Hysteresis in analog watchdog STM32L052 operation when monitoring value are changed near thresholds.

Hi, everyone.I had used analog watchdog in STM32L052 MCU to monitor supply voltage of device for determinate when it's value will be less then low threshold level (LT in ADC_TR). High threshold I tunned to maximum value (4095).If voltage is between t...

Linker script: one function in different regions

Hello everyone.I am using ARM Compiler 6 (6.14) in the Keil uVision IDE.Now I am developing a bootloader for STM32F0. There is little RAM.The specificity of the bootloader is such that when working with Flash (erase/write operations take ~50ms) there...

I2C Bit-Banging on STM32F103

Hello,I cannot use the I2C bus pins to do I2C. That is, I can't use I2C1 or I2C2 or any of the alternate pins. I need to use PB5 as SDA and PB4 as SCK. I haven't found a way to do this in cubeMX, so I am wondering if I can bit-bang I2C on those pins....

Problem with buffer_size_send parameter using multiple SPI block

Hi everyone, I'm having problems using several SPI blocks for different data length transmission via SPI with a STM32F303 MCU. I've realized that when I try to send multiple messages with different data length (using different SPI blocks) the data bu...

How to check the working condition of the CAN Transceiver?

Recently I bought a CAN Transceiver(SN65HVD230 CAN Board Network Transceiver Evaluation Development Module) to convert CAN_RX, CAN_RX signals into CAN_H, CAN_L from a STM32L476RG Nucleo board. How can I check this Transceiver, whether it is working o...

How to connect STM32F469 discovery kit to Silabs thunderboard 2 through USB ?

Hello, We're trying to connect an STM32F469 discovery kit and a Silabs thunderboard 2 through USB, in order to send data between the ST kit and a BLE device using Thunderboard 2.There are two accessible UARTs on STM32F469 dev kit, UART3 which is also...

I have to Initialize and Use the Timers in Existing Demo Code in STMcubeIDE .Can any one tell me how to configure in STMcubeIDE on Existing code ??

STM32F103C8 internal Temp sensor on which channel? ADCx_IN16 or ADC1_IN18

Hireading the ref manual of the STM32F103C8, it says in chapter 11.10 that the temp sensor is internally connected to ADCx_IN16. In figure 39, it says that the temp sensor is connected to ADC1_IN18.I reckon that this is a simple typo, or do I miss an...

STM32L452 DMA + SDIO Overrun Issue

Hi Guys,I'm currently using an STM32L452 device and i'm having some problems with the SDIO when using it with DMA.I have configured DMA and SDIO usign the file generated from STM32Cube tool.When I try to read the SD card without using DMA , everythin...
