HAL_I2C_Slave_Receive_IT issue ?

I had a problem using this API HAL_I2C_Slave_Receive_IT(&hi2c1, buff, 100) in case i send 20 bytes for example wich is a corrupted frame for me (i am waiting for 100 bytes) then i2c driver will stack this 20 bytes and it does not free them wich in a ...

Cannot Configure TIM3 , Timer count values are drifting ?

I'm using an STM32F401CCU6 microcontroller and am trying to generate a timer interrupt of 10 us with TIMER3.The timer is a update event timer. The formula I'm using is:Update_event = TIx_CLK/((PSC + 1)*(ARR + 1))Below, I've given my clock configurati...
