Hello!I have a number of issues with stm32g491cet6.When using the ADC interrupt, it remains in an infinite loop. When using the HAL_Delay () function, an infinite loop also results.The code is simple and runs on the application board with stm32f103 b...
Hello, I need help to implement a function for some buttons, that every time a button is pressed a CAN message will be sent and when the button is released the CAN message will be sent again. It has to send a CAN message for falling and rising edge (...
The problem is as follows: When I am trying to update HRTIM master timer registers (MPER, MCMP1-4) on the STM32G474 via Burst DMA access, every data word I write into the BDMADR register gets written into two of the specified master timer registers. ...
I had no issue writing to and erasing the banks on my nucleo a couple times but all of a sudden it started failing. I unlock the flash successfully clear flash error flags and try do a bank erase: FLASH_EraseInitTypeDef erase; erase.TypeErase = FLA...
I'm doing project that includes outputting an increasing/decreasing duty signal for led while also working on SPI communication, from my understanding I need to set up both timer output and spi in non-blocking mode and I can do both with HAL-s interr...
HAL_SYSCFG_EnableVREFBUF(); HAL_SYSCFG_VREFBUF_HighImpedanceConfig(SYSCFG_VREFBUF_HIGH_IMPEDANCE_DISABLE); HAL_SYSCFG_VREFBUF_VoltageScalingConfig( SYSCFG_VREFBUF_VOLTAGE_SCALE1);
Hello Everyone!Couple days ago, I tried to interface STM32F030R8T6 dev. board with TFT display like on the picture with ILI9486 driver.One year ago, I interfaced the same TFT with FPGA de board and everything was fine.With STM32 I tried to interface ...
Hi,I have an STM32L073 communicating with an IS31FL3246 LED driver over I2C. Occasionally the MCU will not send the 9th clock pulse and therefore locks the bus. (As shown in the picture the analog signal has a valid waveform without much noise)Before...
Hi, I hope this is the right place to ask this.I am trying to read data from a ADS7142 in manual mode dual channel-single ended.Communication with the chip works just fine, but when the time comes to read the data, it only returns zeroesSetup:HAL_Sta...
Hello,I am working on the SM32H735G-DK Board and I would like to automate the storage in the HyperRAM for some variables by using the OCTOSPI interface. I have followed the AN5050 Application note about the OCTOSPI Interface to configure the OCTOSPI ...
