Posted on March 31, 2016 at 21:57Hi,We're trying to reduce power consumption when not suspended and using USB. During the time when we are not handing USB interrupts, we would like to run at a slower core clock speed. I'm wondering if this is poss...
Posted on March 21, 2016 at 19:59I've created nearly identical projects using CubeMX.First one is using STM32F107, 2 ADCs, ETH. When I compile it and run on my target (EasyMX Pro v7 for STM32 ARM), it gets to main loop without problems.The only diff...
Posted on March 24, 2016 at 13:11Having problems getting this to work. I discovered that optimisation may have been the cause of a couple of errors. So, if I turn off all optimisation in SW4STM32 (eclipse IDE + gcc toolchain), I can get the F7 disco...
Posted on March 29, 2016 at 21:14How to use HAL_I2C_Master_Transmit() from outside main.c This HAL_I2C works when I call it from within main.c. I created some external i2c_routines.c, but have a hard time defining how/where to get and use HAL_I2C_Ma...
Posted on March 19, 2016 at 20:50Hello, I am newbie in STM microcotrollers family. Other HelloWorld project work's fine. Now I have new project, I would like show data from memory on microcontroller on my PC. I created project in STMCubeMX then buil...
Posted on March 24, 2016 at 11:17I have a stm32f439 board with a 128MB SPI flash in hand, this board also has a 32MB external RAM. My target is to copy the large scale data from flash to RAM. So far I can read the data to RAM from flash by polling,...
Posted on March 19, 2016 at 22:19Hi: On an STM32F405, I am using ports PA9 through PA12 connected through to a USB Mini B connector. The intention is to use the port so I can plug in a USB stick and transfer data to it. To drive USB power, I have a...
Posted on March 25, 2016 at 20:14 Hi all ! I try to configure my software using STM32CubeMx for a Nucleo-F411RE board. For my own (very lightweight OS) I need a cyclic interrupt of 10ms. But currently I'm not able to find...
Posted on March 24, 2016 at 11:35Hi allI'm using the USB microphone example on STM32L4 nucleo board ad I've modified the source code to adapt the buffer dimention according to the synchronization of the PC request and data coming from the SAI connec...
Posted on March 23, 2016 at 15:03in the stm32F4xx_hal_pcdm.c source file, in HAL_PCD_IRQHandler the interrupt identified by USB_OTG_DIEPIN_XFRC is treated 2 times with the same code. Is it necessary? #hal-pcd-interrupt
