Posted on April 21, 2014 at 07:55Hi,I am using STM32F303 to generate 2 sine-waves on DAC_Channel1 and DAC_Channel2.I use one lookup table to generate the sine-wave. And I succeded to generate sine-waves on both channels, but the generated signals h...

Posted on April 26, 2014 at 20:44Is anybody willing to explain ''The TIMxCLK frequency is set to SystemCoreClock/4 (Hz). The Prescaler is 0, so the counter clock is SystemCoreClock/2 (Hz). '' Is TIMxCLK not the same as counter clock? Thanks, Jonath...
Posted on April 25, 2014 at 17:13Hello everyoneI had this question in the back of my mind for some time now, i have a vague answer, but that is not what engineers are about -precision , right !? :)The question pertains to any MCU or DSP, how do you...
Posted on April 25, 2014 at 03:35Greetings all,I'm trying to use STM32CubeMX to build a configuration for the EMCraft STM32F4 SOM. In trying to get the SDRAM functional and I believe I have the settings correct; however it looks like the generated c...
Posted on April 25, 2014 at 15:16Hi, all, I use STM32F103VCT6 and VirtualComport_Loopback project for usb communication, the usb part works fine. Now, I try to output the MCO at PA8, failed.void MCO_Config(void){ GPIO_InitTypeDef is; RCC_APB...
Posted on April 24, 2014 at 15:59 Hi all, Hoping to get a second pair of eyes on this code. I'm trying to capture large amounts of data from USART1 using DMA on an F30x series MCU. So far no luck - feels like I'm looking past an ob...
Posted on April 25, 2014 at 22:00I am using an STM32F050G6 processor and using DMA to read 4 AD channels. I am a little confused on how to control the order of the DMA reads of the ADC.Currently my code is set up to read channels 6,7,8,9 (PA6,7 PB0...
