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...
Hi All,I am currently working on the CAN normal mode in a custom board with MCU STM32F098RCT6 and CAN transceiver TJA1042. Very first I tried the loopback mode and it was successful. Then I am now trying to interface two custom boards using the norma...
Hello @Tilen MAJERLE and everyone else,So, I have written firmware to work on the STM32L476RG microcontroller. A part of it is not working properly.I activated DMA on the SPI(SPI1) and UART(UART5) communication channels. I use the SPI to communicate...
Posted on February 16, 2017 at 07:28 1>> We understand thatSTM32F769 DCMI(Digital Camera interface) is able to process YCbCr 4:2:2 and RGB 565. We could see sample camera program in STM32Cube with video input as RGB 565 format to DCMI module and...
Hello, I have created one function to calculate mean of 20 samples of float and run it using math.h and another function using arm_math mean function and check the execution time by making GPIO on and off. I am getting more exeution time for arm mat...
I have the NUCLEO-G432RB, which has the STM32G431RB MCU. The datasheet states that the MCU could operate in different ranges to reduce power consumption. For my application, I need to know how much power the MCU consumes, so connecting a multimeter t...
