STM32 MCUs Products

Someone have info, project or something to help about EPD display's. I hate the use of ARDUINO IDE, I'm an old man that want to understand the code, I don't like the ARDUINO "magic", because it use a lot of space and is very difficult to optimize

How to receive unknown byte of data in stm32h743 series for modbus?

Hi ,I want to use my controller as a modbus slave. there is interrupt call back function which receive predefine data.but the modbus function like 15,16 have 10 to 11 byte of data and other function has 8 byte ,how to receive that thanking you

STM32F7 LPSDR SDRAM initialization

Hi! I'm writing to ask help about LPSDR SDRAM configuration on STM32F7.Currently I have a board with a normal SDRAM that is working fine. The design is based on the STM32F769I-DISCOVERY and it uses the MT48LC4M32B2 Micron SDRAM.The configuration is t...

I'm getting debugging Error "undefined debug reason 8 - target needs reset" with ST-Link V2, BluePill (STM32F103) & STM32CubeIDE, debugger config. is "ST-Link OpenOCD", Although STM32Programmer download & run with same ST-Link V2 without any problem....

Why can't I declare char? [SOLVED]

I am using STM32 Cube IDE with NUCLEO-L4P5ZGbelow is my codevoid function (int dir, int runtime){ int Run=1; int bytes_per_reading_gyro = 72; int bytes_per_reading_echo = 29; char gyro_reading[bytes_per_reading_gyro];; int echo_reading[bytes_per_rea...

Can the minimum voltage at inverting or non-inverting input pin of on-chip comparator of STM32-Nucleo G474RE be negative like the other IO pins have minimum value of Vss-0.3V?

Hi, I going to use on-chip comparator of STM32-Nucleo board G474RE in my application, the sensed voltage could go negative, the general operating conditions table (page 84) in the datasheet (Datasheet - STM32G474xB STM32G474xC STM32G474xE - Arm® Co...

STM32L151 ADC in scan mode

Hi,I'm trying to use the ADC1 of the STM32L151CBT6A in scan mode for 14 channels (with interrupt) . Depending on ADC clock and SamplingTime configuration I got only a channel on 2. If I put sampling time lower than 96 cylces (for prescaler 4) I have ...
