Bipolar output from stm32g4 DAC.
Hello, I want to use external audio op amp, OPA1622 of TI. As in the attached photo, this opamp works using bipolar input. So, please guide me how is that possible using the output of STM32G4 DAC. Regards.

Optimizing wake up time STM32L0.
I am trying to get an STM32L0 MCU to startup as quickly as possible. The datasheet says 5us wake up time from flash memory, but I am getting nowhere close to this. I loaded a super simple program that just toggles a GPIO and watched it on a logic ana...
Resolved! Is this a legit reason to use a global variable?
I understand the general concept of why global variables are not a great idea but I have a specific use that may make sense and I'd like to see if anyone has a better approach.I time stamp a lot of events in my applications and also calculate time in...
Feeding the next buffer to SAI DMA
Sorry if this has been answered elsewhere, but I'm not seeing it. For background, I do a lot of work with Nordic, and in their I2S implementation, you feed two buffers to the peripheral, then every time a buffer has been transmitted/received, it swi...
Multiple usart using DMA
Hi,Am working on a STM32F745VG micro controller and i want to use multiple uart using dma. Majorly facing issue at the reception side.When i try to receive data from uart 1 sometimes my uart 2 also receive the same data.Even though their handler are ...
Resolved! Example of SDMMC on STM32H757 i-EVAL Board
Hi everyone .I'm looking for a demo code to run the SD card (16gb) with FatFs on the STM32H757 i-EVAL Board.When I generate it with CubeMx the demonstration doesn't work (I didn't forget to activate the transiver)Thanks you =)
Regarding of checksum code for an adc values to avoid spaces with value
Hello,I working on the stm32f070c6t6 , i want to transmit an adc value to the LabVIEW VISA and storing the adc values in the labview array further processing . but when i continously giving the command from the USB COM port for adc value sometimes it...
Resolved! how to checksum the ADC data when it is passing to serial monitor of putty through the USB virtual COM port.
Hello ,I am working on the stm32f070c6 controller , i am reading the adc values from controller and passing to the serial monitor of USB virtual COM port, but i want to checksum the values before transmitting the adc values to the serial monitor .how...
Resolved! USART code run succesfully on F0 but it doesn't work on L0.
I am trying USART communication with using DMA. Code written with HAL library is working on STM32F0 but it doesn't work on L0. I am getting irrelevant data at terminal.Also HAL_UARTEx_RxEventCallback function can called on F0 but not on L0.Here is t...
power consumption stm32l4 in lprun mode
HiI am using stm32l496 in lprun mode but the current consumption is equal to 1.2 mA while in run mode the current consumption is equal to 3 mA while in the datasheet, the current consumption in the lprun mode is about 220 uA.how can I reduce the curr...
