    Pmod ALS

    Hi, I am new to this forum so still getting used to things. I am trying to implement the Pmod ALS on an FPGA, and I require to comply with the SPI protocol. I understood the protocol, but the only problem I have is this. "The PmodALS reports to the host board when the ADC081S021 is placed in normal mode by bringing the CS pin low, and delivers a single reading in 16 SCLK clock cycles. The PmodALS requires the frequency of the SCLK to be between 1 MHz and 4 MHz. The bits of information, placed on the falling edge of the SCLK and valid on the subsequent rising edge of SCLK, consist of three leading zeroes, the eight bits of information with the MSB first, and four trailing zeroes." As far as I know, 3+8+4=15, and not 16, so where is the extra clock cycle and what is it doing? Is the sensor providing 4 irrelevant numbers before the 8-bit of information and then 4 irrelevant numbers again? Any help will be appreciated. Thanks.
  2. Good morning everyone, I am currently developing a computer application in Matlab with help of VHDL and the Nexys 4 DDR, my problem is that I need to send a vector of 16 or more bits through an aurt module, the aurt module only sends 8 bits but I need to send more bits. anyone have any idea how to receive more than 8 bits per aurt? , I know that you should make the matrix reception module in vhdl and I was trying with this module that I have, but it does not work, and I have no idea how to do it to receive matrix. thanks. recepciĆ³n.txt
