Posted on August 16, 2013 at 15:59Hello, I understand the STM32f407-VG chip used on the Discovery board has 16 available ADC channels - how many are actually accessible on the board? Some of the ports seem to be assigned to e.g. the MEMS sensor, mic...
Posted on August 16, 2013 at 17:15Hi, Being new to the list, I don't know if this will be of any interest, but i spent some time porting my boot monitor (http://www.umonfw.com) to the STM32F4 Discovery with the STM32F4DIS-BB expansion board. I've b...

Posted on March 05, 2013 at 22:57Hi, I just got a STM3220G-EVAL board. I have to connect an I2C device, but first of all I'm trying to access via I2C the LIS302DL accelerometer on board. Unfortunately, I can't find any example for that embedded devi...
Posted on August 15, 2013 at 16:36Hi, I've a problem with the SP interface. If I reset continously the uC (maybe interrupting the SPI communication would do the same) sometimes the receive buffer gets a 4-bit offset. I do communicate with 8-bit valu...
Posted on August 14, 2013 at 18:34Hi, if anyone is interested, see my problem and thanks in advance. I am using STM32F4discovery, but the problem should be general enough for all STM32 MCUs. I am just curious if it is possible to make : 1. Say, usar...
Posted on August 14, 2013 at 18:35Hello, So I tried every setup I could come up with, and had no luck. Does anyone have an example of using the Vrefint and Temp sensor ADC channels? Thanks #stm32 #internal-temperature-sensor #adc-vrefint #vrefint...
Posted on August 14, 2013 at 14:25Strange problem...Timer 2 works great when debugging. When I turn my supply off and reboot, everything is hunky dory except timer2. Any clues? TIM_DeInit(TIM2); //ENABLE CLOCKS RCC_APB1PeriphClockCmd(RCC_A...
Posted on August 14, 2013 at 18:11Hello, I am attempting to remap pins PD0 and PD1 as GPIO and whenever I try to change the pin state, it stays low. Am I setting something up wrong? Init Code: GPIO_InitTypeDef GPIO_InitStructure; /*GPIOD Ou...
Posted on August 14, 2013 at 20:21Greetings developers and hackers! I have created two spaces over on reddit for people to discuss, share, show-off, ask questions about, etc. their projects which are based on the STM32F4. You can view the posts wit...
