STM32 MCUs Products

Hi I am going to get sensor data from the BMI160 through SPI with ST32L432KC. I appreciate it if anyone can help me with how I can configure the SPI. Thanks

Auto Delay ADC STM32F3

Hello Community,I'm currently programming a framework for the STM32F3 ADC. However I ran into a problem. I want my ADC to run continuously. Moreover I expect "long" delays between reading the channels. I thought, this is no problem, since the ADC has...

STM32 - support for ITM/DWT

Hello,I am interested to use the ITM/DWT over SWD to output trace data and observe structural coverage during test. My debug tool says that the microcontroller must support ITM and DWT. I am using STM32L433CC (LQFP48 package). In RM0394 section 46...

How to properly re-enable UART after an overrun failure?

There is a scenario in my application where a UART FIFO overrun can occur. The application can handle dropped packets, so this is not a concern. The issue is that when an overrun occurs, the UART stops interrupting when new bytes fill the HW FIFO. I...

How to handle the Usart receive with unknow Data length.

i am try to interface the STM32F103C8T6 with GSM & usb to Serial converter (Multi USART). But in GSM AT Comment Response Data Length is Different for Each & every time. I don't know how to handle the UART Receive with unknown data length Pleas...

HAL_ADC_PollForConversion vs HAL_ADC_GetValue

Hello, I see ADC examples that use the following functions:1.HAL_ADC_PollForConversion.2.HAL_ADC_GetValue.Questions:a. What's the difference between both functions ?b. In my application I simply want to get the ADC voltage when a user sends a command...

SPI slave - different behavior without debugger

Hi,I am using STM32L051R8T6 and i have implemented an SPI slave using the HAL libraries. I am using DMA. the master is an FPGA. SPI clock is ~2Mhz. The FPGA initiate 2 read commands for each read from the MCU - 1 for it to prepare the data and 1 to r...

Atollic problem to debug

Hello all,I have been using Atollic and the STM32 for a long time.I just created a new board with an STM32L151CB MCU.When I try to go into debug mode with Atollic, if the MCU is blank, I get this message.If I flash the MCU with STlinkUtility, and the...
