cores/spi: Add new SPIMMAP core allowing doing SPI accesses directly from MMAP.
Implements a new SPIMMAP module, allowing accessing multiple SPI peripherals directly
from MMAP. It allows configurable SPI transactions: mode, bit order, and data width.
Developed and funded through a collaboration with MoTeC.
Example of integration:
# SPI MMAP ---------------------------------------------------------------------------------
spi_pads = Record([("clk", 1), ("cs_n", 8), ("mosi", 1), ("miso", 1)])
spi_mmap_tx_region = SoCRegion(origin=0x8000_0000, size=4096, cached=False)
spi_mmap_rx_region = SoCRegion(origin=0x8000_1000, size=4096, cached=False)
self.spi_mmap = SPIMMAP(
pads = spi_pads,
data_width = 32,
sys_clk_freq = sys_clk_freq,
tx_origin = spi_mmap_tx_region.origin,
rx_origin = spi_mmap_rx_region.origin,
tx_fifo_depth = 32,
rx_fifo_depth = 32,
)
self.bus.add_slave(name="spi_tx",
slave = self.spi_mmap.tx_mmap.bus,
region = spi_mmap_tx_region,
)
self.bus.add_slave(name="spi_rx",
slave = self.spi_mmap.rx_mmap.bus,
region = spi_mmap_rx_region,
)
self.irq.add("spi_mmap", use_loc_if_exists=True)

[> Description

|
|
|
|
--------------
|
|
|
|
|
|
First release of LiteX and the ecosystem of cores!
|
|
|
|
|
|
|
|
|
|
|
|
LiteX is a Migen/MiSoC based Core/SoC builder that provides the infrastructure to easily create
|
|
|
|
|
|
Cores/SoCs (with or without CPU).
|
|
|
|
|
|
|
|
|
|
|
|
The common components of a SoC are provided directly:
|
|
|
|
|
|
- Buses and Streams (Wishbone, AXI, Avalon-ST)
|
|
|
|
|
|
- Interconnect
|
|
|
|
|
|
- Common cores (RAM, ROM, Timer, UART, etc...)
|
|
|
|
|
|
- CPU wrappers/integration
|
|
|
|
|
|
- etc...
|
|
|
|
|
|
And SoC creation capabilities can be greatly extended with the ecosystem of LiteX cores (DRAM,
|
|
|
|
|
|
PCIe, Ethernet, SATA, etc...) that can be integrated/simulated/build easily with LiteX.
|
|
|
|
|
|
|
|
|
|
|
|
It also provides build backends for open-source and vendors toolchains.
