Configuration changes, software updates and individual start-up screens can be uploaded onto the Barryvox via a mouse click and wireless interface. Software upgrades can be downloaded onto the Barryvox via a mouse click and wireless interface. Software Versions. W-Link Stick. The symbol name can be a function name or a variable name. Symbol granularity placements is possible due to compiler flags -ffunction-sections and -ffdata-sections.

If the user opts to remove these flags, then the symbol-granularity placements will not work. For example, with -ffunction-sections , separate sections are emitted for each function; with section names predictably constructed i.

This is not the case for string literals within the function, as they go to pooled or generated section names. With -fdata-sections , for global scope data the compiler predictably emits either. However, this is not the case for static data declared in function scope, as the generated section name is a result of mangling the variable name with some other information. The linker script template is the skeleton in which the generated placement rules are put into.

It is an otherwise ordinary linker script, with a specific marker syntax that indicates where the generated placement rules are placed. To reference the placement rules collected under a target token, the following syntax is used:. The example below is an excerpt from a possible linker script template. It defines an output section. All text sections of all object files under the archive libfreertos.

Since it is a rule generated from the default scheme, it comes first among all other rules collected under the same target name. Provide feedback about this document. Choose version Note In cases where multiple fragments of the same type and name are encountered, an exception is thrown. Note The only valid characters for fragment names and keys are alphanumeric characters and underscore. I have no idea what caused this to happen in the first place, though.

After doing this I started getting a bunch of link errors with barely any info, here's what I got: ". Improve this question. Add a comment. By default, AREF is 3. External shunt-type reference chips may be connected for lower reference voltage. When driven higher than AREF, these pins measure the maximum reading. Do not drive analog-only pins higher than 3. Analog Comparators These comparators allow an analog signal to be converted to digital, with a precisely defined voltage threshold for logic low versus high.

This may be used with analogWrite, or the Audio library. Capacitive Touch Sensing 12 pins can measure ground-coupled capacitance. The touchRead pin function is used. When Teensy GND is connected to earth ground, or to a conductive enclosure the user holds, these pins may be connected to electrodes to for a touch sensitive user interface.

Touch sensing can also be done on other pins with the CapacitiveSensor library , but the built in hardware on these 12 pins is more accurate and much faster.

PT is the least expensive DAC for good quality stereo signal output. Teensy Loader Application.
