I tried to sort through the manual. When I choose external clock do i actually connect anything to the PH0 and PH1 pins and what kind of oscillator.I see that there is already what looks like 8 MHz crystal is this one I am connecting when using exter...
Hello everybody,I wanted to measure the duty cycle (tone) of a PWM signal with input capture mode. Unfortunately, it works only almost up to 65% of the duty cycle(Ton). otherwise will the T_off measured instead of Ton. does anyone have an idea what c...
Hello all,In my Project i m using stm32l031k6t6 microcontroller interfaced with GSM and GPS module and external FLASH memory.For that , first controller read coordinates information from GSM and GPS module and store it into flash memory for record. a...
I will need to handle dynamic memory using malloc and free. Looking on FreeRTOS documentation, I found pvPortMalloc(size) and vPortFree(ptr) , pvPortMalloc(size) works fine. When try to release memory using vPortFree(ptr) inside a Thread, the code ...
Is there a way to have spi just send an abnormal number of clock cycles as opposed to just 8 cycles at a time? Is bit banging the only way? Can the LL library be configured or coded to do such a thing?
Hi I'm using STM32F7 series microcontroller. Is it possible to send 9 bit data using SPI? the reason is i have to send 8 bit data along with command bit (ie 9th bit). I have seen some option in datasheet like we can chose the data length between 4...
Hello,I want to realize a startup-counter in a STM32L0xxx MCU.This means a counter which counts how often the MCU is doing a power fail and restart for the whole life.I want to save the actual counter-value in the flash memory.But I don't want to kil...
If switching GPIOA mode from 'General purpose output' (set to 1) to Alternate function USART Tx:Will level of pin break down for a short time or will it stay rock solid at "1" ?Rem. One has to change MODERy from 01 to 10. One may go via 01 -> 00 -> 1...
Posted on March 04, 2015 at 11:20Hi The latest version of CubeMx in Ubuntu generates (export TrueSTUDIO) file Linker (xxxx_FLASH.ld) empty. I have tested this on STM32L0 and STM32F4. In Windows it all works. Has anyone encountered this problem? B...
Hello, all!I need to explore an option to connect a DRAM to an MCU, and still ahve at least 40 PIOs and 16 AIOs left. and would like your input:Is there a comprehensive tutorial on how to connect and use a DRAM with an STM32?Any specific keywords I s...
