Working closely with STM32CubeIDE Version: 1.13.1 I must accept it is much more convenient than it used to be. Now all FreeRTOS threads are displayed correctly in debug session. In case of a HardFault there is no need anymore to search through the st...

All of these are products designed for different tasks, but they work together.CubeMX is a standalone MCU configuration tool. The same functionality is also built in to the CubeIDE (with very minor differences)So, sometimes it is easier to use just ...

About 10 years ago I have tested RGB->HDMI bridge (I believe it was from TI) and it was working fine in HD mode (720p) because STM32F429 was too slow for FHD (1080p). But RGB->CVBS (Analog Devices, composite TV) bridge test failed because I was unabl...
