Resolved! STM32F091 Flash erase, how long does it take busy to go active?
I'm working on a bootloader which needs to erase and program the Flash. The erase seems to be 'working' but I have a suspicion that I'm not waiting long enough for the 'Busy' bit to go active after setting the 'Start' bit. The reference manual says I...
Could not set IWDG timeout to max (~32s) for STM32G031?
I am using Nucleo-G031K board and attempt to set IWDG timeout to max value of ~32s. Got hard fault. Here is the code. Any idea? iwdg_hIwdg.Instance = IWDG; iwdg_hIwdg.Init.Prescaler = IWDG_PRESCALER_256; iwdg_hIwdg.Init.Window = IWDG_WINDOW_DISABLE;...
STM32F072RB in I2C slave mode
I am using STM as i2c slave. When other i2c master reads, first byte is always 0xFF and rest are correct data from STM with 1 byte shift so master needs to read 1 extra byte. Also I get HAL_I2C_ERROR_OVR error during that. Please suggest.
Resolved! Output of interrupt routine inconsistent between different bits?
Hi,I'm having an issue which I can't seem to resolve:I'm trying to change the output value of Pin9 (Port C) through an interrupt routine (TIM3).If I put a simple XOR statement for this pin in the interrupt routine it works as expected.However if I tr...
Multiprocessor mode with address mark detection only receives data which has '0' as MSB. After waking up (RWU=0) when the correct address is received subsequent bytes should be received normally, and not interpreted as another address?
I have configured the UART for multiprocessor communication over RS485. I can receive and transmit data correctly, but if the data contains a '1' as MSB it is interpreted as an address. Now it is clear from the documentation that this is the correct ...
