Posted on July 21, 2015 at 14:44Hello all,I am writing an application on a STM32F4 which reads from two sensors. I do it with two ADC3 channels with DMA. I use HAL_DRIVERSI write on a buffer several readings from three sensors by calling:HAL_ADC_Sta...
Posted on July 22, 2015 at 07:35Hi there, I'm trying to do a blocking I2C read in another interrupt. If I receive a NAK the HAL seems to crash (I'm seeing uwTick stop). Both the I2C interrupt and the interrupt I'm doing the read from have a lower (h...
Posted on June 16, 2015 at 02:56 Greetings. I am trying to use STM32F3Discovery(STM32F303VCT6)I2C interface to communicate with24C04 EEPROM device. And as for now all my attempts failed I've decided to ask for help. I initialize I2C1, then ...
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...
