SPI communication between 2 stm32 boards

Hi @Community member​ i want to establish communication between the F411E-Disco as a master and the F413H-Disco as slave( so the idea is to display the temperature value acquired by the PT-100 using ADC in the the F411and then sending the value throu...

What timers are free

Cube/HAL shows some nice Timers, are they free. That is are they used by for instance HAL_Delay or something else. What about the examples and their timer usage.

STM32L4 not exiting sleep mode

When trying to implement sleep mode it appears the code enters and exits sleep mode once and then gets stuck in sleep mode after and will not wake back up. I posted some code below of what I believe affects the sleep function. I want the code to slee...

Hello,DS12469 Rev 6 in Features on page 1 lists "Accurate 2.5 V or 2.048 V reference voltage buffered output" under  "Rich analog peripherals". However "Table 2. STM32L412xx family device features and peripheral counts (continued)" says "Internal vol...

How to make partition binaries for STM32F103ZC using Makefiles

I just switched from Arduino to the ST HAL library, I'm quite new to both the structure and makefiles in general. I'm using a chip that allows for multiple parts that can be used for OTA's for example. While I have made a working project that can upl...

ESP8266 is communicating serially with STM32L4 through AT commands.Now I would like to implement the MQTT protocol implementation on this?

Why SDADC could't not start

Hi everyone,I designed my custom board with stm32f373c8. SDADC runs properly when voltage reference is setted with Vref or VDDA. But when voltage reference is setted with internal 1.8 volt or internal 1.2 , sdadc could't start. It waited while loop t...
