When using JT-LINK to simulate and debug the program, after just a few minutes of debugging, a prompt appears that CORTEX-M cannot be found. What is the reason? The code has been debugged for a long t...
What is Stellaris? How come I have never heard of it? Can someone tell me about it? I am offering a reward of 5 ChipCoins. [[i] This post was last edited by Tiandiyigusha on 2010-1-7 16:30 [/i]]...
The device I use is DM6437. When I import only 2048 points of data from the outside, the result is correct after calling the library function "DSP_fft32x32". But when I import 21000 data, I only take ...

How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
