RTC: Tamper sampling frequency
Posted on February 13, 2015 at 13:19HiIt was not clear from the datasheet, but is the TAMPFREQ register only applicable when using level detection and not edge detection?I am asking as PC13 (RTC_TS) is not available on some low pin count packages an...
How to generate dutycycle for ESC controler using STM32F4
Posted on February 12, 2015 at 18:49 I have some brushless simonk ESC`s driving my brushless motors. I noticed that these esc`s are woring on a 1 to 2 ms pulse from a 50hz signal. Wich in duty cycle terms means that i must work with duty...

Flash Memory check in STM32L0
Posted on February 18, 2015 at 10:34Hi all,I would like to check my whole flash memory integrity. I´ve the posibility of read the whole sectors and calculate a CRC and check if it is correct by firmware. My question is the following one. Is there an...
3-way Simultaneous ADC-DMA Sampling inversion glitches
Posted on February 18, 2015 at 16:49 We are currently working on using the three ADCs on the STM32F407 to simultaneously sample three analog waveforms. Our target waveform is at about ~30Khz, but to illustrate our problem I have slowed the input...
GPIO_WriteBit() in HAL ??? (32f407)
Posted on February 14, 2015 at 21:31Hi there! Who knows how to implement the function of GPIO SPL - GPIO_WriteBit (GPIO_TypeDef * GPIOx, uint16_t GPIO_Pin, BitAction BitVal) on the library HAL? In the HAL library I can see only HAL_GPIO_WritePin(GPI...
