Hi ! Im generating pwm at 200khz with no problems. But when I use timer to generate interrupt I get max 100khz of pulse on pin. No matter if I use HAL_GPIO_Toggle/WritePin or just GPIOx->BSRR. No matter how low value of timer prescaller I use.Outpu...
Hi!I am confused, i wanted to use STM32F042F6P6 MCU for can interface but, ther is no TX pin for can interface (PB9 on datasheet). So, how i can configure CAN TX?There is no CAN mode option for this MCU inside of CUBEMX because there is no TX pin for...
Hi team,I am using STM32F103RDT6 for my project. I would like to know the details of UART in the MCU. in the datasheet it shows 5 USART interface is possible. At the same time 2 UART is also mention in the datasheet.So my doubt is that can I use the ...
Are there control signals available that would allow me to "unmux" the address/data lines using external latch? I need to use the LQPF144 package that doesn't provide the separate Address and Data pins - they are muxed.
Using HAL. How to read unique ID and use it to identify specyfic chip?Do simple:uint32_t HAL_GetREVID (void ) uint32_t HAL_GetDEVID (void )Do the job? Are they really unique, or can these values repeat in same chips?
Hi,i want to put my device STM32L010 for 5 minutes in stop mode. Then wake up to measure something with ADC and go in stop mode again.How can i handle the IWDG in stop mode? According to the reference manual, the timer cannot be stopped. ???17.3.4 Be...
No1 is TIM1,No2 is TIM2,No3 is TIM 3, No4 is TIM 8,the master TIM is TIM1, TIM2/TIM3/TIM8 are slaves; but in the begging of TIM2，have a long time High level。The MCU is stm32f207vct6. My Emaill is 595779344@qq.com; I need help, I need Technical sup...
Hi,I bought the stm32f401 board from aliexpress."WeAct" print is on the back.Seller's site do recommend the DFU method to program the board.But, I want to use ST-Link, so I made a simple program to control gpio port. Fusing by ST-Link seems to be goo...
I am trying to do serial port communication using the standard Peripharel Lib. But Std has changed a lot compared to other versions. In the older version, the following code block worked fine.Old version of code block written with peripharel lib. /...
Reading this cell: 0xe0040000 will hard crash the CPU. You can do it from non secure code also, which opens the way for a possible denial of service attack.In gdb:x/x 0xe0040000I realize parallel trace (the tpiu reg in Q) is not implemented but...
