What is EXTIT? (and are there EXTI enable bits for real?)

Can't post screenshots.RM0401 rev3 ('F410), RCC_APB2ENR contains EXTIEN. There is no such bit in any other STM32, EXTI is unconditionally enabled everywhere else. There is no respective reset bit in RCC_APB2RSTR. Is this bit real?in the same RM0401 r...

''unknown device'' error in ST Link Utility

Posted on November 27, 2015 at 10:52When I try to target->connect in ST Link Utility I have an error ''unknown device'' with disco L4, disco F7 and nucleo L4. With nucleo L0, the connection is good, but I have the message ''Device family : unknown d...

SPI Clock rate limitation?

TL;DR. What are the limiting factors for incoming clock speed for an SPI peripheral operating in slave mode?I'm using the STM32U575 MCU with a few peripherals, and am clocking it down to 16MHz for SYSCLK and all related peripherals.  I'm generating a...

Custom external loader for MX25L12833F-STM32L4P5 - Error:failed to erase memory

Hi, i have made an custom external loader for MX25L12833F-STM32L4P5. STM32CubeProgrammer gives me the following errors: "Error:failed to erase memory". Some time it gives me the error: "Error: failed to download Segment[0]", "Error: failed to downloa...

I bought the STEVAL-ETH001V1 evaluation board and it does not have the firmware loaded on the MCU. I have to buy an emulator to programm the MCU, but does the NETX90 come already programmed? Is there an emulator that works for both?

Using SPI to interface to TI ADC & DAC

hi, i m a student learning STM32 for the first time, my project now is to interface stm32h7 using SPI to TI ADC TLV1570 and DAC TLV5608. Anyone has tutorial and any reading material on this to share? thanks in advance.

STM32L496GT6 battery voltage monitoring

I want to monitor battery voltage (Vbat). I use the adc function to monitor voltage on the Vbat pin, and it can't read the voltage. When I use the same function on other pins, it can read correctly. For Vbat monitoring, what are the specific configur...

LoRa example for STM32WL | un able to read from UART

I am currently working on the LoRaWAN_END_NODE example project for a stm32WL . And I want to receive external data via uart and use the LoRaWan process continually, however I am getting problems. I am unable to read from the UART the second time I ca...
