STM32 MCUs Products

I'm Working on CAN protocol. Its worked good in loopback mode . but while executing in normal mode it will show dominant bit error.

using STM32f103c8t6 and transceiver MCP2551. This transceiver working well in with other controllers.

STM32L4 support eMMC

Posted on June 13, 2018 at 15:57How to make my STM32L4 to support eMMC device ? I run the code cube_FW_L4_V1.12.0 on my board then it failed on the cmd55 at SD_PowerON stage.The eMMC chip is the 'KingSton  eMMC04G-M627 eMMC' 4GB. Any idea . Thanks 

Standby power consumption is too high, touching the UART pins with hand fixes it?

Hi all,Just looking for some thoughts to what might be happening here.I'm using an STM32L052C8T microcontroller in a low power application. I send the MCU to sleep in standby mode however the MCU power consumption is too high at about 615uA. It may s...

STSPIN32F0 AD Converter problem: There is a difference between different silicon variant.

I use STSPIN32F0 since over 2 years. In the last assembly I have a problem with wrong AD values. So SW is in the older and in the newer hardware equal. The problem is so strange.Attached is the schematic of Keypad Input which is connected to PB1 (AD9...

Which is the RMII output idle level of the STM32F4 MAC ?

Figure 365. "Frame transmission in MMI and RMII modes" of RM0090 shows the low levels on the RMII outputs in the idle state. Is this guaranteed?

Custom In Application Programming via USB Device Firmware Upgrade using DFuse Tool.

I have a requirement to design IAP bootloader for STM32F427 based custom board. Can we design such an IAP bootloader which will communicate to DFuse tool using the same windows drivers provided by the ST along with DFuse Software package. I have trie...

Is it possible to use this external SDRAM to store program variables instead of using MCU onboard RAM using the Flexible memory controller (FMC)?

Hi.I am using the STM32746G Discovery Board and running the STemWin which uses the external SDRAM [Part No.: MT48LC4M32B2B5-6A, Manufacturer: MICRON] to buffer the LCD rendering. Is it possible to use this external SDRAM to store program variables in...

Composite Devices Support

Hi there,i wondered if it's possible to support more than two composite device classes. I am using stm32f407ig and in the reference it says there is a control endpoint 0 and it supports 3 IN/OUT Endpoints. So it must be possible to implement CDC+HID+...
