Posted on February 21, 2014 at 23:16 Hello, I am trying to use a STM32F103 (8Mhz external clock) to get the duty cycle of a 20 Khz PWM signal. I am using Timer2 and trying to look at the rising edge using channel 1 and pointing channel 2 at ...
Posted on February 26, 2014 at 11:17Hello,I have a STM32F4 Discovery. It has an on-board STLink V2 debugger that programs/debug the STM32F407 micro. I'm develloping a circuit that has also a STM32 micro and I would like to know if I can use the STL...
Posted on February 26, 2014 at 11:08When i use the flash demo to erase my mcu, i selected erase all and click Next, flash demo tell me ''FAIL: Unable to erase flash''.What's wrong? Where can I get more information about it?thanks.
Posted on February 26, 2014 at 15:39Hi, Which are the differences between ''ST-LINK/V2'' and ''iar I-jet'' over that ''iar I-jet'' power consumption can be measured. (this is the only difference?)
Posted on February 25, 2014 at 11:44 Hi, I think I'm missing out something simple or doing something stupid. I'm trying to do adc conversion on 3 channels on ADC1 continuously (loop). I use EOC interrupt and store the adc value in buffer. ...
Posted on February 23, 2014 at 19:14Hello,I use TIM1 to generate a clock-signal at the gpio-output-pin TIM1_CH1. This signal will be generated until a rising edge is detected at TIM_ETR (gpio-input). So the output-signal will be immediately pulled d...
Posted on February 26, 2014 at 07:03 Hi i am referring to an example from the stm32f4 library. In the comment section : TIM3 Configuration: Output Compare Toggle Mode: In this example TIM3 input clock (TIM3CLK) is set to 2 * APB1 c...
Posted on February 25, 2014 at 16:45I found this problem when debug the CAN bus. The received data can not be showned in the printf via SWO. At first I thought there were something wrong in configuraion. But at last I found that the data can be show...
Posted on February 25, 2014 at 18:16Hi, I am trying to modify function static uint8_t Explore_Disk (char* path , uint8_t recu_level); from USB host example for writing our more than 1 subdirectory and for SD card. I added : else if(recu...
Posted on February 25, 2014 at 04:02 I use the dma to TX only, the rx is handled in a interrupt with no dma. I've been working on this for quite some time now and I Always get a FEIF6 interrupt. Specifically I get TC, HT and FE. I dont h...
