Hi,I'm using the STM32F411RE device to decode MP3 audio files, i'm sending the decoded data to a MAX98357A amplifier via I2S and DMA, when the SCK signal is removed from the amplifier there's a DC offset at it's output which is causing a distorted au...
Hello community, I have a little doubt. Are all the GND pins internally connected inside the microcontroller? Is the analog reference (AVSS) internally connected with the digital one (VSS)? If it not, how is the isolation between them?I don't know wh...
Per STM32F405/7 and per datasheet DocID022152 Rev 8 (stm32f4xx) ... are the values referred to in datasheet as "Temperature sensor calibration values", at addresses 0x1FFF 7A2C & 0x1FFF 7A2E (see section 5.3.22), actual factory-calibration results th...
I changed linker to use all of these three memories in domain D2. Problem is next :When i put for example uint32_t tempArray[4] = {0x2B7E1516 ,0x28AED2A6 ,0xABF71588 ,0x09CF4F3C} __attribute__((section(".sram1")));this line in my code, when MCU is in...
Hi,I want to do SPI communication between STM32F407VG board and Eval-STPM34 metrology board , i am trying to read just a register of the Eval-STPM34 but i always fail , i used these pins to ensure the SPI communication :STM32 -----> EVAL-STPM34MOSI--...
Hi,i want to ensure SPI communication between STM32F407VG as master and STM32F429i as slave , i loaded the program of the master to the first board then i loaded the program of the slave to the second board , and then i plugged the two usb wire to th...
Hello all,We have Nucleo-L011K4 board, it was interfaced with a sensor via I2C, I want to see how much power only the microcontroller is consuming for different clocks with I2C is running.I have used XLPM01_Power_shield board measure the power consum...
Hi ,I have been testing STPM33 power offset calibration.It seems not working as per the Calibration application note.The document says we need to write offset values to offset register in the sensor and then the read power will be substracting that o...
I'm building SPI slave based on STM32F750V8T6 MCU and I'm having problem loosing sync between master and slave. When I run test that is sending sync bytes, slave receive data from master, sync again and slave is returning data after some time master ...
Hi, I'm using STM32L0 series and working on UART to communicate with other module and I had chosen the polling method because i know the device max response time and exact data what i'm going to receive. I was running my application for testing and i...
