An inline assembly statement is a string which specifies assembler code. The string can contain any instructions recognized by the assembler, including directives (we will not discuss assembler directives here). GCC does not parse the assembler instructions and does not know what they mean or even whether they are valid. Multiple assembler instructions can be placed together in a single asm string.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
