Hi,Greetings!I have a Bourns Rotary encoder https://www.bourns.com/docs/product-datasheets/pec11r.pdfconnected to PA11(ENCA)/TIM4_CH1 and PA12(ENCB)/TIM4_CH2.Trying to use the encoder as a input control for user input.This is what I am doing: static...
Hello Friendsi'm new in STM32 i wanna know how to Read Data Byte-by-Byte from uart Rx Circular Dma and save this data in a buffer ? and my challenge is i do not know my input data length and type of that (hex, bin, ascii ,...)theres any sample code ?...
I have a project using an STM32L412. It works fine on my bench power supply, but I made it to run on a piece of modular equipment which has a different power supply - this supply is slower starting. On this supply the board seems to work fine except ...
Hello!I have been trying to get the CAN system on this to work unsuccessfully for some time now, and in trying to debug the code have added some SWV ITM console printf's. In running the code, the HAL_CAN_Init, HAL_CAN_ConfigFilter, HAL_CAN_ActivateNo...
Hello everybody!I am wondering how it would be possible to add support for the STM32G serie to the older version 7.8 of the EWARM IDE?Please advice.Regards,Konstantin
Hello,I am trying to set up a CAN interrupt base communication system and it seems that IRQ handler is never called.Debugger goes through the CAN1_TX and then back to main function, so IRq is never called.USART output:[2020-12-08_21:19:01:191] A...
I'm trying out simple SPI comms between two STM32s. The TX is STM32F407 and the RX is STM32G070. The data that I seem to be receiving is different from what I'm sending. What am I missing here?For the RX, I've set the NSS to software. I've configured...
I need to divide a 24.576 MHz signal down to 12.288 MHz for a low power ADC so thought a timer would do this easily. But either I'm missing something or I have to put a value of 1 in the compare register and reload the counter all the time which see...
I'm trying to set up the clock tree, and D1CKRDY becomes ready, but for some reason D2CKRDY does not. Here is the code:// Clock setup RCC->CR |= RCC_CR_HSEBYP; // Set HSE as...
Hello,I currently use the STM32G4 MCU Nucleo board (NUCLEO-G474RE) - I create an array of numbers (specifically - a sine wave at a certain frequency), which I transmit via the DMA, triggered by a timer (TIM2). Currently, the array is being transmitte...
