Fujitsu Apollo Evaluation Platform The Fujitsu Apollo Evaluation Platform can be used with Ambiq Micro Apollo 1 or Apollo 2. The platform consists of two parts: The breakout board and the base board. The breakout boards of Apollo 1 and Apollo 2 are designed pin-compatible, so just some jumpers must be set on the base … [Read more…]
The alternative SDK for Apollo1 and Apollo2 was launched. The same SDK can be used for Apollo 1 and 2. Target is to be fully CMSIS compatible and make use of CMSIS compatible headfiles and register access as defined in CMSIS. In case of using core features like NVIC or ARM instructions like __NOP(); the … [Read more…]
The interrupt part of ARM Cortex M MCUs is described in CMSIS. The interrupt controller of ARM Cortex M MCUs is called NVIC. The NVIC is part of CMSIS and is decribed at the CMSIS website: https://www.keil.com/pack/doc/CMSIS/Core/html/group__NVIC__gr.html In general ARM Cortex M based MCUs having two types of IRQs: Core peripheral IRQs and MCU peripheral … [Read more…]
A Pulse Width Modelation (PWM) has a duty and a cycle. The duty can be something between 0% and 100% of the cycle time. For Ambiq Micro the CTIMER peripheral can be used to generate a PWM. GPIO setup First of all the GPIOs have to be set, see also Using GPIOs for more details. The … [Read more…]

The GPIOs of Apollo1 and Apollo2 series MCUs can be configured via a MUX for up to 8 different functionalities. Following schematic can be found in the datasheet in the chapter GPIO and Pad Configuration Module (Apollo1: chapter 6, Apollo2: chapter 7): The IO-cell itself can be configured in a complex way. The datasheet is … [Read more…]
A new feature of the new Apollo 2 MCU series is the so called SystemTimer. The SystemTimer or SysTimer is not the SysTick timer of the ARM Cortex M core, but adds new possibilities for real time behaviour scheduling in hardware with a little part of software. In addition it runs also in deepsleep modes! … [Read more…]
