Resolved! I2S STM32 Sampling frequency different from what reference manual states, why?
Hi Guys, in the reference sheet of the STM32H753ZI Pg. 2212 it says "FWS is the audio samplingfrequency."There's a programing example provided at Pg. 2232 that says Sampling Freq = 48kHz.I tried this exact configuration, the MCLK, FWS, and SCLK are a...
INTERFACING STM32 AND ARDUINO UNO V3 SHIELD
Hi Team I am trying to interface ARDUINO ans STM32H7B31 I have both boards and i have studied the document that says the arduino connections CN10 CN11 CN19 CN20I hope it need and interface/shield to to connect as both the boards have the female conn...
HAL_QSPI_TxCpltCallback function is not being called for HAL_QSPI_Transmit function
But yet it is called for HAL_QSPI_Transmit_DMA function? Do I need to configure the autopolling with the QSPI_AutoPollingTypeDef structure for the callback to be called with the HAL_QSPI_Transmit function?
Why does my LSCO output for my LSE have a delay in matching my LSE input.
I am developing on a STM32L4 product and was having issues with the CSS shutting down my LSE signal. I found this problem in the errata and turned the CSS off, but it forced me to look closer at the signal my LSE crystal was providing (using the LSCO...
Resolved! Find a simple solution to identify one of two boards I am using
I am a student who is currently doing his bachelor thesis. My job is to control two microcontrollers (Nucleo-STM32F411RE) via Bluetooth (X-Nucleo-BNRG2A1) in order to transfer parameter values for a system. The idea now is to use the same program on ...
Is DMA peripheral to peripheral data transfer possible in the 32L476rg MCU ?
HelloI am currently working on a project that requires pushing data directly from a uart rx pin directly to an SPI device (an external SRAM) tx pin One way to do it, is by using DMA , unfortunately most Stm32 MCUs do not offer a peripheral to periph...
Flashing STM32L412CB without using STM32CubeProgrammer.
Dear STMicroelectronicsI am an employee of the TaiPit company, we are engaged in the production of electricity meters. In modems for electricity meters, we use STM32L412CB microcontrollers and additionally some modules. At the moment, the task i...
What happens when GPIO is sourcing more mA than allowed?
My STM32F746 can source 25 mA per pin, but only 120 mA in total.What happens if we exceed that amount? Will there be a brown out, will the STM32 reset, or will the STM32 get damaged?
