HII am using the STM32G474 MCU and ran into a problem with my code stopping execution.In my application, I have a level 0 priority interrupt that takes 1.34us to execute that occurs once every 6.66us. In the final code, I will need 3 of these runnin...

I'm using HRTIM Timer F to create two complementary outputs at TF1 and TF2 with deadtime. I'm finding conflicting examples of how to set the output configuration of the two outputs.Which of these code segments is correct? pOutputCfg.SetSource = HR...

I need to determine if the interrupts are enabled at one point of my code but I have not been able to find any reference for the STM32G474. It doesn't look like there is a PRIMASK register which is mentions in another post.I know how do enable and d...

I have developed a custom controller that uses the STM32G474RE to regulate the output voltage of two power supplies.I am now developing the code to implement a peak-current mode controller for each of the two power supplies. Is there a way that I ca...

I have reviewed the many posts from others that have not been able to jump from a bootloader the application code and nothing that I tried worked.My MCU has its 128kB of flash in two banks, one at 0x08000000 and the other at 0x08040000. When the MCU...

It is critical that when the ADC for a particular driver is sampled, an interrupt must occur as soon as possible that performs the required floating-point math to calculate the duty cycle at the next PWM pulse. The math takes a maximum of 1.4us to e...

Thank you. I understand that I can write my own UART functions and will do that. However, it also stops USB communications. The 150kHz interrupts are to regulate the current out of 3 synchronous buck converters that should get their PWM duty cycle...

With some search of some sample code, I found that when you have deadtime between TF1 and TF2, TF2 should be initialized with the SetSource and ResetSource set as follows: pOutputCfg.SetSource = HRTIM_OUTPUTSET_NONE; pOutputCfg.ResetSource = HRTI...

My concern is how to initialize the output of TF2. Does either of my examples handle that correctly?

My mistake, I was checking if the bit was set to determine if the interrupts were enabled, but the bit is cleared when the global interrupts are enabled.Thank you!David
