STM32L100xC not working Topic is solved

[gclarkii]

Greetings,

I have the L100-Discovery board. I copied over the board specs from the L152 discovery board and changed the appropriate pins (mostly LED and MCU). The compile then bombed. After changing the MCU to STM32L151xCA from STM32L100xC, it compiled and ran just fine. I then started troubleshooting it.
I think it has something to do with the fact that the L100 does NOT have a E or D. When I created a special category(#7), and tell the system that D and E are false, it all works. I also went ahead and separated out the DAC, the 100xC has a single channel on DAC1 and DAC2 and not two channels on DAC1.

I've included the compile error.

Hi,

L100 is not yet supported, you may try to add it as follow:

- Add the required checks in hal_lld.h.
- Add a dedicated section in stm32_registry.h, you need to specify exactly which peripherals are present.
