Hi,I'm using STM32F429 to talk to TI BQ40Z50 via I2C, and I ran into an issue I have no clue.First of all, the code simply reads registers, and it works on TI BQ20Z95. The same code doesn't work on BQ40Z50. The HAL library always returns HAL_BUSY, an...
I've read often about strange problems with activated D cache on M7 core and how it can be solved here in forum.But the STM32F7xx family has implemented a fast DTCM RAM that is accessible from CPU core and DMA peripherals.This DTCM memory should have...
I have successfully configured the adc watchdog. But i am a bit dissapointed of the accuracy. I set the bounds to 1000 and 3000, but when i read the values of the adc from the watchdog interrupt, i get also values from within the window (up to 1025/2...
I have Nucleo G0B1RE.I had add 3V battery to VBAT.I had change to use LSE for RTC.I had add RTC_BKP_DR to keep time before reset so RTC time reg was not cleared after reset but It was re-initial while booting.But RTC don't count while power off and R...
Is there a way to generate multiple pulses of different lengths with a timer?This is needed to perform a double pulse test, by controlling the B6-Bridge Driver of a B6-Bridge. The first pulse is longer than the second pulse (e.g 300 us). The second p...
Hi.I'm using PlatformIO with stm32duino with a NUCLEO-L476RG. I finally figured out how to configure the clocks in CubeMX and then copy the "void SystemClock_Config(void)" function into my main.cpp code and it seems to work great.One question I have ...
Hi everyone!I use 8 MHz external oscillator for my MCU. For TIM1 there is no prescaler in CUBE, so I expect this timer to tick with pure 8MHz frequency. And therefore I expect to see 0.125 us * 2 * 2 = 0.5 us period of signal. But actually I have 24 ...
I want to use Telit SL869 GPS card with STM32H753VIT6/STM32F103RB microcontroller. I am planning to communicate with UART. Is there a library I can use? What should I do?
