STM32L432KC internal reference
I am working with STM32L432KC in range VDD and VDDA 1.8-3.6V.I have read the reference manual. It doesn't say anything about how to apply the internal reference 1.2V. as a reference of ADC and DAC?

STM322F0- Can timers be used to get precise timeout functionality?
In my project, I want to implement a timeout feature. That is, the user sets the required time and then starts a process. The process then has to end after the set timeout value. Now, the problem is I am able to turn off the process after the set tim...
How to change the clock source using the register?
So, There are two sourse of clocks in STM32.1) Inner RC generator2) External crystal.I need to use second variant. I use asm.I determined the address responsible for choosing the source of clocking. The address is 0x40023800. I wrote down the value ...
SPI Slave Problem: For STM32L151, If SPI2 is configured as SPI Slave, what is the expected frequency from SPI Master for which STM32L151 can transmit data without any issues?
STM32L151's AHB is at 32Mhz and APB runs at 16MHz.Given in the datasheet that SPI Slave clock can be APB clock/2 max.I have tried to transmit 7 bytes of data from STM32L151. I am able to receive data properly if my SPI master clock is configured to 2...
Behaviour of PC13 not as expected.
Posted on March 17, 2018 at 16:25I am setting up a board that uses an STM32F103C8. It has an LED on PC13. I am running FreeRTOS and configuring with STMCubeMX. I am also enabling the LSE clock and RTC.Using Cube MX I configure this and ensure that T...
STLink and target Supply Power
I am working with a STM32L0538 discovery board and am ready to move to my own target board. According to the documentation I can use the STLink/V2-1 portion of the discovery board as the debugging interface for my target board using the CN5 connector...
JTAG to SWD problem with STlink
Hi,I use ST-Link/V2 programmer. I connect my stm32f407 with this circuit to my programmer.Everything works OK.I tend to connect my JTAG connector to SWD pins in my board But when I disconnect Reset or VCC pins from my programmer ( while my board is p...
Resolved! SPI communication between two STM32 gives different values after reset button pressed
Hi, i'm using SPI to communicate two STM32F446REUnfortunately, I get different value after the reset button pressed. Due to some other reasons, these two 446RE use LL and opencm3, but I don't think it is an issue. The code for master in one of the ...
Speed limit in the DCMI and the FMC in STM32H7
The DCMI controller in STM32H7 is faster than F4 and F7. It supports a pixel clock up to 80Mhz. However, is the FMC controller fast enough to acquire such fast data? Let's say, one has an image sensor that generates 10-bits or 12-bits data with 74.25...
Problem: Not generating files
Posted on January 28, 2016 at 20:57The STM32Cube does not generate some .c and .h files for my code.I'm using MDK-ARM V5 toolchain for my project.Whenever I try to create another project the missing files change in random fashion, sometimes its mxco...
