A customer has a board with STM32F746 and QSPI flash.The board looks as derived from STM32746G-DISCO, though I'm not 100% sure.Their program has data in the QSPI flash, and they flash the app using J-LINK and Segger J-Flash.Now, I cannot figure out ...
Hi,MemManage Fault occured in ITCM when I changed the system clock and DMA channel.Does ITCM cause errors? What are the causes of errors? Any ideas?I changed below:system clock: 480MHz→400MHzDMA: DMA2_Stream1 →BDMA_channel0
I am trying to interface Microchip MCP4261 digital potentiometer with my STM32F401 based Nucleo-64 board.. Can somebody share the libraries for the same? Thanks.
An example is while( (I2Cx->SR1 & I2C_SR1_ADDR) != I2C_SR1_ADDR)breakpoint on this line means I loop indefinately, breakpoint before and after and it reads ok?I'm using EWARM.
I am building a test stand for motor stators. I planned to energize coils and use the demo compass to check coil identity and polarity. Just looking at the indicator would be sufficient but it may be useful to read the magnetometer via USB.I think ...
Hello Everyone,I would like to ask you if you have any more information about an issue I'm incurring in.I am trying to setup a project on a custom board with the forementioned MCU, on which I need to use the first 4 SPI interfaces with DMA for quick ...
Hi All, I'm using STM32H743ZI2 Nucleo board to connect to internet but I have a hard fault error.I'm try enable MMARVAILD bit in SCB->CFSR to hold valid fault address (SCB->CFSR |= (0X1UL<<7);) but it's still 0 after set command.Please help me to che...
