Posted on July 21, 2015 at 17:15I design a board based on Stm32f429-discovery and add a 8192 Row x 512column x 16 bit Sdram to Sdram Bank 2. my Sdram is MT48LC16Mhttp://pdf.datasheetarchive.com/datasheetsmain/Datasheets-19/DSA-364195.pdf I study Dat...
Posted on July 20, 2015 at 23:34Hi All,I need to transfer a large amount of binary data to my STM32 and am trying to figure out what the best way to do this would be. The data throughput needs to be roughly 8Mbps. The device has USB so I was thinkin...
Posted on July 21, 2015 at 21:27 Hi All, I'm configuring my DMA to transfer 48 bytes of data, and am triggering the DMA interrupt both on TC and HT events. Currently if I disable the DMA after the first interrupt, so I would expect to see...
Posted on July 21, 2015 at 22:20I am running the stm32f407 at 1.85V and was wondering if it would be possible to get USB working at this operating voltage. I've pulled up the d+ line to Vbus but cannot get proper enumeration. I believe as long as th...
Posted on July 21, 2015 at 20:51Hello folks,I am working with an STM32F7 Discovery board which uses an STM32F746NG microcontroller.I would like to use the I2C peripheral without using the STM32Cube HAL, just by directly accessing the registers.I man...
Posted on July 21, 2015 at 21:24Hi , I'm driving a 1.4'' TFT LCD on STM32F4 Disco , via SPI3 . I wanted to increase the speed of writing to the LCD so I decided to use DMA. The code compiles and work nicely but still too slow and no difference can b...
Posted on January 05, 2015 at 22:48Hi,I have installed STMstudio 3.3 on win7 x64, and I have installed java x86. (http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html).When I want to run, I select ST-Link SWD,but I get...
Posted on July 15, 2015 at 01:11I'm thinking about using a STM32F030 in a slave application where a master may need to reprogram the STM32F030 via the bootloader in the field. I have had good success with this using STM32F100 parts as bootloader sl...
Posted on April 06, 2014 at 06:30Hi all! I want to control 3 phase motor (I get HDD motor from old HDD), and now I can generate 3 PWM signal on 3 channels but they are same, not shift phase 120 degree! Please help me! I use STM32F4 discovery board a...
Posted on July 21, 2015 at 14:07We are using the L152 processor in a new design. This is the first time we've used the STM32 family and it is mostly working wonderfully. However, on the three prototypes we have, only one crystal oscillator works rel...
