Posted on September 03, 2014 at 00:58I'm trying to run SPI on DMA Mode for STM32F407 (Discovery). I'm stuck with the below code, with the oscilloscope showing SPI CLK but no data. I'm wondering:1. How do you do slave select in DMA Mode?2. Is the DMA...
Posted on September 03, 2014 at 23:30The STM32F4-Discovery_FW_V1.1.0 library has USB code that I'm using in an STM32F4 project for USB HID support. usb_bsp.h has the board support package function definitions. I'm implementing these for my own cus...
Posted on August 30, 2014 at 23:22Hi Forum, Is there any way to avoid returning from an USART1 interrupt? The booting process of our unit takes some time so we want to jump to the main menu quickly by pressing a key on the keyboard. This works and t...
Posted on September 03, 2014 at 19:53Greetings all -- I have a custom board built around the STM32F303VC, which has separate pins for VDDA and VREF+. In the interests of keeping the voltage reference quiet, a 3.0V regulator is attached to VREF+, an...
Posted on September 02, 2014 at 21:53Hi, I'm working with the STM32F40G EVAL board, and used the STCube to generate USB CDC middleware and it works fine. I am interested in modifying the STCube generated firmware, and having the device enumerate as ...
Posted on September 02, 2014 at 19:14 Hi guys , i am trying to figure out how to get stm32f4 discovery board accelerometer work. After checking the lisd302dl datasheet and reference manual (that wasn't too much helpful) ,i went to forum wh...
