STM32 MCUs Products

Does anyone know the susceptibility of STM32F4 VBATT pin to ESD surges when changing out the RTC coin cell battery, or if there is some sort of internal protection against this happening such that an ESD protection diode would not be necessary?

How to implement VC0706 camera to STM32F4?

There are plenty of codes about VC0706 camera + Arduino. I tried the sample on Arduino and it worked pretty well. But I need to make this project with STM32. Any ideas how to implement and code VC0706 with STM32?

USB Host With Multiple Vendor Specific Devices

Posted on August 28, 2014 at 22:23I'm new to USB programming, and am having some trouble getting my head around the concepts involved.  Hopefully someone can have a look at what I think I need to do to meet my goals and tell me where I'm right and w...

In the datasheet for the STM32L151 is missing the value of the sampling switch resistance R_ADC in table 55. Does anybody knows the R_ADC value?

HAL I2C always sends 0xFF as first byte when responding to master using HAL_I2C_Slave_Transmit

I have an STM32G4 using the HAL function HAL_I2C_Slave_Transmit to respond with some data when requested by a master on the I2C bus. In the image below you can see the device sends 0xFF followed by the actual data it was meant to send (the data I am ...

when getting ADC value, RMS processing is necessary needed?

Hello, I am using LO31K6 for sensoring two ADC channels by DMAWhen I wish to get trustable voltage value, Do I have to apply Root Mean Square to these ADC value?for example, < Instead directly get ADC value from DMA buffer[n] and treat as it is true ...

stm32f446re nucleo board bit band ALIAS range

I have few doubts as follows:1. Each MEMORY MAPPED ADDRESS is how many bytes wide? 1 or 4 bytes (I think it as 1 byte).2. The ST datasheet for stm446xx says the SRAM is of 128Kb size then,start and end addresss is 0x20000000 to 0x2001FFFF but, bit ba...
