I'm using a STM32L151RBT6 and trying to debug with a STLink V3.The debugger loses connection when I encounter the line:PWR_VoltageScalingConfig(PWR_VoltageScaling_Range3); Specifically, when it changes the PWR-CR Bits 12:11 (VOS). I have no issue cha...
Hello, I've just received my custom PCB with an STM32H743VIT6 MCU. It has a Samsung eMMC connected to the SDMMC1 interface (MMC 8 Bits Wide Bus) : (I'll link the eMMC datasheet below.) I'm encountering some issues while initializing the device with ...
Hi ST team, Today I have an issue in my hardware.I flash a software via STLink in debug mode succesfully. When I start the program, the console shows that "cannot read register..." or something like that :( I cannot remember.After that, STLink cannot...
I have a 12V GPIO high logic input on my board. Should I convert it to a 5V logic level or a 3.3V logic level? Previously, I have implemented 12V to 5V logic level conversion and already have components for this conversion in my inventory. If feasibl...
Dear STM team,do you consider to add "Programmable IO" (PIO, as in RP2350) or FlexIO (as in NXP MCUs) to your chips?It would be really cool: often I need interfaces on MCU which are not available as a peripheral devices, such as: MDIO (Master), JTAG ...
Hello,I've a short question - is RSS preflashed on eval boards or it is only flashed when specific part number is ordered?
hi all,we're using SW4STM32 on a project that uses CubeMX-generated code with FreeRTOS. Our own application is a mix of C and C++. We soon found that malloc/free (used behind the scenes by C++) don't play nice in the multi-threaded environment.Dav...
I'm taking my first steps as an embedded engineer, especially in STM32. I've been looking for a specialization that will give me more experience, in addition to the 35 years I have in IT (Client/Server) and about 10 in embedded systems.I'm currently...
when I am using frequency 266mhz after that I am sending the string Hello world in 0XC000000 0 but in address, 0xC0000080 appears again, can you help me with the case?thanks
i have written a driver code to run 4 wire resistive touch panel. I use only 1 adc and change its adc channel during runtime. Like i set X+ and Y+ as output high by default and X- and Y- set as low by default and set X- and y- pull down to make ADC r...
