I wish to put an older (2011) IMAC computer into service to handle some STM32 development tasks. The IMAC is running the last version of MACOS published for that hardware (I believe the GPU was abandoned by Apple subsequently.) MACOS 10.13.6 is 32-bi...

I'm working on migrating a design from STM32F405 series to STM32G473 series, both LQFP100 package, both use FSMC for access to external SRAM (in multiplexed mode; I have separate address latches clocked from FMC_NADV capturing A0..A15 from D0..D15.) ...

An application will use two STM-32 MCUs - for purpose of this posting, I'll call them "outer" (it's SWDIO and SWCLK pins can be attached to a STLINK-V2 device for firmware downloading), and "inner" (it's SWDIO and SWCLK pins would be tied to two GPIO...

In datasheet for STM32G431 series and RM0440 (applicable reference), there are references to ADC12 (I'm encountering this when working on ADC converter, pin and channel assignments for an application.) There doesn't appear to be a specific definition...

Looking for English-language datasheet for STM32F400CBT6 MCU.I've attached Chinese-language datasheet (downloaded from jlcpcb.com/lcsc.com) and a link to a selection guide (https://static.stmcu.com.cn/upload/Selection_Guide.pdf) which tells me that t...

Installed both latest-version items without difficulty on MACOS 10.13.6, so wherever I saw mentions that MACOS 10.15 was minimum OS and 64-bit install was mandatory evidently was not the case.

Thanks so much for the pointers!

Returning to this topic after a long time as implementation is now necessary - I did a search yesterday on the terms "stm32 parallel display gpio". One of the initial results was this document (dated January 2016) from ST Microsystems:AN4666Applicati...

Thank you!

Thanks! I compared tables (not narrative) between it and STM32F410CBT6 datasheet (the part I'm interested in substituting with STM32F400CBT6) and didn't see any differences so far. For my purpose, I suspect so far it is a usable alternative (I don't ...

Need find old (ca 2018) STM32CubeIDE and STM32CubeProgrammer releases for MACOS 10.13.6 (32-bit)

STM32G473/4 FMC/FSMC feature, pin called FMC_NL and FMC_NADV in datasheet DS12712 rev 5

Application with two STM-32 MCU and one STLINK-V2 port (to one of the MCUs) - cascading possible?

STM32G431 and RM0440 - references to "ADC12" in documents - what is definition?

STM32F400CBT6 - looking for (english) datasheet
