I am using the stm32h745ziq-nucleo board . I am generating the pulse in the cm7 and I am trying ton capture the falling edge of the pulse. I am getting the falling edge capture for every falling pulse But I want to capture only the 8th falling edge o...
Resolved! Executing code from RAM problems
I'm developing application on stm32H7 and a need to execute small function from RAM. I add RamFunc derective, and describe in linker *(.RamFunc) in .data section. As a result, i certainly see, that function code moved to RAM address space. I compare ...
Howto implement I2C slave clock stretch timeout.
Hi,I like to implement a I2C slave on a STM32G081 with using stm32cubeide.Basically, it is working.Sometimes, the system communication stuck while a transaction on the STM32 I2C slave is active.How can I implement a clock stretch timeout on slave sid...
Resolved! HAL_I2C_SlaveTxCpltCallback() is called despite not all bytes are sent?
Hi,I´m using an stm32f401 and observing suspicious behaviour on the I2C slave.My issue is that I get transmit completed callback after master has read 1 byte, but I have called HAL_I2C_Slave_Seq_Transmit_IT to send 2 bytes.I´m trying to send 2 bytes ...
