Dear Technical team，We are developing an IoT product using STM32H750.The application starts a task cycle to publish customer information to the cloud platform by MQTT Publish API.At the same time, we make a ping tests to target board from the PC host...
Hallo All,I am currently stuck and need your help. The following function counts the no. of 1 in a 32 bit word on an STM32F407. Why does it fail for values which have their bit 31 set? Precisely, it ignores bit 31 and in these cases is off by one. ...
Hello;I am working with STM32CubeIDE, trying to connect a Nucleo-L4R5ZI board to an ADCS chip using I2C. The method of communication is very strange, requiring: [start condition] - [controller sends two bytes] - [start condition] - [controller sends ...
CONFIGURATION:USING STM32H743XI DAC1 / DAC OP: CONFIGURATION: NORMAL BUFFERED OUTPUT MODE.PINNO: PA4 & PA5. using HAL_DAC_SetValue function to change DAC values - 0 to 3.0 V. if want to set 2.0 V, respective cnt applied using HAL_DAC_SetValue, at DAC...
Hi,I'm currently working on file transfer through the XMODEM protocol, and I want to implement the logic in STM32CubeIDE. If anyone has already implemented it, please share the source code. It would be helpful for me. Thanks
Hi,I'm able to configure LWIP with my Nucleo-F439 board so that it responds to pings as expected. I however want to be able to transport some useful information to a socket (telnet or similar) and I want to use FreeeRTOS for that. I however am unable...
Hi,I'm using STM32G070RBTx, and I use this formula from document RM0360 to compute temeperature:From page 56 of document https://www.st.com/resource/en/datasheet/stm32g070cb.pdf, I'm using:Avg_Slope = 2.5 and V30 = 0.76.The temperature converted valu...
Hi everybody, My project is reading encoder data, and then send this data to the terminal via USB connection. As transmit and receive I want to use CDC_Transmit and CDC_Receive function. But no matter what I do, I cannot see the encoder data in the...
I have initialized a project with STM32CubeIDE (the .ioc file) using the STM32F407G discovery.I want to produce on an output pin of the TIMER4 a PWM signal with a certain duty cycle, so I set in the .ioc file the various parameters and in particular ...
Hello,I am currently using Olimex's STM32 E407 board. I am using raw tcp. I enabled lwIP on CubeMX. I have been able to create a TCP server, connect the board to my computer with ethernet cable and communicate. The problems I am facing now are as bel...
