Hi there, during the development I have accidently flashed (via ST-LINKv2 SWD) two chips (stm32g031j6) with program which sets PA13 as INPUT, PC14 PWM OUTPUT and initiated hardware SPI (pins PA12, PA11, PA1). After flashing this program, chip does no...
Hi, I am using STM32F779NI and Keil IDE. I have defined SRAM start area in Target options from0x20000000 with size as 0x80000. Now, I want to write a keyword at known location in the memory. The memory area should be selected such that incremental de...
Hello all I have a problem with unstable ADC readings with my STM32F030I use CubeMX to set up my device.My ADC init :static void MX_ADC_Init(void) { /* USER CODE BEGIN ADC_Init 0 */ /* USER CODE END ADC_Init 0 */ ADC_ChannelConfTypeDef sC...
In this post: https://community.st.com/s/question/0D50X00009XkYXZSA3/adc-with-dma-triggered-by-adc-watchdog-signal-peak-recordingJohn Graven posted his Code which I took and changed it a bit for my purpose. Unfortunately my Buffer adc_buf and my vari...
This is with reference to get your input regarding ADC channel reading in STM32L0 Evaluation board.I am using 4 ADC channels being configured under DMA for one of our flagship program which is running very critical by considering high business volume...
Hello,We are switching from RS232 to RS485 and are encountering problems. Everything worked properly with RS232After initializing the USART (we are using Cube), transmitting is working fine.Reception is handled by interrupt. After calling HAL_UART_Re...
I have a board in which one STM32 (call it "central") is required to update the firmware on a number of others ("sensing"). It seems simplest to use the USART1 interface for the built-in bootloader on the sensing processors. I would like to multiplex...
I am trying to change the system clock on my STM32F412 discovery board to 100 MHz using the HSI, however it just seems to crash. I am using direct writes to registers, but I looked at pregenerated CubeMX code and my registers look the same for the cl...
HiI am developing a product using stm32f429.case 1>- use cmsis_rtos2- Interrupt is generated every 20ms using exti1(PA1).- In exti1 callback function, execute gpio is set > delay 1ms > reset.case 2 >- case1 + fmc initialize codecase 1 works fine. H...
This issue i used get always even at R&D or bulk production too. It's keep on coming. Please any one help me out the exact reason. Thanks in advance.
