Hi,I am using STM32F103C8T6 Blue pill board, STM32 CubeIDE 1.16.0, Build: 21983_20240628_1741 (UTC) on Ubuntu 22.04.5 LTS and ST Link v2 debugger. I am able to upload code, execute it and debug it via SWD.I am using CubeIDE's Pinout & configuration u...
If I call HAL_UARTEx_ReceiveToIdle_IT to receive 512 bytes, will it wait till all 512 bytes are received before calling HAL_UARTEx_RxEventCallback or could it possibly call it several times, delivering fragments of the whole packet?I'm asking because...
Hello, I am using an STM32F103CBT as an I2C slave. A memory buffer is to be transferred via the interface. Although hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE; is set, I cannot measure clock stretching and the first byte transferred is always 0...
I think the word "reproduced" should not be used in this yellow marked sentence,and the word "resolved" should replace the word "reproduced"，due to the purpose of NRST pin is to solve the most of common failures,not to reproduce them。 Am I right?
Hello everybody,I try to get canbus communication on the blue pill+ under zephyr to work. I use the canopennode sample. I got the following overlay: / { model = "STM32 Minimum Development Board (Blue)"; compatible = "stm32_min_dev_blu...
Hello,STM32F103RB microcontroller.7-bit master transmitter (see Figure 273).When I send Address then I receive AF bit of I2C_SR1 register equals "1" (Acknowledge failure). But the diagram taken from the oscilloscope shows that after the address there...
We are using STM32F105 ADC function in some of our products for temperature sensing, etc. We found that sometimes it has accuracy issue after operating for a while. We suspect that it's the power, resistor, or capacitor we used are not of good enough...
Hi all, I've been battling an I2C issue for a couple of weeks, been through so many forum posts, and have tried a number of things, now I'm looking for some help to figure out what I'm missing. Problem Description:Master I2C device triggers slave tra...
We are using STM32F105VCT micro in our product from many years.In the recent hardwares, we have seen that input logic level is changing only with 200mv change.When the input voltage to any port pin is crossing 1.5 we are seeing as logic level 1, when...
HI everybody,Using the STM32F103 series, I was able to configure a single channel with DMA and get ADC data, but I was unable to analyze any data or do any while loop calculations for the moment. I simply increased a variable to see if it was updatin...
