Posted on May 31, 2017 at 15:46I am trying to send a large buffer of samples to an external DAC using SPI to create arbitrary waveforms. I have previously done this successfully for 8-bit data and have tried to adapt my code to work with a 16-bit da...
Posted on May 31, 2017 at 18:31Hello guys,I would like to discuss with you about the problem of uSD card.Normally, it's working well if the application executes from internal Flash, but when it runs on SDRAM, the uSD can not initializes with FR_DISK...
Posted on May 30, 2017 at 15:48HiThere are some MCUs from several microcontroller manufacturer that they have one or several Peripheral called Configurable Custom logic. by using this peripheral you can implement some glue logics design without need...
Posted on May 31, 2017 at 14:56Hello everyone, I have looked up this issue but I am afraid I have been unable to find a solution. I am trying to wake a stm32l151CCT6 MCU up from stop mode by way of USART1 interrupt. I have the RXNE interrupt enabled...
Posted on May 31, 2017 at 17:06Hi guys,So I'm using an STM32F1 and am trying to send data from a serial terminal (RealTerm) to USART3 via a FTDI USB-UART converter cable. I have written code to poll for data on the RX line but for some reason my USA...
Posted on February 27, 2017 at 15:10How can I create a phase-shifted pwm signal ? The frequency is fixed. The board is STM32F407 discovery board so I am not 100% sure if this is possible.If it is, how can I achieve this?#phase-shift #stm32f4-discove...
Posted on June 01, 2017 at 03:47Hi, all,I have to interface PCM highway for SLIC thru MCU.Most VoIP chipset has PCM highway interface to be connected with SLIC directly.But, I want to use general MCU, not VoIP chipset.I am glancing the SAI interface...
Posted on February 26, 2016 at 15:19Is anyone aware of a method or even the feasibility to transfer captured data from the ADC module, transferred to SRAM, then stored to non volatile memory (flash) section of the Cortex M0 Arm core without having t...
Posted on June 01, 2017 at 02:36 There is an image with some BSP examples. It is stored in code memory in ascii format like this'. __ALIGN_BEGIN const unsigned char stlogo[9174] __ALIGN_END ={0x42,0x4d,0xd6,0x23,0x00,0x00,0x00,0x00,0x00,0x00,...
Posted on May 30, 2017 at 17:44Hi,When two inputs of ADC are in differential mode, can the ADCxINN input voltage be higher than the ADCxINP input voltage?For Vref+ = 3.3V and Verf- = 0V.Is the result value = ((ADCxINP - ADCxINN)/3.3) * 2048 + 2048...
