Posted on March 24, 2016 at 15:33I'm trying to set up the RTC on the Disco, have read some documentation, and looked at the many examples that are out there. But I fell at the first hurdle: RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR,ENABLE); ...
Posted on March 24, 2016 at 09:20Hi. We have a variable (one word) which is changing constantly. Up to 200 times per second. We would like to store its value even if power goes down. Do you have any idea how to do that in the most elegant way? We ha...
Posted on March 23, 2016 at 14:26Hi, I am using STM32f405, and CMSIS dsp library, to filter a signal acquired by ADS1278. The filter used is a 12th order bandpass butterworth IIR filter whose coefficients generated by matlab, and my signal is 2430Hz...
Posted on March 24, 2016 at 08:57I am wondering how can I figure out the correct way of defining STM32F334 USART Hardware Flowcontrol pins (CTS/RTS) in StdPeriLib.They should be PullUp/PullDown/NoPushPull or ....Or better to say what should be the m...
Posted on March 24, 2016 at 04:49On the STM32F303 I am attempting to use a timer OC to trigger two DMA requests - one to output a value on GPIO, and the other to update the CCR value on the timer channel to set the next OC trigger point from a list ...
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 ...
