  1. @jpeyron Another question related to my SPI ordering issue. If I call DjtgDisable(hif) in my DLL before I call SPIEnable(hif) would that disconnect/remove any previous jtag configuration and ensure that my SPIEnable() succeeded?
  2. Thanks. I have one other issue. I have 4 HS2's and I messed up the eeprom in one using FTDI's FT_Prog utility. Now FTDI's utuility will not recognize the device and I can't fix what I broke. Is there a utility to "fix" the eeprom in the HS2? Thanks.
  3. I have a system where I'm using 2 HS2 cables. One is used for SPI control and the other for Jtag. For my SPI interface, I have written a DLL using the ADEPT2 SDK, that allows me to specify the serial number of teh device to connect for SPI. Unfortunately both devices enumerate as device name "jtagHs2" and If I start my Xilinx Viivado Hardware manager before my SPI interface, the Vivado is taking over the device I want to use for SPI. If I start my spi interface first then vivado correctly picks up the HS2 I want to use for JTAG. Is there a way to prevent this, for example can I change the name "jtagHS2" in my SPI interface eeprom? Thanks, Patrick
  4. Problem solved. I had misread the specs as class A amplifier and was expecting to see normal sine wave output and to be able to plug a pair of headphones in directly. With class D the output is pulse width driven and the output waveform cannot be easily seen on a scope. Once I connected a speaker I was able to hear proper output and control volume.
  5. There is only one bit order on Is2, that is MSB first and I have verified that the data output is in correct order. The exact same bit pattern generates a perfect sine wave using the PMOD i2s module. I think my problem may be related to the amp itself, I am just plugging in a set of headphones which I don't think will work properly on a bridged amp output? I won't be able to hook up an actual speaker until tomorrow.
  6. I'm trying to play a sine wave 2KHz with 64KHz sampling rate using the AMP3 PMODule. I can see a 2Khz output on headphone jacks but it is basically a square wave and is hitting the rails. I've tried scaling down the samples but still cannot get a clean sine wave output. My sine wave generation works fine on the older i2s DAC PMODule. I'm using standalone mode, external MCLK (16.384Mhz) 256x multiplier (sample rate at 64K) and standard i2s. I get similar results when using BCLK as MCLK. here is an example of the 16 bit values I'm transmitting over i2s static const uint16_t sinTable[] = { 0x0000, 0x00c9, 0x0192, 0x025b, 0x0324, 0x03ed, 0x04b6, 0x057f, 0x0648, 0x0711, 0x07d9, 0x08a2, 0x096a, 0x0a33, 0x0afb, 0x0bc4, 0x0c8c, 0x0d54, 0x0e1c, 0x0ee3, 0x0fab, 0x1072, 0x113a, 0x1201, 0x12c8, 0x138f, 0x1455, 0x151c, 0x15e2, 0x16a8, 0x176e, 0x1833, 0x18f9, 0x19be, 0x1a82, 0x1b47, 0x1c0b, 0x1ccf, 0x1d93, 0x1e57, 0x1f1a, 0x1fdd, 0x209f, 0x2161, 0x2223, 0x22e5, 0x23a6, 0x2467, 0x2528, 0x25e8, 0x26a8, 0x2767, 0x2826, 0x28e5, 0x29a3, 0x2a61, 0x2b1f, 0x2bdc, 0x2c99, 0x2d55, 0x2e11, 0x2ecc, 0x2f87, 0x3041, 0x30fb, 0x31b5, 0x326e, 0x3326, 0x33df, 0x3496, 0x354d, 0x3604, 0x36ba, 0x376f, 0x3824, 0x38d9, 0x398c, 0x3a40, 0x3af2, 0x3ba5, 0x3c56, 0x3d07, 0x3db8, 0x3e68, 0x3f17, 0x3fc5, 0x4073, 0x4121, 0x41ce, 0x427a, 0x4325, 0x43d0, 0x447a, 0x4524, 0x45cd, 0x4675, 0x471c, 0x47c3, 