Greetings everyone,I'm thinking of a setup where a STM32H7 series chip is witha 1.2V regulator powers the core directly bypassing the LDO (REG1)another regulator whose output can be switched between 3.3V or 1.8V (default 3.3V on power up) powering th...
In "prioritized preemptive scheduling", able to send the data to UART from each task.For the round robin, I set the time slice of 200 ms.Have the doubt like how much time taken to change the state of UART handle from "Busy" to "Ready"?.
Im using F030F4P6 controller. Here's TIM16 configuration:Here's clock configuration:main.c: /* USER CODE BEGIN WHILE */ while (1) { toggleAll(); delayUs(1000); /* USER CODE END WHILE */...delayUs function:void delayUs(uint32_t delay) { us...
Hi,I started working on stm32f103cbu6 uC recently. Whenever i try to enable ADC1/ ADC2 , debugging terminates abruptly insideADC_Cmd(ADC1, ENABLE); at ADCx->CR2 |= CR2_ADON_Set;The same code works with stm32f103cbt6. I tried with example code in st ...
External interrupt errata?I have setup EXTI_Line12 and EXTI_Line14 to generate en interrupt.But the EXTI15_10_IRQHandler() fails to execute a second interrupt if it happens too close to the first interrupt.But it seems only happen when I use bit-band...
I'm having trouble getting the ADC on a STM32L476VGT6 discovery board to work. If I run by configuration code then click the ADSTART bit in the debugger, everything works fine. If I set the ADSTART bit in code in real time, the conversion never fin...
So, we are creating firmware for the STM32F7 that takes pictures and stores them to an SDCard. We have implemented kind of a custom database format which stores a kind of file allocation table in RAM, makes the edits as necessary, and then copies the...
Hi.I'm experiencing a very weird problem with a design, a CAN bus keypad with RGB backlit keys, in which the MCU (STM32F072C8T6) would sometimes overheat to over 150ºC and stop working. This happens some times in first power up of a unit, or after a ...
In the STM32F446xC/E datasheet, DocID027107 Rev 6, footnote under Table 11. Alternate function says:1. The DCMI_VSYNC alternate function on PG9 is only available on silicon revision 3.However, neither DBGMCU_IDCODE description in RM0390 Rev 4, nor ST...
When i m using circular ADC1 DMA and writting data on sd-card,mostly data lost, why?
