A few questions on goto-statements, encapsulation, etc
Posted on December 31, 2016 at 23:25I am working with the STM32F405 microcontroller and I am trying to have a software UART use the same interrupt line (EXTI15_10_IRQn) as other interrupts (for example, button press interrupts). In a perfect world, ...
STM32F7 series need separate SDMMC PLL
Posted on December 31, 2016 at 19:56Hi all. The standard SDMMC bus speed is 24MHz which, on the STM32F7 series, is derived from the USB PLL48 clock source / 2. If we want to operate the SD card in High Speed mode, which has a maximum bus speed of 50...
