I am looking for an expert to help me with I2C bus on STM32F407IGT. I2C3 is working as expected and I would like to make working also I2C1 and I2C2 which I have problems with.I am using the same initialization regarding registers and I can see the ri...
Hello,i try to implement a 40kHz frequency burst with my NULCEO STM32F411RE. Until now i toggle the GPIO continuously in the HAL_TIM_PWM_PulseFinishedCallback function. But now i have to implement a start Trigger to do a small 40kHz burst. In the att...
It appears that there is some unusual behaviour taking place when I read the time shadow register from the RTC. My application reads the RTC every 1000 systicks and prints the information.When the subsecond component rolls over to greater than the s...
I have the package LQFP100, so the Application Note specifies that there are 3 fast channels, but the Reference Manual says that the first 6 input channels are fast channels. How is this? If I have to configure them as fast how can I do it or where c...
Now in China, all distributors don't have STM32F105RBT6, but if we ask from sub-distributors, most of them have massive in stock, just the price is very very high, about 14usd. So, please tell us when the supply can be normal, because if we switch ch...
I generate the STM32 Project and define each PIN.PIN1:GPIO_OutputPIN4:TIM2_CH1PIN7:SYS_SWDIOPIN8:SYS_SWCLKAnd I let a code below run but it do not reach "while". /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_TIM2_Init(); /* USER COD...
MCU: STM32F769Thank you for helping.I may want to reset the microcontroller while the program is running.What kind of method is there to reliably reset the microcomputer in terms of software?Thank you.
