Resolved! high temperature rugged MCUs? (250º)
Anyone has experience with this, does ST have anything that works beyond 105ºC?I saw cheap non Flash based 8bit mcus (Z86C04/C08) that go up to 125º-150ºAlso (TK68HC811E2) up to 175ºCI also found an article recommending chips worth 800€/piece555 chip...

Software Reset Only Occurs Once
I am using the STM32H753VIHX. I am using NVIC_SystemReset() to trigger a system reset under fault conditions. This only works once though. I am line by line debugging my code and when I flash the code to the controller and step to my test fault it su...
How to flash firmware to STM32 by STM32 with SWD?
I want to make A project that can flash firmware to STM32 by another STM32.(not Act as ST-Link, Ack as standalone Writer like CYCLONE writer)but I do not know what I should know to make the flash writter with SWD.If you have any examples or any exper...

Resolved! Want to store data in SRAM D2 domain, what is missing to avoid Hard fault?
Instead of using DTCMRAM or SRAM D1 domain via AXI, I set up the linker file to use D2.In system_stm32h7xx.c I added the lines: /* Change the switch matrix read issuing capability to 1 for the AXI D2 target (Target 2 and INI2) */ *((__IO uint32_t*...
Storage time limitation for MCU STM32F051C4T6
Hello.As the MCU is very difficult to purchase this moment, we have a stock with about 2000pcs for STM32F051C4T6, however it was manufactured in 2013. It was 8 years in the warehouse, can we use it for mass production if the soldering process is not ...
