Writing Blocks of ADC DMA Conversions to SD Card on the STM32F7 Discovery Board (ADC + Timer + DMA + SDMMC)

I'm trying to write blocks of ADC Conversions using DMA from the STM32F46 Dsicovery board and I'm having issues writing to the SD card when HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) is called. I'm running a 500KHz timer to trigger my ADC and ...

Resolved! pwm with asymmetric dead-time

I am looking into the possibility of using a stm32 microcontroller (probably stm32f030) to directly* control the power transistors in a switch-mode power supply, in order to generate a high-power waveform.My current thinking has a PMOS switch transis...
