python-cmsis-svd-parser

Class for processing SVD documents and transforming those into a dictionary and back again! Supports 1.3 version of the CMSIS-SVD schema. Helps A LOT if you are trying to generate the header files for your MCU projects!

What is returned

Dictionary returned after parsing is a nested one (obviously). Levels of hierarchy are as follows

• device - top of the dictionary
  • cpu - additional info about cpu employed in particular mcu
• peripherals - list of all peripherals
  • interrups - list of interrupts defined by the peripheral
• clusters | registers - peripheral may contain bare registers or clusters of registers. Clusters may be nested. Registers may not, obviously.
• fields - bit-fields of particular registers
• enumerated_values - name and list of enumerated values applicable for a given field
• enumerated_value - single enumerated value

Usage

# import the xml parser
import xml.etree.ElementTree as ET
# import the svd reader/writer
from SVDWriter import SVDWriter
from SVDReader import SVDReader

# load the file using xml parser
root = ET.parse('example.svd').getroot()
# parse the device file
device = SVDReader.process(root)

#
# DO YOUR STUFF HERE
#

# process back to the xml tree
xml = SVDWriter.process(device, make_pretty=True)
# convert to string and save to file
open("test.svd", "wb").write(ET.tostring(xml))
