I'm in search for a library of routines that allow for scanning keyboard matrices with or without diodes in various configurations. I've heard it exists for Arduiono but I'm pretty sure there is such for the STM32 series too (my target is an STM32F10...
When MCU（stm32f105） communicates with flash（W25Q64JVSSIQ）, it is found that the waveform of MISO pin is incorrect. Please tell me why this problem occurs。
I am starting a DSP class project that will be auto-adjusting blinds using the Nucleo-L476RG board. To start off, I am wondering how it is possible to control the Nucleo board wirelessly with an android phone. I am aiming to control a stepper motor ...
Hello,I have an interesting situation. When I start my app on the F303RE Nucleo I initialize all the peripherals. When CAN is initialized it returns a HAL_TIMEOUT error. If I call the same initialization code a second time it initialized correctly...
I have an application using STM32H743 we wish to use the LPUART using the interrupt. We have a bootloader that is located 0x08000000 until 0x08020200. According to system_stm32h7xx.c we should move the vector table in steps of 0x200 this works for al...
Hi Team,Need the RTC Code base with LSE as clock source in wake-up counter mode and needs to get the interrupt at every 1sec rate.We have some queries regarding the LSI Clock source which is in example project.If we use the LSI as Clock, calibration ...
Hello! I have a need to use ADC1, ADC2, ADC3 and ADC4 all at the same time, and preferably DMA on all of them too. I have not coded this yet, but I am mostly wondering if there are any pitfalls or things i should think about when doing this, so they ...
Hello,I cannot find more info about this register on RM or PM documents for STM32H750XB.I'm searching for register name. The register is about enabling debug features.Am I missing something or is this register described somewhere else (maybe for all ...
Hello,I am using STM32L073VZI6 in a custom board, trying to read ADC values from a potentiometer connected to PA6. The microcontroller and the potentiometer are powered with 3.3 V.The issue is that I get 4095 when the voltage input is less than 2 V. ...
