Posted on April 25, 2014 at 11:00All, 1.) I took 128, 16-bit data points and created a sine wave: const uint16_t Sine12bit[128] = { 2047, 2447, 2831, 3185, 3498, 3750, 3939, 4056, 4095, 4056, 3939, 3750, 3495, 3185, 2831, 2447, 2047, 1647...
Posted on April 03, 2014 at 20:53All, We are using the STM32F051C8T6.I have some comments and questions below but I mainly wanted to get a thumbs up to make sure I was on the right track with some of my conclusions. Thank you for taking the time t...

Posted on March 22, 2014 at 08:23I am doing an SPI write sending out dummy data to clock in the data from my SPI flash. // Dummy data to read status register out SPI_SendData8(SPI1, 0x05); // Wait until transmit buffer is empty t...
Posted on March 20, 2014 at 22:35All, I searched the forum but I didn't see any specific answers on this. I am getting the SPI peripheral setup and tested on my STM32F05*. 1.) Starting off I have the following configuration: SPI_InitStruct.SPI_NSS ...

Thanks again for the post. ''Good grief'' - well how do you think I feel! Ha. :)
1.) To verify the frequency I went back to the following line for 200 kHz.
Period = (SystemCoreClock / 200000); //...
Posted on April 29, 2014 at 08:04 I updated the code as shown below to try and get the 16 kHz sampling rate. The numbers don't look right to me. Period = (SystemCoreClock / 768000000000 ); After execution the variable period is zero. (Period = 0)....
Posted on April 29, 2014 at 07:25Thanks for the post. Okay so if I want a 16 kHz sampling this is a period of 6.25e^-5 seconds (0.0000625 seconds). Does this look correct?Period = (SystemCoreClock / 768000000000); // 16 kHz timing? 48,000,000 / 76...
Posted on April 05, 2014 at 18:26Thank you for your comments on the internal FIFO, DMA and interrupts. I am going to move forward with how I have things setup now because the timings seem sufficient. Thank you. -Mike
