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...
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 ...
Resolved! STM32F410 Bat voltage measurement consumption
Hi everyone,I was just wondering if measuring VBat in continuous will drain the battery faster ? And how fast ?Unfortunately, I don't have tools that should be able to measure such a low current.I use the STM32F410CB in my project. I use the adc1 (th...
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 ...

Hi Team,How to transfer huge data through UART interface , is it any method or procedure to achieve. Brief description: Quectel module is been used, data of 80kb transported from AWS server to Quectel module.We need to identify the fastest and effici...
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...
