Posted on November 16, 2017 at 20:16Hello,I have made my custom boards inspired from nucleo board l073 but i cannot reach the same power specifications as the nucleo board. Indeed, with the same firmware, on the nucleo board, i consume 3uA whereas o...
Posted on November 16, 2017 at 16:54Dear community,my setup is build on top of stm32f439 and ADS131e4 ADC connected through spi.The adc is set in continuous mode, so it fires an impulse on a pin (DRDY) as soon as a new sample is ready.The sample con...
Posted on November 15, 2017 at 19:54I am using STM32F042F6 uC. I am not sure why this HAL_PWR_EnterSTANDBYMode() does not put the uC to sleep mode. But the odd thing is in certain condition, it does go the Standby mode, but in some other boards, t...
Posted on November 15, 2017 at 17:13 Hey. I have a board with the smallest STM32F100, with 4K RAM and 16K flash. It has only DMA1. I am using CH3 for circular DAC output already. So, for the only SPI(1) on that MCU, the DMA map in the refm...
Posted on November 15, 2017 at 17:03I'm trying tu use the Acoustic Echo cancellation library from the STM32CubeFunctionPack_SMARTMIC1_V1.0.0 package. However, all the library functions return the ACOUSTIC_LOCK_ERROR error. What am I missing?I'm usin...
Posted on November 16, 2017 at 16:09 Hello, I'm tring to read and write data from a SPI Flash Memory M25P40 with an STM32F103VDT As first try, I started to read the flash memory serial number. I used Cube32Mx to generate the initializati...
Posted on November 16, 2017 at 10:23I am trying to jump to flash loader from user application. I am using a custom board based on the STM32L476. Premising that the standard procedure 'Hw Reset + Boot0 pin setup' works flawlessly by using the example...
Posted on November 16, 2017 at 04:03I'm trying to learn to use the LL libraries available from CubeMX. I've had reasonable success using the HAL libraries in the past. Specifically, I'm trying to get TIM14 to interrupt on a regular basis and blink...
Posted on November 16, 2017 at 15:09 Hello, I am trying to sample analog inputs connected to ADC3 (STM32H7) at 4K sampling rate. For this, i have configured ADC3 to be triggered by the rising edge of LPTIM2 output signal. if (HAL_ADCEx_Cali...
Posted on November 16, 2017 at 11:32Hi !I'm working on a STM32L031 project, and I need to read 10 digital 0V-3v3 Inputs.Everything works fine if i'm reading 5 inputs (PA3, PA4, PA5, PA6, PA7). It is also working if I'm reading 5 other inputs (PB3, P...
