and containing at less four analog inputs. can you advice me

      Hi moez,

      I have reposted your question here in the FPGA section of the forum.

      Thanks,
      JColvin

  4. thanks, i have to examine this
  5. Hi, i'm looking or FPGA board that including four ADC with about 1MSPS

    Pmode AD2

    Hi Sir I attempts de modify the code Nexys3_AD2_DA1_source for measuring a sinousidal signla at 50Hz in V0in voice, but the limitation by 100Hz from clkDivSecondary (whish is drived by clkDivMain compoent) component prevent this and my signal whish I can observe through screen by Rs232 connection at 115200Baud and using Matlab for this perpose, so the curve is too bad. the modification of frequency of ClkDivMain or clkDivSecondary does not mush, Then I try to modifie the finit machine by titing in pmpdAD2_ctrl component exactely the "waitCount" but in vain. how I can perform this, thank you a lot.
  7. I was able to control an induction motor and measure currents, fluxs, especially the latter is not accecible, so I estimate the speed: proper: estimate via spartant 3e with two analog entry that is integrated on this board, then we attempt to use another board like virtex5 or other to enhance the performance, the accuracy and reliability, to accomplish this I have to use PMODAD2 or PMODE AD5 .

  8. i attempt to use PMOD AD2 on simultaneous channels, with the configure registre writeCfg as mentionned in code Nexys3_AD2_DA1_source such as to select is performed by for MSB bits with underlying register, for example for channel in0 constant writeCfg "0001 0000"; for channel in1: writeCfg = "0010 0000"; and so on if we set writeCfg = 11110000 to obtain four simultaneous channels convertion, asn it mentionne in datasheet of 7999 but no signe of life, i have onle channel in0 however i tested each channel, separatley. thank for help pmodAD2_ctrl.vhd
