Most have SPI and I2C controllers, but to execute program in such memory you must copy it in internal RAM and set that as executable. So that is a hassle and slows down execution, but you can store lots of data in I2C or SPI memories

Although it is true that some STM32 microcontrollers have external memory support, this feature is reported to be pretty glitchy at best and more often than not, does not work at all. An example of a good implementation of external memory support is on the RP2350 microcontroller, where it is reported to work flawlessly with QSPI ram.

Very interesting topic, its sold commercialy so nowadays its easy for people the to create their own RPi's with dedicated PCB software(like Altium or EasyEDA)

We can use SPI to add external memory for STM32 but how can RAM be increased externally? Can you name those STM32 controllers?

@youtube this is kind of the short video I want, as long as youtube is more education, there is no tiktok in my devices

Hello Mr. New person! Do you have a video on programming, uploading and running a blink program on a teensy 4.1? Secondly, do you know how what and how i can program an SPI OLED display 128 x 128 on the Teensy 4.1? Thanks!

I have question about buying components like stm32 or some powerfull Ic, is it okay to buy it from LCSC electronics or they in most cases provide copy of that components and will be better to buy from another distributor?

How i can know am i need external flash memory or no, how i can understand my program will be that huge that i will be need in external flash
