STM32L072CZTxPVD is configured to trigger INT16 and wake up the MCU.It is working with the MCU in Sleep mode.However, when the MCU is in Stop mode the interrupt does not trigger.After reading RM0376 I am unsure if PVD is supposed to work in Stop mode...
Hello everyone! I was wondering what might go wrong with I2S DMA configured in normal mode for audio streaming with double-buffering technique. I'm not talking about circular buffer here (ping-pong) where a single buffer is used in halves in HC and T...
I cannot find this information in the NUCLEO-64 ref. manual. Do NUCLEO-64 boards generate a 5V UART TX-signal with an external 5V power supply (E5V pin)? Thank you.
Trying to answer https://community.st.com/s/question/0D53W00002HBKtaSAH/stm32l452-lse-pc13-errata I realized it's a widespread erratum which recently appeared in most older STM32 errata.I understand that issues like these may surface after years. OTO...
I am using a Flintec TR2 board, and I want to communicate with it via my STM32 L496zg Nucleo Board. It uses I2C repeated start condition to communicate. Most of the codes I found online suggest using HAL_I2C_Mem_Read/Write functions but the user manu...
Hello,I am using STM32F745VEHx. I would like to disable the software independent watchdog before microcontroller goes into Sleep low power mode and then re-enable it once microcontroller comes out of Sleep. I can find literature which suggests this c...
The problemI am to compare the phase shift between two sinewaves from an external source (I used a function generator in this case). I am running the STM32F303K8 at 64MHz, and this clock goes directly to the ADC and Timers 1 and 2 as well with a pres...
Stm32f334 i2c works in slave mode , select i2c kernel clock 72mhz. datasheet says it's i2c fast-mode+ support up to 1mhz, but I found that it can be accessed stably by a master with scl at 2.5mhz. Is it ok to use a master scl speed faster than...
Bonjour,Je travaille sur une carte qui a été créée avec un STM32L452. Au moment de la brancher au pc, le pc n'a pas reconnu la carte. En effet, une erreur de conception à eu lieu sur le STM32. Sur la broche PH3/BOOT0 il n'y a pas de resistance liée à...
I have a application with STM32F429ZI and SD card withour RTOS.I have a llong time for write in a SD card.The rcvr_datablock routine is loong about 3 ms between set and reset LED !!!It is possible to reduce this time using rot_rdq without use a RTOS ...
