You got SPI, I2C, UART Timers and DMA and while their flavor may differ depending on the vendor, they should do about the same no matter what platform you are on. Sometimes you might have to do some exotic stuff when a chip uses non-standard interfaces, but most of the time the behavior should be fairly generic.
through the coupling link; in our case, this consists in primitives to initialize the SPI and DMA peripherals of the MCU and invoke inbound or outbound DMA transfers through the SPI channel. Synchronization events can be managed by means of wait-for-event primitives or interrupts on both the MCU and the accelerator.

May 12, 2018 · The STM32F7 processor has a really nice new peripheral- a ‘proper’ audio codec interface, – the SAI. … not the half baked I2S like it used to have. Now DMA is easy, 24 bit audio is easy etc etc. There is the option for using the switched mode supply or an analog LDO for the 3.3V. So I spent a full day and a half on it and it is ready to ... Intel ® Stratix ® 10 DX devices feature power efficient, high bandwidth, low latency transceivers. The transceivers are implemented on heterogeneous 3D System-in-Package (SiP) transceiver tiles, each containing up to 24 full-duplex transceiver channels.

SPI is a four wire synchronous serial interface and SPI devices can operate as either master devices or as slave devices. The PIC32 microcontroller labels the four SPI signals as Slave Select (SS), Serial Data Out (SDO), Serial Data In (SDI), and Serial Clock (SCK). A master device transmits SS, SDO, SCK, and receives SDI.

Serial Peripheral Interface Common serial interface on many microcontrollers Simple 8-bit exchange between two devices Master initiates transfer and generates clock signal Slave device selected by master One-byte at a time transfer Data protocols are defined by application Must be in agreement across devices Copying from DMA memory to the I2S peripheral is always in the background. Similarly, if using a microphone, copying audio samples from the I2S peripheral to DMA memory is done in the background. For the microphone case, the i2s.readinto(buf) method is used to pull data out of DMA memory.
+The "Serial Peripheral Interface" (SPI) is a four-wire point-to-point +serial link used to connect microcontrollers to sensors and memory. + +The three signal wires hold a clock (SCLK, often on the order of 10 MHz), +and parallel data lines with "Master Out, Slave In" (MOSI) or "Master In, +Slave Out" (MISO) signals. (Other names are also used.)

Both channels on, coupling DC. Set vertical sensitivity to lowest voltage where is not BW rejection. Set channels vertical positions so that other is 2div over center and other 2 div under center. Set horizontal speed to 1ms/div, if you can set persistence 1s or more
Broadcom offers a broad portfolio of industry leading PCIe Switches and PCIE bridges that are high performance, low latency, low power, and multi-purpose.
The ADC data sheet shows that the SPI transfers are very straight forward and the basic setup of the SPI module in the STM32F767xxx MCU will do the job well. You need to make sure that the number of bits (clock pulses) is set to 16, use NSS or a GPIO as you choose, you want CPHA and CPOL to either both be 0 or both be 1.

Oct 23, 2017 · The Colour and Stereo Surface Imaging System (CaSSIS) is the main imaging system onboard the European Space Agency’s ExoMars Trace Gas Orbiter (TGO) which was launched on 14 March 2016. CaSSIS is intended to acquire moderately high resolution (4.6 m/pixel) targeted images of Mars at a rate of 10–20 images per day from a roughly circular orbit 400 km above the surface. Each image can be ...
