As long as my .ioc file has the linesVP_EXTMEM_MANAGER_SIG_Activate_EXTMEM.Mode=Activate_EXTMEM VP_EXTMEM_MANAGER_SIG_Activate_EXTMEM.Signal=EXTMEM_MANAGER_SIG_Activate_EXTMEM in it, CubeIDE and CubeMX will be unable to open it with the error:Cannot ...

My question today is kind of simple: I am using the SMPS to supply power to the MCU. Can I also use the SMPS to supply power to a NOR flash chip (W25 by Winbond, the exact chip doesn't matter, but it would be 1.8V with at least 64 Mbit size), and the...

I wanted to use the STM32F439 timers, any of them but timer 8 seems to be the best one with my current peripherals, to act as a trigger source. Basically, the timer would drive a pin low, and at specific counts of the timer, drive the pin high for ~5...

I figured out the real issue:I wanted to use NOR flash on the listed MCU. The way I set it up was that the first 2 MB of the chip was used for the boot sector, and the remaining 62 MB of the chip was used for the application sector. This causes the i...

>Or: are you asking using the SMPS in/on MCU and powering external stuff from it?(not possible, not intended)The question was using the SMPS on the MCU to supply power for external components. Due to the way one is supposed to implement the SMPS on a...

SPI appears to be the easiest option.The minimal gap between pulses is 20 clock ticks. The 22000 cycles is how long the entire thing will be, from the start of sending pulses to the end. The SPI method would essentially just be an array of about 750 ...

> Do you want to use the SPI peripheral to generate the pulse? T don't know why, but i don't think that is a good option, why not using Timer? An SPI clocked at the correct speed seemed to be the closest thing to what I wanted. I would only use the M...

The frequency I want would be 149.855. I can get 149.856 with a 4.032 MHz crystal, and M = 3, N = 223, P = 2. The line would be ground until I want to send a pulse, then it would be high for 50ns, or ~7.5 cycles, rounded up to 8.Looking more into it,...
