Posted on April 24, 2012 at 09:13Hello everybody, I have some troubel to communicate with m24LR64. I use a STM32L- Discovery. I try to see something in the oscilloscope but nothing, could you help me to see what is wrong in my code: #define I2C2_SLA...
Posted on January 02, 2015 at 06:46Hi, just soldered my STM32L151CB 48Pins with below configuration :1. SWD, both SWDIO, SWCLK (no pull up or down), VDD, GND connected to STLINKV22. Boot 0 (NC) 3. OSC32 I O, OSC I O (NC), i used to use internal osci...
Posted on August 08, 2013 at 21:17I faced a critical problem of i2s of STM32.I'm developing a simple system for i2s level meter.MCU - STM32F103RCT6 with external X-tal(12MHz), 72MHz of running clock Inpit Audio - 48KHz, 16bits, stereo i2s digital au...
Posted on January 05, 2015 at 17:44I have relocated the Vector Interrupt Table as follows *((volatile uint32_t *)0xE000ED08) = 0xFFFFFF00 & 0x08004400; // jump to bootloader pVector = GetBootStartEntry(); asm ...
Posted on December 20, 2014 at 16:41Hi everyone,I was wondering if there is a tool like STM32CubeMX to generate initialization code with the standard peripheral library.The Cube is too new and still needs to mature but i do like the STM32CubeMX tool...
Posted on December 19, 2014 at 08:06I've Keil project with three targets, when re-generating project in CubeMX and launching the project i get error ''Target '' already exists''. Need to modify .uvproj file by hand to define targets. Anyone else, is...
Posted on January 06, 2015 at 11:01I am a newbie to STM32. I would like to migrate existing solution to STM32 which uses a button library that can detect double-press, triple-press, long-press, very-long-press etc.Is there a button library available...
Posted on January 06, 2015 at 11:20Hello, the STM32L0 series sets nearly all GPIO to analog mode as default. This does make sense opposed to the ''default to input'' on other family that may result in high current draw with floating inputs. Only Por...
Posted on January 04, 2015 at 04:11My project involves using a STM32L152 part as a SPI master that receives data from a slave (digital accelerometer). When I look at the SPI signals through a scope, I notice that the incoming SPI data is being inter...
Posted on January 05, 2015 at 14:21I have a new STM32f4 Discovery board and would like to be able to build, burn, debug programs in Ubuntu linux version 14.04. I basically followed these directions: http://www.wolinlabs.com/blog/linux.stm32.discover...
