Simulink Coder Support Package for P-NUCLEO-WB55 board and model-based design examples for STM32WB55

Hello,I have the following questions about available support in Simulink:1) Is it planned to add Nucleo-WB55 to the set of supported boards in Simulink Coder (for example to communicate with hardware in Normal Mode Simulation using Connected IO)? If ...

STM32F072xx - How to detect VDDIO2 presence?

DS9826 states that "The VDDIO2 supply is monitored and compared with the internal reference voltage (VREFINT). When the VDDIO2 is below this threshold, all the I/Os supplied from this rail are disabled by hardware. The output of this comparator is co...

Parallel signaling using fsmc

Okay so I'm trying to use FSMC in order to control 16 bitlines and a (custom) clocksignal for driving multiple LED drivers. (the final goal see "data-signal")My first goal was to be able to drive the 16 bitlines, this works as expected. (see "without...
