Posted on December 09, 2014 at 20:10 BYPASS_REG = High, VCAP = 1.2V (supplied externally), VCC = 1.8...3VResult: NRST is driven low constantlyby the MCU, nothing works. The same board works OK when BYPASS_REG = Low and the core's external supply dis...
Posted on December 08, 2014 at 16:42Hi everybody,I recently bought a STM32F3Discovery board for a project. I made some experiments and tried to get an idea of how it works, and then I decided to set up a VCM in order to have better feedbacks from th...
Posted on December 09, 2014 at 00:08Hi,when compiling an example in STM32f303_DSP_STD_PERIPH _LIB 1.10 I get lot of errors. then I check the project options (IAR) and the selected controller is arm7tdmi! Changing the controller do not fix the probl...
Posted on December 01, 2014 at 16:34Hi everyone, I'm trying to connect STMl152 at Debug mode (JTAG) but with no success. If i tracing the startup it stuck in SetSysClock (''system_stml1xx.c'') function on : /* Wait till PLL is used as system clock s...
Posted on December 08, 2014 at 18:18Hi I am still (trying to learn) learning how to code STM32F devices using Keil MDK and maybe foolishly, made a pcb with a STM32F383CC6 on it.Firstly how do I use the Keil MDK or CubeMX when it does not appear to r...
Posted on December 08, 2014 at 17:10 Hello, I have a big mystery, based on incremental rotary encoders. I use a PEC11encoder http://www.adafruit.com/datasheets/pecpdfto control my STM32F4. I have no problem with it, it's work...
Posted on December 08, 2014 at 15:39I use 429 UART1 with FreeRTOS. UART1 make an interrupt and 429 enter into ISR. But it hang in the FreeRTOS code line: configASSERT( ucCurrentPriority >= ucMaxSysCallPriority ); which is in function vPortValidateI...
Posted on December 08, 2014 at 23:36I would like if the F7 series will use the same ADC chip and if his maximum clock will still be 36 MHz .If it is the case, the maximum possible ADC clock at 200 MHz will be 25 MHz?Thank you.
Posted on December 05, 2014 at 17:27 Dear all, I need to use the external trigger with ADC1 but I am not able to do it. I have done my code in step. I did make work my ADC1 with TIM2 as internal triggered. That worked well. Then I have I ...
Posted on December 08, 2014 at 19:59TIM5_CH2 will output a 1Hz continuous square wave at 50% duty cycle. The output is to synchronize is phase with a 1Hz externally input square wave also at 50% duty cycle. When the 1Hz input is lost TIM5_CH2 is to ...
