Posted on August 12, 2013 at 08:10Hello everyone, I am newbie in this forum so please forgive me for any noob questions. My application requires to save 4 double variables offline for next time usage, I think my data is too small to make us use a SD...
Posted on August 08, 2013 at 05:14 I'm sorry, that's probably quite a beaten topic :( I have continues mode ADC running on stm32f4discovery board. static void ADC_Config(void) { ADC_InitTypeDef ADC_InitStructure; ADC_CommonInitTypeDef...
Posted on August 09, 2013 at 10:42I'm using the ''arm_cfft_radix4_f32(&S, FFTData); '' function to obtain the FFT of an array and then inverse it back after some processing. I have things working, to a point, but with some odd restrictions. Firstl...
Posted on August 09, 2013 at 20:18Hello, everyone. I am currently playing around with the USART without standard peripheral lib provided by ST (using CMSIS only) and my code strangely works in one MDK project and does not work in another MDK projec...
