Posted on February 20, 2013 at 03:50I have made baseboard PCBs for the Discovery-F4, Discovery-F3 and Discovery-VL that break out the signals to separate connectors for various ports and interfaces. I am offering the PCBs for sale if you would find...
Posted on February 17, 2013 at 00:39 Hi all, I am using fatfs as file system and I need to handle the end of file but I didn't file something equivalent to while(! feof (golf)) In an example available on fatfs, the end of fi...
Posted on February 16, 2013 at 18:02 hi everyone, i want to make a simple comunication from usart2 to usart3, i have shorted usart2_tx (PA2) to usart3_rx (PB11). The program send 8bit from usart2 to usart3 and ceck if the transmitted dat...
Posted on February 15, 2013 at 20:48I use my STM32F0 to communicate with an SPI slave device, which is powered by the 3V bus on the STM32F0.My problem is that when I reset the STM32F0, the bus power is not interrupted, which leaves the SPI device in...
Posted on February 15, 2013 at 17:35Hi, I'm using CMSIS to set up an I2C driver. As an example device I have an EEPROM - tried and tested on PIC18s, so I've been through the learning curve for I2C - just getting it going on STM32. Configured CLS an...
Posted on February 15, 2013 at 08:14Hi, I am new to this STM32F30x series microcontrollers. For my application i am using the channels ADC12_IN6 and ADC12_IN7 in Interrupt mode. (Without DMA).These GPIO's are configured as a input pins(PC0 & PC1) a...
Posted on February 11, 2013 at 01:30Hi All, I'm making a PCB that has two STM32F4 DSP chips across an isolation barrier. I need the two chips to communicate as fast as possible, with the one chip (slave) passing new values to the other chip's (maste...
Posted on February 15, 2013 at 16:31I am receiving an unexpected status value from within my I2C ISR. The value is 0x84 (TXE and BTF bits set). For now, I am only doing i2c master transmits, (I have a multimaster config but the other slave is not se...
Posted on February 15, 2013 at 04:56I am currently migrating from F1 to F4. Am getting very frustrated. After many reviews of my presentation on F4, I get feedback that : to a lay person, the current project deliverables does not warrant 12 weeks of...
Posted on February 14, 2013 at 14:54Hello, I need to connect an ENC28j60 module to STM32 Discovery. As there is some peripherals on board uses SPI for communication, i dont know which is the free to use SPI. I hope the SPIs used by peripherals is ...
