Hi, we see STM32H7 has Qspi errata as below: But we are not sure where to apply the patch exactly. It says "upon reset and upon switching from memory-mapped", mean in reset function, right after or before "HAL_QSPI_Init"?
Hello , I want to make 4 channel PWM signal using TIM1 (with complimentory also) .While the TIM1 is used to triger the ADC to get sample .I am getting the pwm wave , But ADC is not triggering or not working . What configuration i require Please s...
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...
