Hi, I have an application on STM32F4 MCU which is based on Smartcard T =1 protocol according to ISO 7816. The app works very well. Then I choose other STM32F7 board to test this application, i faced with problems, i can read ATR from SmartCard but i ...
Some sources state that some CAN transceivers disable the entire bus if their node is powered-down (due to low-impedance while unpowered).Some manufacturers (e.g. Texas Instruments, Microchip) explicitly state in some datasheets that their transceive...

I understand the TIMER event can automatically trigger an ADC conversion that gets saved to memory (via DMA)..But if the ADC is configured to SCAN more than 1 channel, does that mean that sample rate per channel must be the TIMER rate divided by the ...
Hi , My USART1 works fine when i send a character and i recieve a character in comport , but i need to also configure USART2 ,i have configured the apb1 register and also apb2enr for the GPIOA clock enable ,i know for the fact that the clock on apb1 ...
# I am willing to pay for a couple of hours help. I have some experience with micro controller but not enough to understand from the reference manual.
I have successfully set up this timer to output one high pulse with following low state.However after finishing the period the output toggles to high until next activation.I need it to be low inbetween activations. How can this be achieved?I tried al...
HiI am trying to get my ADC measurements of the interal chip temperature and data transfer to a global variable via DMA working properly. The ADC1 is triggered every second via timer 4. Configuration is stream0, channel channel 0. I do get several er...
