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...
I would like to do this to control LED strips, however, I have a problem because no matter how hard I try using the HAL_I2C_Master, it doesn't work.
Device STM32F373CCT648 pin We currently using 2 single ended 16 bit SADC inputs one on SADC1 PE9 and one on SADC2 PB2.We interleave the two 50KHz single channels using a 10uS delay between them. This uses DMA SADC transfer an interleaves the signal t...
It doesn't work even when I manually do the build just before launching.It doesn't work properly when checked either, because the build process is repeated each time although it's completely redundant, since the executable file is built and there are...
Hello everybody! Sorry, I am a pianist and know very little about engineering, so I most probably will use a naïve terminology, please bear with me.The thing is I use built-in 12-bit DAC in order to generate a simple sine wave. The frequency is a bou...
