Posted on June 04, 2015 at 22:00I'm trying to get an ADC input to work on the Discovery STM32L053 board. The VREF calibration value is 0x68D, reading channel 17 shows 0x5E9, which by my calculations makes VDD 3.325 volts, which matches what I read o...
Posted on May 29, 2015 at 02:55Hi,I am developing codes on STM32L0 microcontrollerI want to add flash read out protection function in the code.After I enable the PcROP(proprietary Code Read Out Protection), my codes do not work anymore. It does not ...
Posted on June 03, 2015 at 05:14 Must say the CubeMX generation tool is very good, and it really does make everything simpler. However, I run into a situation where I am using the STM32L051 and STM32F051 to test on a project connecting to the bl...
Posted on May 21, 2015 at 01:14It seems power pin on the generated pin assignments (especially pin 19 - 22) needs to be verified. Pin 21 should be VREF+ instead of VDDA?
Posted on June 03, 2015 at 19:20Hi,For a project I need to use internal band gap (V-Ref). so i want to know how to: 1- turn-on internal band-gap voltage reference 2- select internal band-gap voltage as referencetanx all #adc #stm32f103 #v-ref
Posted on June 04, 2015 at 00:35Can somebody explain me how to find cause of hardfault? I try to use solution from http://blog.frankvh.com/2011/12/07/cortex-m3-m4-hard-fault-handler/but buffer is empty.Here are core registers dump (from keil UI):SP ...
Posted on May 14, 2014 at 15:07hi all, i was debugging happily my code on my new discovery F4 board when suddenly got this error please, could someone help me to fix this? may be that something burned inside my board? thank you so much Gio
Posted on December 18, 2014 at 11:43Hullo guys , This is my first time to use STemwin GUI library , everything compiled fine , and the code is simple enough just to test it int main (){ RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_CRC, ENABLE); GUI_Init();...
Posted on June 03, 2015 at 21:02I'm developing a printer controller board (with STM32F070 mcu). Now I need to add USB printer device. I'm using STM32CubeMX with STM32Cube_FW_F0_V1.2.0, but I don't found any examples about. Can anyone help me? Regar...
Posted on June 03, 2015 at 18:12What determines the conversion time of the onboard ADCs?I am having problems when I move from a MCU system clock frequency of 72MHz to 65.536MHz #adc #stm32f303
