Posted on March 23, 2016 at 15:11Hello, I'd like to monitor battery voltage (V~8volts) using comparator and voltage devider with two resistors (1-10M). Coud you please specify analog comparator input impedance, so i can select appropriate resistor v...
Posted on March 24, 2016 at 04:48Hi I had a couple of questions. I'm from the software side of things and hardware is new to me!I am starting a project where I'd like to drive around 5 colour lcd's.It's a bit tricky in that I'd ideally like a mobile...
Posted on March 23, 2016 at 20:34Hi, first of all I'm sorry for the offtopic, but there is no smart meter IC section on the entire forum, which is odd.I've a functional prototype of a Smart Meter running on a STM32-F0/STPM10 platform. Before enterin...
Posted on February 27, 2014 at 21:56Hi, If you set the PLL speed of the micro to 160MHz (PLL_M=25, PLL_N=320, PLL_P=2) then the generated software correctly contains the line in SystemClock_Config(): HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_L...
Posted on March 22, 2016 at 18:41I'm unable to program a STM32 using the STLink2 when the micro has firmware running that puts it into stop mode.I've played with the reset sequence settings in Keil but none of them solve my problem.Does anyone know ...
Posted on March 21, 2016 at 18:02 Hello, I want to read ADC1 CH0 and ADC2 CH1 in dual regular simultaneous mode and buffer it in DMA. I want to send the ADC values via UART to my PC and read them from the COM Port. When I start the program n...

Posted on March 23, 2016 at 08:27Hi ,Can any one tell me,Whether LTDC is DMA or not?LTDC is basically working as blocking or non blocking?By Tamilselvan
Posted on March 22, 2016 at 20:10I'd like to use an STM32L4 in a project where I am interfacing with a 1-MSPS, 16-bit SPI ADC (LTC2378-16). Obviously the SPI clock has to be > 16 MHz to run this at full speed. However, for best performance the clo...
Posted on March 21, 2016 at 10:13Hi i am using f4 and it works with the polling method. But it doesnot work on DMA.. i am getting SDIO_IT_RXOVERR error. Can anyone help me ?
