Here in the below image from the Cube MX it suggests that, SET all the free pins as analog (to optimize the power consumption). How does it help. Also is it applicable to all the controller families?

Hi, i have an application where i have to read data and store in a buffer, now the buffer length depends on the data_len byte once received from the slave. Than is it wise to use Malloc/Calloc functions? Basically is the dynamic memory allocation sup...

Hi, I have been using PWM with DMA in one project with register-level programming, there i could find the RAM usage was around 28% and the ROM usage was hardly 0.5%. The similar application project when i tried with using HAL API's, I found the RAM u...

Hi there, i am using STM32F401RE development board and using PWM generation using DMA. I am following register level programming approach and here the issue lies in the DMA settings. Like if I set my PSIZE and MSIZE to 32-bit long and also if my data...

Hi everyone, i have a requirement where i need to work on the basic PID operations. For that i want to know how i can perform integration and differential equations using STM32F401RE controller. I had a glance through the "math.h" library but now sur...

Great i came to know about stream buffers, but the thing is i am not using RTOS for my simple RS232 data read application but here the data length is depending on 1 byte received from the slave device which indicates how much data the packet is holdi...

Hey, just looking for some heads up, where exactly can i find my memory map file?

Yep, i am using large DMA buffer size, roughly 226 * 3 (bytes). Also as you said register level uses less memory compared to HAL, that is true in case of ROM, but just not in case of RAM. So what should be the solution for having larger dynamic buffe...

Okay that i got it but the thing is what if i use byte as the MSIZE and PSIZE, it should work right?

DJ1 · 2023-09-27

Yeah okay, actually my concern is do we have any function in "math.h" which can help us do that or not. I went through it and found many mathematical operations are possible.
