Load Capacitors Crystals

How to prove if the selection of the load capacitors CL1 and CL2 for HSE and LSE Crystals is correct?Maybe with oscilloscope?

What is a CS32F103C8 and why do most STM32F103C8s have 128k Flash rather than the advertised 64k Flash?

Hi AllThe Arduino community's Blue Pill (based on the STM32F103C8) is known as a useful but very inexpensive development board (one can order about 10 pieces for $15, including post and packaging). Also it is common knowledge that most of the STM32F1...

I am using STVD and Cosmic Compiler and after add some #include files, the "Control + space" stop working. It doesn´t find the SPL (StdPeriph_Lib) function anymore. Hope anyone to solve this problem. Thanks

replacing STM32F103C6 with STM32F103CBT6

hi,i am new to embedded programming and i have a problem and i appreciate any help.I have a firmware which works on stm32f103c6 .We had to replace the controller with an other to get more space for the flash Rom and that was the stm32f103cbt6,they a...

Hello, I would like to update my board firmware using bootloader CAN. Could the STLINK-V3 allow me to flash my board using bootloader CAN ? otherwise, which kind of board should I use as a host PC ?

Actually I did not purchase one yet. I know I have to choose one with a bootloader CAN include like a STM32F412.Is there a GUI who allow a drag & drop to flash the board, using CAN ?I saw that STM32CubeProgrammer should be update to allow to flash th...

[Bug] Missing const in HAL_GPIO_Init

HAL_GPIO_Init should beHAL_GPIO_Init(GPIO_TypeDef *GPIOx, const GPIO_InitTypeDef *GPIO_Init);This applies to all HAL-Versions I've seen - probably all.

Flashing user code into STM32F103C8 (with USB bootloader updated) using TrueSTUDIO IDE

Hi,I'm using Blue Pill board (STM32F103C8 with USB bootloader updated - generic_boot20_pc13.bin). I'm connecting Blue Pill board directly to laptop using USB cable (i.e., without using any ST-Link V2 Programming Unit).I'm using TrueSTUDIO IDE without...

SDMMC & SDIO - why max 1 SD card only?

I'm writing an SDMMC driver for my C++ RTOS - http://distortos.org/ - and there is one thing which really puzzles me, making it hard to decide about class hierarchy. In the Reference Manual for STM32F7 (but the same is true for other chips, both for ...

I2C pcb and pull-up

Good morning, I wanted to ask a question about the I2C interface.In particular on the routing of the pcb, I have a micro STM32 that is the master for i2c bus, then there are 2 slaves on the board and a connector to allow the connect of a third.The qu...

Complementary PWM at active low.

I have generated complementary PWM signal on STM32L496ZGtx. I used TIM1CH1 and TIM1CH1N. I am using one pulse mode so that every 1 second, I generate complementary signal. However one channel starts at active HIGH and another starts at active LOW. Ho...
