Alternative SDK for Ambiq Micro Apollo 1 and 2 MCU from Fujitsu (beta and under development)
Official low-level drivers for Apollo1 can be found here: https://ambiqmicro.com/apollo-ultra-low-power-mcus/apollo1-mcu/
Official low-level drivers for Apollo2 can be found here: https://ambiqmicro.com/apollo-ultra-low-power-mcus/apollo2-mcu/
Official low-level drivers for Apollo2Blue can be found here: https://ambiqmicro.com/apollo-ultra-low-power-mcus/apollo2-blue-mcu/
The alternative SDK for Ambiq Micro Apollo 1 and 2 MCUs is offering CMSIS compatible implementations. In the first step the API is not yet CMSIS driver API compatible, but this feature will be added as next step.
The SDK can be used with FEEU MCU Templates, already configured for the correct device.
The latest MCU Template for Apollo1 and software examples can be found here: http://www.feeu.com/apollo1
The latest MCU Template for Apollo2 and software examples can be found here: http://www.feeu.com/apollo2

Low-Level drivers are put into \library\lowlevel Configuration of low-level drivers is done in example\source\config\RTE_Device.h
Configuration of low-level drivers is done in example\source\config\RTE_Device.h
set DEBUG_OUTPUT to 1 to enable debug output by adding following line in example\source\config\RTE_Device.h
#define DEBUG_OUTPUT 1
Debug print is realized automatically if debugprint is not defined via printf:
#if (DEBUG_OUTPUT == 1) && (!defined(debugprint))
#define debugprint(...) if ((CoreDebug->DHCSR & (1 << CoreDebug_DHCSR_C_DEBUGEN_Pos)) != 0) printf(__VA_ARGS__)
#define debugprintln(...) debugprint(__VA_ARGS__); debugprint("\r\n")
