STM32L4 SPI interface to Flash Memory Winbond W25Q80DV

I am trying to interface with the Winbond W25Q80DV which is a SPI flash memory chip. I am using the STM32L476VG development board. To test the connection I am first trying to read the manufacturing ID from the chip. Using an oscilloscope I am able t...

I can't read BYTEs from the QUAD SPI using the indirect mode.

I'm using the following code to read from the QUADSPI data register. (uint8_t) * dptr;*dptr++ = QUADSPI->DR;What I get is it reads 4 BYTEs from the FIFO and only returns the lowest Byte in memory pointed to by dptr. The ref manual says you can read B...

SWDIO & SWCLK on DiscoveryVL card - can I use these as GPIO?

I have a DiscoveryVL card (STM32F100RB) and I want to use pins A13 & A14. The manual says I have to unsolder some jumpers on the back to use these as GPIO but then SWD won't be available. I have been using the ST-LINK utility program via a USB cable ...

Is there any way to expand the CAN filters on STM32 MCUs using external Hardware?

Hello,I have been looking to read almost 200 different Extended CAN Ids on any of the CAN equipped STM32 MCUs. Speed in 1Mbps on CAN. Currently, I am working with ID list mode using all 28 filters and switching between CAN Ids as required. But I am f...

Do I need to modify the linker for simple SDRAM read/write operation?

Hi,I am using the STM32F746G-Disco board with SW4STM32 IDE and I have the SDRAM working on it.Now I am trying to port this project to the STM32CUBE IDE using the integrated STM32Cube.However, when I try to read the SDRAM, I end up in the hard fault h...
