Commit 22a17230 authored by Paul Molloy's avatar Paul Molloy

Have things finally working with switch input and LED outputs.

Issue was due to messed up SRAM define in linker script. IDK what datasheet I was reading.. But I had the location and size completely wrong. That caused any access of SRAM to cause a hardfault of course. First happening when popping anything to the stack. Which also explains why I couldn't look at the stack to figure out the last called instruciton to point to where the issue was... copied stm32f0xx_*.h files over from STM32F0xx_StdPeriph_Driver/inc dir
