Hi,I am using Tower Pro SG90 servo motor interfaced with STM32F401. Timer 2 is used for generating PWM and timer 5 is used for generating the delay. I tried multiple code changes by myself and also took help from internet, but the servo jitters a lot...
Hello everyone, I was trying to use 2 mics IMP34DT05 in stereo configuration with MCU.I wanted to capture signals from both the mics as well as i want to use single mic also. Please guide how can be this configuration done in schematic and how shoul...
Sorry if this is extremely basic, as part of our program we had to install(?) RTOS on our boards to do some of the labs, but we had to reinstall ST-Link after. Now the board refuses to debug. I'm getting these logs:xPack Open On-Chip Debugger 0.12.0+...
Use CY7C1441KV33 to expand memory space on STM32H7A3, with the following connections：：The timing requirements for burst read and write of CY7C1441KV33 are as follows: (1)Read timing: First read the data of CY7C1441KV33, and then add 1 to the intern...
Hello Everybody,I’m developing a Class 0.2 energy metering system for 1-phase, 3-phase (3-wire), and 4-wire configurations. I plan to use the STM32H7 series MCU due to its high performance, Ethernet support, and peripheral flexibility.However, in my ...
Hai.., We are using a custom board with STM32H743IIT6 soldered to it. For our application, we need more Analog Inputs so we have used TLA2528 chip. Below is the code for it.. tx_buf[0] = TLA2528_PIN_CFG; tx_buf[1] = 0x00; HAL_I2C_Master_Transmi...
I need to complete a project to use a microcontroller, STM32 and Keil software to measure barometric pressure, ask for guidance or resources,please...
Hi,I am trying to interface the SparkFun Neo M9N GPS module with an STM32F446 MCU using UART4, but I am unable to receive any GPS data. Interestingly, when I switch to USART1, the module works perfectly.Could you please help me understand why UART4 i...
Dear Support Team,I hope this message finds you well.I am currently working on a project where I am trying to interface your BNO085 IMU module with an STM32L433RC-P Nucleo board. Despite numerous attempts, I have not been able to retrieve any meaning...
Greetings,We've found several STM32 MCUs with what appear to be poorly executed laser engravings. Is there anyone I can contact to get an official opinion on these chips?We are not the firm that designed and built the boards. We are reviewing other f...
