how to build a stm32 IOT ethernet/lwip device
Hii need to build a simple IOT motor control unit. I also need OTA update.what is the quickest way of getting started?Mongoose os? What else is there?Thx

Reading PDM data from MP34DT05-A with STM32F407 I2S
Hello, it is the first time when i have to deal with microphones and PDM interface. I just can't get correct data from the microphone, or the data is correct but i am doing something terribly wrong. I configure I2S to sample microphone with DMA. Whe...
Error: Hard Fault Detected, how do I fix?
Hello all, I am still attempting to create my project on the STM32F411RE that is capable of taking in 3 sinusoidal signals and return the frequencies + amplitudes for these signals. Thus I need to use the CMSIS-DSP pack, but this is continuously givi...
STM32F413VGT6 FLASH LOADER DEMONSTRATOR
I am developing with STM32F413.I try to download the program using USART1, but the FLSH LOADER DEMONSTRATOR recognizes it as another device. (STM8)What should I check?
Where may I find a summary of STM32-Manual used acronyms?
Many times you use UG Bit for "Unfortunately Generic" or EGR for "Emission Gas Recirculation"?A lot of explanations are hardly to understand and make no sense, because acronyms are not unique. I think there should by a glossary at the end of each doc...
STM32F4 RFID using HAL library
HiI need to use RFID with an stm32f4 controller. By using RC522 library it is not working for me can anyone tell that is there is any library available for it or is i have change anything RC522 library.
stm32f446 waking from UART in STOP mode
I am putting board into STOP mode for saving power. From the manuals the board can be woken up from STOP by EXTI interrupt. Is it possible to waking it up by UART by configuring it as EXTI interrupt on Rx pin. If yes how can I achieve this?
Resolved! Possible to continuously ADC sample only during active phase of PWM? (STM32F466RE)
I'm using an STM32F466RE to drive a motor via PWM and want to sample a current monitor via ADC during the active part of the pulse so that I can integrate the amount of power delivered to the motor. This will require the sample rate to be high enoug...
Resolved! STM32F427 I2S with DMA - noise - not audio
I don't use libraries.I got I2S working by polling. Below was my test. I had an array of 16 bit signed words for a tone of 1khz. The I2S pins from the MCU feed a an external DAC and produces a very nice tone. RCC->APB1ENR |= RCC_APB1ENR_SPI3EN...
