Hello, I am working with the discovery board STM32L100RC. I am trying to have three different timers (TIM2, TIM3, TIM4) as PWM. I'd like to do it's to have each timer ouput at '1' (3.3v) when a boolean variable is equal to '1' and at '0' (0V) when th...
Hello,We are using an USART connection in DMA mode and get the same symptoms as in https://community.st.com/s/question/0D50X00009XkfArSAJ/dmausart-on-stm32f407vg-tc-interrupt-sometimes-not-triggered but the FIFO is disabled.After a while and in condi...

Hi, I just get my STM32L496 board, I'm trying to activate the board at stm32-c2c.com but this website isn't working. There is one video on Youtube about this board, and they use this website. Could you help me pls?
Hello everyone,I think that I am missing some parameter in my calculation. I want to feed the clock to a microphone and I want the output clock to have a frequency of 48kHz x 64 = 3.072MHz. The 48kHz is the audio sampling freq and 64 is the decimatio...
Hi I'm trying use In App programming for the STM32L432KC board. Unfortunately there is no working example provided (app note AN4657 has STM3210C_EVAL and STM32L476G_EVAL which is dual bank). I have managed to modify the example and written correctly ...
For example, What does 'Z' and 'I' mean in Nucleo-F767ZI and what does 'Z' and 'G' mean in Nucleo-F767ZG?In this way, please tell me the meaning of the things that are divided into R, E, B, K, C, etc.
I am building an CAN system which includes sensor modules and actuator modules. There is 1 center MCU which control/communicate with all modules via can bus. I also want to update firmware for each module from that center MCU through CAN bus. Which h...
I used related functions of HAL in Keil to program option bytes. I cannot connect to MCU again after I write option bytes. I think MCU is locked , and I've tried two MCUs , both is locked, How can I unlock this MCU? It's external boot pin seems usele...
Hello, I would like to ask you, if there is any way to calculate the value of sense capacity? I am using TSC peripheral on STM32L083 and I am trying to interpret the output value from TSC. I've read every application note for TSC, and I didn't find ...
