Hello,I am in the process of designing a product which is based on the STM32-H7 and requires more RAM, somewhere in the 2-digit MB range (8 or 16 MB should do).As I understand, I have several options:Using SD-RAM with the Flexible Memory Controller (...
Hi,I work with a development team that is developing a product that has a STM32L4S9 MCU and a IS66WVH8M8ALL-100 HyperBus PSRAM.Recently, we found in the STM32L4 Errata that actually this MCU does not support PSRAM. We noticed that the self-refresh wa...

Greetings,Platform Details:GCC 10.3 + CMakeSTM32H723 Nucleo-144I am currently a bit struggling with the ADC Conversion via DMA. My software is working with many other ADCs, but for some reasons, if I am using following ADCs, the values from the DMA-C...
Hello everyone.I have 2 incremental encoders. One of them has the output voltage of signals A and B 5 volts and the other one 24 volts. I need to count the increments with stm32f4 and timers in the mode encoder. But I have to first convert the 5 and ...
I design a stm32h743 board without conformal coating, it works good, when I shacked board, stm32h743 failed and burnt.what's that reason?thank you
