Resolved! I2C Communication problem with STM32F103C8 Blue Pill Board.
I am using STM32F103C8 Blue Pill Board. I am trying to communicate with ATH20 Temperature & Humidity sensor from past One week. Configured STM32F103 Blue Pill - System Clock As (8mHz * PLL8 )= 64mHz and APB1 as 32mHz.I have Trouble wit START bit, Whe...
How to exactly reset Timer
In my project, I have to count exact time and I am using very sensitive external oscilator. I configure it as a external timer. I have a certain number of overflow counts and waste values for my count, when it reaches the waste value, I create a capt...
Resolved! Where is ADCREF voltage set?
I use ADC 12 bit in STM32L03 and cannot find where CubeIDE defines which reference voltage the ADC should have. ADC_Init() is auto-generated. Is it the default used and what voltage is it?The processor is fed with 3.3V and has VDDA connected to that ...
Resolved! Timer interrupt not working in STM32G030x
We were using TIM16 to count and monitor if a button is pressed for more than 2 seconds. If pressed for more than 2 seconds, an interrupt will be generated and a flag will be set. This was successfully implemented when used as shown below:void HAL_TI...
STM32H7 Series: Shutdown/Low Power Mode High-Level Question
Hello,I am working with the STM32H7B3IIT6 MCU and it is controlling many features (CANbus, BLE, LCD Display, push buttons, etc.). One feature we're going to have on our system, naturally, is a simple on/off button that powers the overall system on an...
After I write to flash memory I cannot do it again upon reflashing entire program onto chip, how to avoid this?
I have an STM32F407 board and have worked out how to flash a certain flash-sector as well as erasing it. My problem is that whenever I have written to flash, and I reboot my board, I cannot flash again until I reflash the entire programme from STM32C...
How to correctly set the sampling frequency of the PWM for DMA ?
I am trying to build a guitar pedal using the nucleo-64 F446RE. And I'm trying to configure my CODEC using DMA. Furthermore, figure 1 below shows my CODEC output, the green sine wave (500Hz/1Vpp) is the input and the yellow sine wave is the output. N...

What is the maximum pixel clock for LCD-TFT controller in STM32H723ZGT6?
Hello, i would want to know the maximum pixel clock for TFT in STM32H723ZGT6. I have been looking at the AN4861 application note and tables 10 to 15 show the maximum pixel clock speeds for each family and configuration of pixel depth and ram memory. ...