0x4869, 0x490f, 0x49b4, 0x4a58, 0x4afb, 0x4b9d, 0x4c3f, 0x4ce0, 0x4d81, 0x4e20, 0x4ebf, 0x4f5d, 0x4ffb, 0x5097, 0x5133, 0x51ce, 0x5268, 0x5302, 0x539b, 0x5432, 0x54c9, 0x5560, 0x55f5, 0x568a, 0x571d, 0x57b0, 0x5842, 0x58d3, 0x5964, 0x59f3, 0x5a82, 0x5b0f, 0x5b9c, 0x5c28, 0x5cb3, 0x5d3e, 0x5dc7, 0x5e4f, 0x5ed7, 0x5f5d, 0x5fe3, 0x6068, 0x60eb, 0x616e, 0x61f0, 0x6271, 0x62f1, 0x6370, 0x63ee, 0x646c, 0x64e8, 0x6563, 0x65dd, 0x6656, 0x66cf, 0x6746, 0x67bc, 0x6832, 0x68a6, 0x6919, 0x698b, 0x69fd, 0x6a6d, 0x6adc, 0x6b4a, 0x6bb7, 0x6c23, 0x6c8e, 0x6cf8, 0x6d61, 0x6dc9, 0x6e30, 0x6e96, 0x6efb, 0x6f5e, 0x6fc1, 0x7022, 0x7083, 0x70e2, 0x7140, 0x719d, 0x71f9, 0x7254, 0x72ae, 0x7307, 0x735e, 0x73b5, 0x740a, 0x745f, 0x74b2, 0x7504, 0x7555, 0x75a5, 0x75f3, 0x7641, 0x768d, 0x76d8, 0x7722, 0x776b, 0x77b3, 0x77fa, 0x783f, 0x7884, 0x78c7, 0x7909, 0x794a, 0x7989, 0x79c8, 0x7a05, 0x7a41, 0x7a7c, 0x7ab6, 0x7aee, 0x7b26, 0x7b5c, 0x7b91, 0x7bc5, 0x7bf8, 0x7c29, 0x7c59, 0x7c88, 0x7cb6, 0x7ce3, 0x7d0e, 0x7d39, 0x7d62, 0x7d89, 0x7db0, 0x7dd5, 0x7dfa, 0x7e1d, 0x7e3e, 0x7e5f, 0x7e7e, 0x7e9c, 0x7eb9, 0x7ed5, 0x7eef, 0x7f09, 0x7f21, 0x7f37, 0x7f4d, 0x7f61, 0x7f74, 0x7f86, 0x7f97, 0x7fa6, 0x7fb4, 0x7fc1, 0x7fcd, 0x7fd8, 0x7fe1, 0x7fe9, 0x7ff0, 0x7ff5, 0x7ff9, 0x7ffd, 0x7ffe, 0x7fff, 0x7ffe, 0x7ffd, 0x7ff9, 0x7ff5, 0x7ff0, 0x7fe9, 0x7fe1, 0x7fd8, 0x7fcd, 0x7fc1, 0x7fb4, 0x7fa6, 0x7f97, 0x7f86, 0x7f74, 0x7f61, 0x7f4d, 0x7f37, 0x7f21, 0x7f09, 0x7eef, 0x7ed5, 0x7eb9, 0x7e9c, 0x7e7e, 0x7e5f, 0x7e3e, 0x7e1d, 0x7dfa, 0x7dd5, 0x7db0, 0x7d89, 0x7d62, 0x7d39, 0x7d0e, 0x7ce3, 0x7cb6, 0x7c88, 0x7c59, 0x7c29, 0x7bf8, 0x7bc5, 0x7b91, 0x7b5c, 0x7b26, 0x7aee, 0x7ab6, 0x7a7c, 0x7a41, 0x7a05, 0x79c8, 0x7989, 0x794a, 0x7909, 0x78c7, 0x7884, 0x783f, 0x77fa, 0x77b3, 0x776b, 0x7722, 0x76d8, 0x768d, 0x7641, 0x75f3, 0x75a5, 0x7555, 0x7504, 0x74b2, 0x745f, 0x740a, 0x73b5, 0x735e, 0x7307, 0x72ae, 0x7254, 0x71f9, 0x719d, 0x7140, 0x70e2, 0x7083, 0x7022, 0x6fc1, 0x6f5e, 0x6efb, 0x6e96, 0x6e30, 0x6dc9, 0x6d61, 0x6cf8, 0x6c8e, 0x6c23, 0x6bb7, 0x6b4a, 0x6adc, 0x6a6d, 0x69fd, 0x698b, 0x6919, 0x68a6, 0x6832, 0x67bc, 0x6746, 0x66cf, 0x6656, 0x65dd, 0x6563, 0x64e8, 0x646c, 0x63ee, 0x6370, 0x62f1, 0x6271, 0x61f0, 0x616e, 0x60eb, 0x6068, 0x5fe3, 0x5f5d, 0x5ed7, 0x5e4f, 0x5dc7, 0x5d3e, 0x5cb3, 0x5c28, 0x5b9c, 0x5b0f, 0x5a82, 0x59f3, 0x5964, 0x58d3, 0x5842, 0x57b0, 0x571d, 0x568a, 0x55f5, 0x5560, 0x54c9, 0x5432, 0x539b, 0x5302, 0x5268, 0x51ce, 0x5133, 0x5097, 0x4ffb, 0x4f5d, 0x4ebf, 0x4e20, 0x4d81, 0x4ce0, 0x4c3f, 0x4b9d, 0x4afb, 0x4a58, 0x49b4, 0x490f, 0x4869, 0x47c3, 0x471c, 0x4675, 0x45cd, 0x4524, 0x447a, 0x43d0, 0x4325, 0x427a, 0x41ce, 0x4121, 0x4073, 0x3fc5, 0x3f17, 0x3e68, 0x3db8, 0x3d07, 0x3c56, 0x3ba5, 0x3af2, 0x3a40, 0x398c, 0x38d9, 0x3824, 0x376f, 0x36ba, 0x3604, 0x354d, 0x3496, 0x33df, 0x3326, 0x326e, 0x31b5, 0x30fb, 0x3041, 0x2f87, 0x2ecc, 0x2e11, 0x2d55, 0x2c99, 0x2bdc, 0x2b1f, 0x2a61, 0x29a3, 0x28e5, 0x2826, 0x2767, 0x26a8, 0x25e8, 0x2528, 0x2467, 0x23a6, 0x22e5, 0x2223, 0x2161, 0x209f, 0x1fdd, 0x1f1a, 0x1e57, 0x1d93, 0x1ccf, 0x1c0b, 0x1b47, 0x1a82, 0x19be, 0x18f9, 0x1833, 0x176e, 0x16a8, 0x15e2, 0x151c, 0x1455, 0x138f, 0x12c8, 0x1201, 0x113a, 0x1072, 0x0fab, 0x0ee3, 0x0e1c, 0x0d54, 0x0c8c, 0x0bc4, 0x0afb, 0x0a33, 0x096a, 0x08a2, 0x07d9, 0x0711, 0x0648, 0x057f, 0x04b6, 0x03ed, 0x0324, 0x025b, 0x0192, 0x00c9, };
