Has anyone have similiar issues ? I got I2C DMA writes working nicely on table, but in real application there are disturbances which cause false start condition on the bus.This happen when I2C HAL driver has "lock" on I2C handle - so incoming interr...

Posted on August 10, 2017 at 17:44Does anyone know official documentation which provides info about sector layout and dual bank support in these devices ?I have searched the forum, but while there was mentioned that dual bank support is not present,...

I know.In few cases I already have my own drivers based on LL.Just I2C hardware is so overcomplicated that I decided to stay with standard non-interrupt code.I decided to post my question as warning - this problem started happening after testing who...

My working code is based on on such example.I basically call library function - the code is provided by STM32CubeIDE HAL_I2C_Mem_Write_DMA(hi2c, DevAddr, WriteAddr, I2C_MEMADD_SIZE_8BIT, (uint8_t*)pBuffer, *NumByteToWrite);And this - in case of distu...

I2C in DMA mode - deadlock on I2C interrupt

Why I do not get all user label defines in main.h ? I got them only for timers, but non of GPIO. Note - this is for STM32H7, dual core. None of the cores get them. Most of the pins are set as reserved for M7 core.
