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...
Posted on April 27, 2013 at 08:12I am using stm32f107rc for rs485 communication through usart1 and usart3. i am receving a set data from usart1 to an array and trying to transmit the same set of data from an array through an usart3. it works fine fo...
Posted on April 16, 2013 at 12:40I have an input 8 bits parallel bus, with a CLK signal connected to GPIOs. The frequency is 1MHz. I need to configure an automatic DMA transfert from the 8 bits GPIO to a memory buffer (dual buffer mode would be grea...
