Hello, I'm currently controlling a motor with the nucleo-h743zi2 board. I'm sending commands to the motor driver via PWM and reading the encoder's values. I can currently send commands from a PC and receive encoder values through UART communicati...
Hi there ! I start a project with STM32G031k8. This board i'm gonna make is a RS485 slave on the pin 4-5-6-7 of GPIOA i put a dipswitch with pullup resistor , and i read in this way: uint16_t Add = ( 0x00F0 & GPIOA->IDR)>> 4 ; right now my add is 5...
Hii, I was trying to connect microsd card module with stm32, i was unable to connect with it because the SDIO interface was not available at stm32f407 discovery board. also it support spi communication but not getting how to get with it. can some one...
Hello,I'm facing a strange issue with the quadspi peripheral.I'm using it to interface with a W25q256jveiq, a quad spi enabled flash chip from Winbond.As long as I use one line SPI or dual I/O mode all works fine.I can access the flash chip with no i...
Hello,I have an STM32F373 and have successfully enabled a USB virtual com port.I currently send data packets from a PC host to the slave device and include a 'deviceId' in the packet data header.I would like to support the single PC host communicati...
早上好！ 在装机生产中STM32F103RCT6芯片能正常工作，成品机器交付客户使用后出现STM32F103RCT6芯片烧毁损坏的情况。成品机器与客户端通讯接口内信号线是直接连接芯片I/O口，客户端与成品机器联合使用，当成品机器出线异常（后排查为STM32F103RCT6芯片烧毁），客户端未出现芯片烧毁的情况。相关直连引脚为【PB3】&【PB4】，PB3做输出I/O量，PB4做输入I/O量。 请问该芯片烧毁的原因可能是哪些？
I am currently ramping up a new project which has a HyperRAM installed (S70KL1282 - like in the example project of STM32H735G). With the help of this sample project code I can successfully write and read with memory mapped mode from the 16 MB RAM - b...
HI STM Team,I am new to STM32 Board. I am using NUCLEO-F439ZI Board. When I was connecting my USB-OTG side to my PC, I will suffer from the "Unknow USB Device" Error, The error screenshot was attached below for your reference . Please Guide me to rec...
Hi, I am trying to do an application where I am using 2 PDM output digital MEMS microphones to get a stereo sound from them and then play it. My question is when I select I2S as Full-Duplex Master for STM32F407VG it only has 1 SD pin. Should connect ...
Dear all,I've been wrestling with a communication glitch that's been causing me some serious headaches. Here's the lowdown: I've got this control board hooked up to a pump, and I've been trying to send commands to it via USART1 on my own STM32H735G-D...
