Powering STM32H745 with bypass
<Moved from this thread.>Just to confirm, did anyone else got success by using: for STM32H745, to safely power the uC with just LDO no SMPS ?
I2C 800 KBS noise filtering features - where's the documentation?
I'm have the HAL_I2CEx_ConfigDigitalFilter call in my H743VIT6 code with the setting of zero.The AI recomends 4 to take out 8ns noise pulses, RF; etc., but where is the STM documentation or an AN about this, and the analogue filter?Its not in the RM0...
STM32 OCTOSPI immediate write after read fails deterministically.
Introduction: While testing the U575 with external PSRAM connected over OCTOSPI1, certain memory test scenarios fail deterministically. Setup:Using a STM32U575, connected on OCTO-SPI1 to PSRAM (IS66WVH8M8) 8MB in size. The STM is configured in memory...
