Wondering what are example cases where low-power STM models should be preferred, and what would be the trafe-off in terms of features and performance.To help me better understand by using specific case, would be happy if I could get 2-3 examples, cle...

We have an application already running properly on STM32F411 which runs at 100mhz.When running it on STM32F405 which runs at 168mhz, there are issues e.g., COM port connection to PC etc.Seems this is the difference between 100mhz and 168mhz. See http...

Hello,I am looking for a document or online resource that lists the available functions and provides information on their functionality, inputs and outputs.For example, if searching for HAL I2C functions, then can use this:http://www.disca.upv.es/ape...

Hi,We need to transfer big amount of data from an STM32F76x connected to a PC. The expected transfer rate of data is 100Mbit/sec (100 mega bit per second). Few basic questionsis it possible to transfer in such rates?can\should it be done over LWIP?ca...

Posted on May 04, 2018 at 15:24We are using STM32-767ZI and copying a small array into a memory area which is mapped to an external FPGA.Looking for how to make the copy in a single bulk operation.The options are:1. with a loop: while(i < des...

Thanks Nikita. Very clear and helpful.

thanks. the "low frequencies" hinted to more search and found this discussion: https://www.researchgate.net/post/What-are-the-pros-and-cons-of-running-a-microcontroller-at-low-and-high-frequencycould you please clarify more about the backup SRAM? is ...

sounds good. will start reading section 6.2 (Clocks) in en.DM00031020.pdf and then do the trial-and-error with STCubeMX and evaluate the differences.

@S.Ma @Piranha @Community member folks, many thanks for the support. I can clearly see I'm missing some basic knowledge for understanding all the details (not experienced with MCUs). Terms like RCC, PLL, clock tree, MSI, Bus clock, DBGMCU, etc tha...

The application is Betaflight Flight Controller (https://github.com/betaflight/betaflight). It runs well on F411 at 100mhz, and also on STM32F303 running at 72 MHz. So the baseline is well tested.When trying to run it on STM32F405 running at 168mhz, ...
