I have the same code that I want to run in several different configurations. I have banked memory. The code will be run from both banks. In order to run the code from bank 2, the VTOR register needs to be set to the IVT address in the second bank. Si...
I'm using Atollic 9.1 with a Cube-generated project on F413 Nucleus board. When I debug (clicking on green bug icon), I get a message that debug failed, with debug context stopped wherever it stopped in the previous debug session. If I click on the g...
I have STM32F446RE which is 180 Mhz, APB1 is running at 90 Mhz which is the timer clockfor prescaler 7 it is 1.04 Mhz6 is 1.19 Mhz8 is 922 KhzI would assume that I could divide 90 Mhz by 90 to get nice 1 Mhz but it does not seem to be the case. I won...
Hi,How to calibrate the adc... I am using Nucleo H743 and my H753 boards. Vref is 3.32V in nucleo, and 3.31V in my board.. when i convert the adc value by simply multiplying with Vre/65536, the result is almost greater than 11.mV (for Vin> 1.0000V) ...
While stm32l4r and stm32h7 have DMA1MUXEN and DMAMUX1RST in the RCC register space, I see no such definitions in STM32G0. Are these definitions missing in the headers or is there really no such functionality in STM32G0
In Single SPI mode, the unused qspi pins are held as follows: IO2 is in output mode and forced to ‘0’ (to deactivate the “write protect�? function) IO3 is in output mode and forced to ‘1’ (to deactivate the “hold�? function)Problem is, all the flash ...
Hi all,I do have a problem with I2C slave transmit mode. Everytime the master (in my case an FTDI FT4222) starts a read access I get the error ACKNOLEDGE FAILURE.If I just transmit from a PC to the STM32 everything works fine and I receive the correc...
Hi,I want to configure the DMA so that it transfers data from the GPIO lines (8 bit data lines) to the RAM buffer upon receiving a trigger signal on the timer capture input channel TIM1_CHI (PE9) . I am using stm32f446ze.We nees to acquire data regi...
Dear,I use SM32L152, I go to STOP mode regularly and as the possible source of waking up is either RTC or External interrupt. It works Fine until I change the System clocks from MSI 4 MHz to for example HSI on 16 MHz. If I change it, then MY MCU is w...
Posted on August 28, 2014 at 12:45I am using timer1 channel 1 as output compare, to generate a pulse of variable period.Desire output � In the beginning the output remain low for 4 ms(delay period) and then pulses of variable periods as 5.8, 3.6, ...
