Is it possible to connect a RAM chip to two stm32? I assume that RAM should act as a data buffer from which the results of calculations can be read. Or is it better to use the third stm32 to make something like a separate module into which two stm32s will transfer data? The task is to combine the results of parallel calculations, save them for a while, and then read them all at once.

  • \$\begingroup\$ We don't know what your task is and how you are supposed to implement it. Yes you can share a RAM chip, there are many different RAM chips with different buses. Yes there are STM32 chips with megabyte of memory.. \$\endgroup\$

  • \$\begingroup\$ Yes it is possible. Specify type of you RAM ... for example with serial RAM (with SPI) it can be siply implemented - you just have to ensure that only one STM will have SPI active at a time. \$\endgroup\$ Apr 10 at 18:59
