Nov 8, 2021 · Hi, We use chip LPC5526JBD64E to get the status of hard drives from the host via SGPIO. I was wondering whether the chip supports the SGPIO function? If the answer is yes, how to enable it? BR, carter

Aug 30, 2016 · I don't need a slice to generate an Interrupt (I use automatic SGPIO DMA transfers to move the data), but instead a SGPIO pin (the data qualifier input) to trigger an edge interrupt. Is SET_EN_3 still the right way to do this?

Sep 14, 2016 · The I2S bit clock goes to SGPIO, the I2S word select goes to SCT, and an external connection is required from an SCT output to an SGPIO pin to provide the clock qualifier function. An SGPIO slice (slice J, SGPIO3) is configured to provide its own idea of the WS signal. It is connected to CTIN_0 of the SCT via the GIMA.

1.3 I²C SGPIO Configuration SGPIO is a hardware feature of LPC4300 series. There are 16 SGPIO pins called from SGPIO 0 to SGPIO 15. SGPIO is one of the functions of LPC 4300 pins which can be chosen. SGPIO could work as standard GPIO pins, or do stream processing. So it provides a number of possibilities for interface implementation.

Jun 15, 2016 · Content originally posted in LPCWare by jgorsk on Mon Oct 29 11:59:22 MST 2012 I've been trying to use SGPIO with DMA. I want to transfer ten 11 bit words from memory to SGPIO REG_SS register, one at each SGPIO15 DMA triggering pulse. TRANSFERSIZE is set to 10 burst sizes are set to 1 transfer widt...

Apr 28, 2017 · Hi, on the M4 core of a board with LPC4357, I would like to implement SGPIO to get data at 5MHz as SIMPLEX SLAVE SPI (unidirectional stream, MISO not involved). Here is my configuration: SPI_CLK -> SGPIO11, SPI_CS -> SGPIO10 (qualifier), SPI_MOSI -> SGPIO12 I cannot make SGPIO slices work to get s...

Jun 15, 2016 · LPC_SGPIO->CTRL_ENABLED = (1L << 0); // Slice A enabled When CLKGEN_MODE bit is disabled, Slice A outputs a 50% duty cycle signal at SGPIO_CLK rate. However, when CLKGEN_MODE bit is set, there is no output, maybe because the external clock input is not configured correctly.

Aug 17, 2009 · On the backplane of my Super Micro SC113TQ-700CB chassis there are two connectors referred to as I2C / SGPIO connectors. The manual doesn't give much info about them. What exactly is the purpose of this connector? Is it something that must be used or an optional feature?

Jun 15, 2016 · 1. I switched from interrupts to DMA (SGPIO->MEM) by running a second SGPIO REG in parallel that shifts out a bit pattern to trigger the DMA on SGPIO14. 2. With this, the M0 has really nothing else to do, so I just run in a loop to detect a falling edge on SGPIO9 (LPC_SGPIO->GPIO_INREG) and switch DMA buffers and handle the packet when that ...
