I've been furiously googling for days and I can only find random libraries that people have written and most have been abandoned or are just so complex I cant get it working.All I want to do is to log a line of data to a file on an SD card with the f...
Hi, Expert,I have STM32F407-Discovery and I'd like to use CMSIS DSP Library for audio processing.When I checked the library version which is released, it looks 5.5.4.So, I downloaded latest CMSIS DSP Library and build it for cortex-m4 atchitecture,Be...
These are obviously leftovers from text which was in description of whatever mcu famiy the original source of this timer was (ST9 family?).This of course goes across all timer chapters within this RM, and across several RMs.JW
I need to count over 1G with a 16-bit timer, measurement accuracy is very important to me. I had to do it using a single timer, do you have any suggestions? I am using stm32f0 ant timer1Thank you
Hello, We are interested in developing a product with this MCU but we are not sure when it will be available. Can you help me with some information? We are really early in the dev. cycle and we are not going to "mass produce"(hundreds of units or tho...

I want to use the adc 15bit resolution.I don't understand why right shift and oversampling ratio are at the same time.1. what is difference12bit + 4bit right shift + oversampling ratio 128xand12bit + oversampling ratio 8x?2. What are the functions ...
I have directly connected the Tx of board to Rx of my computer and Rx of board to Tx of computer through the TTL to USB converter. I also checked the Tx and Rx of the board on DSO but was not able to see any data.
If I execute all OSPI commands with either DataMode set to HAL_OSPI_DATA_1_LINE or set to HAL_OSPI_DATA_4_LINES then everything behaves as expected. If I first execute a command with DataMode set to HAL_OSPI_DATA_1_LINE, then the Data[3]/HOLD line re...
I am benchmarking Stm32h7 processor on floating point operations and using CYCCNT to measure the performance difference .I placed my function in ITCM-RAM. which is just a function that does double math multiplication 10,000 times, the 4 variables use...
