Can you use SPI in DMA mode interfacing with a SD card? If so is there an example code?

Can't connect using the I2C Bridge and the ISB042GUI "it's not possible to read the device mode information"

Hi, I'm having trouble with the ISB042V1 evaluation board and the I2C bridge dongle. I believe I have everything wired correctly, but I get an error message when I press the "Connect I2C Bridge" button on the GUI.I have provided 5V power to J2 as in...

How PDMS bonded to SU8 that covers microfabricated gold electrodes affect their electrochemical activity?

We microfabricated gold electrodes and coated them with SU8. However, when we bonded PDMS onto the SU8, the electrochemical activity of the electrodes dramatically decreased. Any ideas what could be the reason?

Accessing Timer OC register for DMA transfer.

Hi All,I'm using a STM32F302R8 and want to transfer timer 2 capture/compare values to memory using DMA. What source address do I use for the TIM2 OC register? I'm calling HAL_DMA_Start() to do this and need the source address of TIM2->OR.Thanks,

Pins connection SWD st-link to an external STM32F103RBT6

Hi!I'm trying to use my ST_linkV2 debugger to program an external STM32 microcontroller using SWD, is this configuration ok ?: CN4 (STLlink) Vdd----------> Vdd (stm32 MCU) SWCLK------> PA14 (SWCLK) ...
