using 32 MHz crystall with STM32L011K4

Hi,In a project I need a precise timing so I cant rely on th internal oscilator and want to use a crystal 24-32MHz with MCU. But actually I couldnt find anything about this possibility in datasheet.the sample is 32 KHz that is not good for my applica...

STM32F779BIT6 custom board SD card initialization failed.

I am using custom board with STM32F779BIT6, connected micro sd card to the controller.Every time I initialize micro SD card gives error of SDMMC_ERROR_CMD_RSP_TIMEOUT.Any solution.

Why Linker file needs to be modified to use External memory(RAM/Flash) if I can access external memory using communication modes like SPI,I2C,etc ?

I have seen many examples to use external memory as heap but for it they have modified the linker and added section of needed memory. But I am curious if I can access the external memory using standard communication interfaces like I2c, SPI, etc then...

Is there a dual core Discovery board (already)

I would like to play with a dual core STM32F

Generate a single interrupt on TIM3_IRQHandler() when CCR is reached instead of every rising pulse

Hi all.I have a motor encoder connected to TIM3 and I'm trying to generate a single interrupt once 1848 ticks have been reached. However, TIM3_IRQHandler() keeps being triggered for every rising edge of the pulse. I just want a single interrupt trigg...

L4 color space clut

I only need to display around 8 colors in rgb space and if i use L4 color space i can reduce my framebuffer to the point where i can put the entire framebuffer in internal sram. The only problem is i don't understand how to format the clut in L4.

How to take the UUID from a stmre microcontroller

Under what conditions does bxCAN fail to transmit?

Hello, I am working on a project trying to merge 2 discrete CAN buses with the STM32F746zgt6 using bxCAN with the HAL drivers. This system will take packets in on both transceivers, one on each bus, and try to output on the opposite transceiver, esse...

STM32F415 - Automatic Erase of Flash on power ON

I am using Mini-M4 module with STMF415RG MCU. Module is programmed using STLink SW interface. However when the module is put on to the mother board, the flash memory gets erased when the board is powered on. What can be the reason for this automati...
