Hi there,I want the calendar/clock to retain its value after a watchdog or other non-power-on reset.Here is my code, near the beginning of main.c: // and same for the real time clock, but don't intialise it unless it's a power-on reset if (LL_RCC_Is...
HI,I'm trying to create a Flash loader for ST-Link Utility or Cube-Programmer for STM32H750.I have successfully made the STM32F7 flash loaders, while with the STM32H7 I have the following problem:17:36:19 : Connected via SWD.17:36:19 : SWD Frequency ...
Im new, hope this isnt dumb question. I have an erased STM32F303 and want to upload my code via UART1. I I have an FTDI USB to serial converter. I set BOOT0 pin=H and have the "Demonstrator" program for Windows working. Since the MCU is blank, how d...
I have multiple prototypes using the STM32F756NGH6. Some (4/10) have an odd STM32 flash failure where I can erase flash and I can write flash, but only the first 128 bits of every 256 bits. The "upper" 128 bits of flash are all 1s and cannot be writt...
Dear friends,I am using STM32F107RCt6 MCU and I am running a TCP server on it using LwIP and freeRTOS.The total heap size of freeRTOS is 10KB and there are two tasks which each task has 256 wods stack. One task is used for Modbus TCP server and the o...
I'm trying to rotate the BLDC using PWM(50% duty cyle, 2ms pwm time period). My timer initialization code:static void MX_TIM2_Init(void) { /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM2_Init 0 */ TIM_MasterConfigTypeDef sMasterCo...
error description:I wrote a function to change the UART parameter! After using this function, the UART parameter worked as installed but when the data was sent, the UART interrupt function changed a global variable of I am back to 0!Everyone can see ...
Hi!We have an application which runs on PIC24H, we would like to port it to another MCU. Application is extremely time critical, meaning that we need extremely deterministic code behaviour. In short, there are pulses which are obtained via special ha...
We have used PE6 GPIO for STM32 standby entry and PE6 is configured as initially as EXTI input mode in pull-down configuration. When there is high to low transition on PE6 STM32 jumps to standby mode. We are also using the same GPIO for coming out fo...
First time using a STM32F4 for I2S.I don't use your libraries as I want to understand the cpu at the register level.I set up the I2S PLL and enable the I2S clock.When I start to write to the SPI4 registers, they are not accepting the data. I have fo...
