Fix PWM API for reading period and pulsewidth on LPC1768 #274

Closed multiplemonomials closed 2 months ago

multiplemonomials commented 2 months ago

Summary of changes

I've been working on testing out my new CI test shield with LPC1768, and I'm trying to actually fix the tests for this target so that I can prove the board itself works.

First up is the PwmOut tests: my CI shield tests discovered that the pwmout_read_period_us() and pwmout_read_pulsewidth_us() functions don't actually work and never have (since 2013 or earlier!). They return the counts value from the PWM register rather than a microseconds value as expected.

Additionally, pwmout_free() was never implemented, so stopping a PWM would not work as expected.

In this PR I updated these functions to actually work, so that LPC1768 can now pass my test shield PWM tests. Additionally, I fixed some compile errors related to earlier changes made to semihosting -- since semihosting is now an option instead of a TARGET_ define, there were some places in the code that were missed and had to be updated.
