Posted on April 24, 2013 at 16:49I am working with stm32F0 ADC & DMA peripherals and i have to convert 4 channels.The ADC is triggered by the Timer1.My problem is that i obtain the result correct but there is a permutation between 2 channels(the ...
Posted on January 03, 2012 at 09:36ADC Tests with stm32value eval board. PC4 as AD Input, conversion all 20msec, 20turn Pot with 22k u1 RC Filter to PC4. Software looks for max and min adc values. I let it run for 30000 conversions: I get errors up ...
Posted on April 19, 2013 at 16:49VDDC should be 5uA, AVDD should be 2uA. But I have 500uA. I tried to enter in the stop mode before and immediately after the system_init, without any initialization settings. Tried also to do pins IN, FLOAT, AF. Sto...
Posted on April 30, 2013 at 11:02Hi.I have a problem with FMSC. I want to use FSMC single synchronous burst transfer with PSRAM. The memory has a 16bit data width and i read into ref. manual that ''When the selected bank is configured in synchronous...
Posted on April 28, 2013 at 23:08 Hello I am trying to setup he alarim to wakeup my MCU from standby everyday at 12:00 but it seems that some times the alarm nor occurs and some it occurs .. what i miss in my code? RTC_AlarmCmd(RTC_Al...
Posted on April 28, 2013 at 09:27I configured ADC1 and ADC2 on fast interleaved mode and use DMA for ADC data transfer. I expect that when I call the StartConversion function of ADC1, the ADC2 should be started automatically by ADC1 after 7 ADC cloc...
Posted on April 27, 2013 at 00:26HiI find problems with capateur internal temperature sensor STM32F4 Discovery, I have measured as false (-80.50...-45.00...-60.50 ).I know if my code is wrong or the formula that calculates the temperature.I hope the...
Posted on April 26, 2013 at 18:25HI, I want to know how to convert the values ​​that provides MEMS accelerometer on g because I need to set the threshold for single /double click detect.For example in the program MEMS in STM32F4-Discovery_FW_V...
Posted on April 27, 2013 at 13:07Hi all, I've the following problem. I need to measure signal on the PC.00 pin and with the code bellow it doesn't work. :( However, if I change the pin to PC.02 and Channel 12 , everything works fine and I get the pr...
