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 ...
I have a project that I'm compiling for the STM32U585QI, which has a dual bank architecture with two 1MB banks. My project has gotten large enough that it's going to spill over into the second memory bank. Are there any issues with running code tha...
Hi guys! I am a newbie in the STM32 world. I am little bit curious about STM32H573xx series's TrustZone feature implementation. My question is: if I develop a firmware by enabling the TrustZone (TZEN=1) and then every time when I will write the file ...
Hello everyone,I'm using stm32f103 with bluenrg-m2 over spi on custom hardware, I can send and receive messages over ble using ST BLE mobile appication.However, I need to perform application firmware update OTA and I can't find a mobile app tool to s...
