Hello, I'm developing a custom board based on STM32F072B-DISCOVERY board.I have an external PWM source with variable frequency (from 200Hz to 10Khz), i need to count how many pulses it generates. How can it be done? PS. I've tried with Imput Compare ...
The CR1 register stays 0 (as well as CR2, it looks like all UART2 registers are 0). My first thought was that the Bus is not enabled - as UART1 is on APB2 and UART 2 and 3 are on APB1 , but I enable UART2 bus - this is the enable code : /* Enable G...
I have a new product using the stm32l486, and the GPIOG pins mentioned in the title do not appear to work as outputs, even though they are configured identically to the GPIO pins I am using for ports A-F. I cannot find anything in either the datashe...
Hi, I have STM32F407VE and this display which require 5V power:Is it ok, to connect it to 5V and to FSMC pins? I wont demage FSMC pins?
I'm using the STM32F765VIT in a custom board and Trying to test CAN1 CAN2 and CAN3. Is it possible for me to send CAN data from CAN1 to CAN2/CAN3 and vice versa? I have CAN transceivers in them if you had that doubt. I'm trying to send data from CAN1...
I fixed my mistakes from my last iteration of code (reduced 6MHz interrupt rate (which is impossible) to around 35KHz,) and reduced the amount of code in the interrupt. PWM on any timer still refuses to work even though I've enabled them. Is it possi...
My application requires to be started without watchdog enabled (don't ask why). But it seems that once enabled, after a software reset the IWDG continues to run, and if not treated in time causes to another reset. Note that the "Hardware watchdog�? ...
Customer asks me to use STM32 powered from 3.3V with ADC reference 3.3V too (different source). So there is two possibel topologies:Connect VDD and VDDA, use precision source for VREFConnect VDDA and VREF to precision source, VDD connect to standard ...
Hello, I'm using STM32F103 on CUBE MX, when I used an encoder which has only 1 channel, nothing was added to encoder register. I get data from this function: __HAL_TIM_GET_COUNTER(&htim3). So does it has any different when we config encoder mode with...
I ordered a bunch of STM32L443CCU6 chips from element14. I got an email from them saying that there are export restrictions on the chips. I’m based in India. How do I get these chips now?
