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...
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...
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?
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...
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.
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?
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...
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...
I am collecting a stream of ADC samples that are being integrated (added together and multiplied by the time period) at regular intervals during an ISR but was hoping there may be a way to offload this so I could just read and reset the accumulated v...
