Posted on April 29, 2013 at 09:24Hello, I need circuit, which will be protect ADC input against overvoltage. Also, it should amplification low-level voltage (from sensor for example). Do you have something like this?Thank you.
Posted on April 30, 2013 at 11:37Hello, after reading and reviewing 1 dozen times the RM and app notes, i could not come to a clear conclusion on what type of RAM i can use in STM32F4 100-pin packages. The more clear and detailed info was for NOR fl...
Posted on April 27, 2013 at 21:49Hi All, I've rummaged through the archives but didn't really see what I'm looking for here. We have a few PWM power control designs based on the Atmel ATTINY861A which provides fairly complete support for this a...
Posted on April 29, 2013 at 11:38Hi All, the reference manual is quite confusing regarding this question. Within most it is stated that the medium range devices have a flash range from 64 to 128KByte, while in one chapter this range is given from 32...
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...
