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...
Posted on August 13, 2013 at 16:05Hi, Could someone explain me how external clock for timer is done. Specially I don't understand how TI1, TI2 etc., are mapped to the physical pin. Alternate function on GPIO is mapped to different timers but is it ...

Posted on August 14, 2013 at 16:21> In slave mode WS (Frame sync) signal is ignored. It is not ignored. Rather, the I2S state machine does not reset at an edge of WS, as might be expected, but at level. That's why the slave should be started when th...
Posted on August 13, 2013 at 20:25I'm trying to get my STEVAL-IBD001V1 (STM32L-Discovery + STBLC01) board to operate as a BLE master. There's no example code provided in the software package to do this, nor any obvious way to scan for advertisers. I...
