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...
STM32F413, CubeMx 5.1.0 plugin to SW4STM32, with Library STMR32Cube_FW_F4_V1.24.0. In previous versions we were able to set the transfer direction for I2S4,I2S5 half duplex channels. In the above version only transmit can be selected and the ability ...
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...
Hey,According to the datasheet, the stm32f103RB has 128K of Flash memory. If my code exceed 64k I am getting a linker error “L6406E: No space in execution regions with .ANY selector matching …�?Did I have overlooked something ?I'm working wth the Kei...
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...
I've been trying to use watchpoints to catch a possible bad write.I tried with Atollic TrueSTUDIO, but it doesn't seen to catch anything.Then I tried code, but haven't got it to catch anything either. I'd prefer the code, because GDB doesn't support ...
