I've taken over this project that is using the STM32h755 CPU. The software is not currently using the Cortex-M4 processor inside the chip. I'm reworking the software so that it will be able to use it sometime in the future. But, until then, I was hop...
I am currently using STM32CubeIDE and want to input an external sine wave. The signal has a voltage of 2.6V and a frequency of 10kHz, and I am using DMA + TIM + ADC. The following is the screenshot of my settings. Currently, I can only capture the pe...
HI, i use CC2 on TIM1 set as input capture measuring pulse period and store in array /* USER CODE BEGIN TIM1_Init 1 */ LL_DMA_SetPeriphAddress(DMA1, LL_DMA_CHANNEL_3, (uint32_t)&TIM1->CCR2); LL_DMA_SetMemoryAddress(DMA1, LL_DMA_CHANNEL_3, (uint...
Hi,We are currently in the process of selecting components for our project, and we have identified the STM32U5A5QJ9 (STM32U5A5QJ), foot-print size UFBGA 132 7x7x0.6 P 0.5 mm) microcontroller as a potential candidate. However, upon reviewing the datas...
im using STM32F103C8T6 , Im using it without any problem but yesterday i upload code , the code is not correct then i make some changes and upload again then it showing this error i use both ST-LINK UTILITY and STM32CubeProgrammer , i follow some s...
Hello,I have a project which demands the device to work in ultra low power mode. I have opted STM32L4R9AI mcu for this project. The problem is i have a spi based lcd display and i need to display the content constantly without flicker even in low pow...
Hi, I have three buttons - START, STOP and CH_SELECT which are serviced using EXTI interrupts. I have also a rotary encoder (A and B pins). Every button line is serviced on a separate IRQ line. Debouncing of the switch and rotary encoder pins is han...
Hello,I am trying to use the quadrature encoder mode of the TIM in the STM32U585VITx, for positioning purposes of a stepper motor movement.According to DS13086, page 79, the general purpose timers (TIM2, TIM3, TIM4, TIM5, TIM15, TIM16, TIM17) support...
HiI want to use a STM32F072 (max. 48MHz) to monitor an external clock.The external clock has a frequency of 38.4MHz.My idea is to use timer TIM3 (32bit) as counter and use the external clock as clock source (external clock mode 1).I read the datashee...
helloI am developping on a STM32G0B0RE, I've learned after finishing my board and everything that boot pin can be used by default.It is not a problem since I have ST-Link for production but I would like to be able to do firmware update through bootlo...
