Posted on May 26, 2015 at 07:11I would like to use the PWM as clock source for other device. so I want to know the maximum frequency of PWM. As faster the frequency of PWM signal increase, the more the shape of PWM signal become to triangle signal. ...
Posted on May 26, 2015 at 09:49Hello,I am debugging step-by-step my project on stm32f103vd, using CooCox CoIDE, and ST-LinkV2.when I enable whatchdog, the system go then to Reset_DefaultHandler(). I think that's normal no ?and how I can debug step-b...
Posted on April 27, 2015 at 14:42The user manual for the STM32F051 discovery (named UM1525) seems to be gone from the respective http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/LN1848/PF253215. Some kind of meltdown ? #um1525
Posted on May 18, 2015 at 10:19 I'am using three MAX11210 with a STM32L151VDT6 controller via SPI. I only want to read out the CTRL3 register which is by default 0x1E. If i read out the ADCs behind one another i read 0x1E, 0x1E and 0x1F... but n...
Posted on October 29, 2014 at 14:09I have previously used a timer for triggering ADC for sampling using the standard peripheral library. I am now trying out the STM32CubeMX GUI and generating code from it to be used with Keil. I am working on the ST...
Posted on May 25, 2015 at 16:45 Hi there, I try to send data from PC to my stm32 board using RS232 but each time I send data to stm I get exactly same strange other data for sample: if i send 0x12 i receive 0xc4 always and if i s...
Posted on May 24, 2015 at 16:52Hello, i have a question, since i dont have much experience working with flash... The 32F407VE is 512kbytes flash size, but when trying to read the content of the flash with ST LINK application, the flash range is on...
Posted on May 24, 2015 at 20:48I've startup a board using STM32F072 ( new with ST :) ) ,but cannot get the RTC wake up timer to work, i can see the RTC Registers are moving using LSE 32K crystal in debug mode, thus RTC->DR increase every second.i w...
Posted on May 22, 2015 at 15:33 Hello, Can anyone help in pinpointing where and what I'm doing wrong when seting up USART DMA TX transmission. Working with STM32L152RB (STM32L discovery) and trying to setup USART1_TX overDMA1_Channel4,USA...
Posted on May 25, 2015 at 20:52hello i am using an IAP program to load another program on stm32f4 device. the main program is an uCOS-II RTOS. I have one problem: at first there is no problem to go in to IAP program and then jump to main program. bu...
