1. Background
I have done a project on STM32 low-power signal acquisition before, using the STM32L031 microcontroller. The project requirements are as follows:
The device is powered by a battery, dete...
Engineering changes (ECOs) drive up design costs and cause significant delays in product development, which in turn delays time to market. However, most ECOs can be avoided by carefully considering se...
