The processor never wakes up from STOP1 mode and I do not know why. I know RTC clock is running#define RTC_ASYNCH_PREDIV 0x7F #define RTC_SYNCH_PREDIV 0xF9 /* 32Khz/128 - 1 */ void Sleep_Init(void) { HW_RTC_Init(); __HAL_RCC_PWR_CLK_ENABLE(...
I have tried using example code to read the mac ID which uses I2C connection.I have used HAL_I2C_TRANSMIT receive in my code.I am getting values but not correct values.I ahve attached the sample code along with this.Kindly help me in reading the MACI...
I have to design a special USB <-> RS485 converter using an STM32F401.I realized the project at first with a STM32F4071G eval board with DMA supported USART functions and without RTOS using STM32Cube with FW-F4_V1.25.1 and all worked fine.After porti...
1. ) STM32F072C8T6 MCU based board. Initailly it was working fine & we were able to Program using Nucleo F302R8 as ST link & Debug in IDE. Later on during development MCU was not detectable. replaced it by a new MCU but problem persisted. 2.) We che...
I am using WinBond W25Q64JV SPI Flash chip for storing data and micro controller is STM32F101RCT6. When i am try to store the data in Winbond chip it is working fine i can able to read and write data in winbond chip but if i want to overwrite the new...
Hi everyone.I am sending string data from PC and I want it get with UART of STM32F1xx but as you know I can only have 1 character.For example I am sending "234" as a string from PC, but I can see only ascii character of only 2 (ascii code of 2 is 50)...
We found a weird behavior on the STM32F334 device:The requirement is to have 2 HRTIMER's which are locked in phase to generate output PWM's.Currently we use HRTIMER1A and HRTIMER1B for the PWM's. The master timer is used to generate reset on MST per...
Can anyone help me were can i find the modbus libraries and how to implement in my code.Thank you
