STM32F446 EXTI GPIO interrupt not triggering

Hello, I’m working with an STM32F446 and have configured GPIOB pin 12 as an EXTI input. After initialization and before entering the main while loop, I call a function that blocks program execution(what I mean by blocking : I have a test that stands ...

ISSUE with STM32L051C8T6

Dear ST Team,我用usb转ttl单独对4g模块发at,回复消息是正常的,单独模拟给单片机发数据,回应的数据也没有丢字符,就是4g模块跟单片机之间通信的时候存在问题When I use a USB-to-TTL adapter to send AT commands to the 4G module alone, the responses are normal. When I simulate sending data to the microcontroller alone, th...

RM0394 SRAM2 connectivity in bus matrix

In the lower-end STM32L4, covered by RM0394, SRAM is partitioned into two parts, SRAM1 and SRAM2.SRAM2 (besides being "special" in that it has ECC and automatic erase facities), is mapped at both 0x1000'0000 and at the end of SRAM1 in the 0x200x'xxxx...

Resolved! STM32N6 I2C Logic Levels

I have an I2C device that only operates with 1.8V logic (Pins are not 3.3V tolerant) that I want to connect to the STM32N6.  I don't want to add an I2C redriver if I can avoid it.  I want to keep as many of my I/O pins on the STM32N6 powered from 3.3...
