Hi,I m using the smooth calibrationtim1 is using an external clock 1Hz from signal generator and channel 1 is working in output compare mode generating interrupt every 32 seconds, tim2 is using LSE and channel 1 is in input capture mode.When the inte...

Hi I fixed this issue it was a problem with the -flto flag, link time optimization. The size of the output file changes if you change the orders of the source files.By disabling the -lto flag It was working no mater the order of the source files. Ena...

Hi,Include this into your project retarget.c and retarget.h and in main.c call this function RetargetInit(&huart1), this needs to be called after MX_USART1_UART_Init(), this is if you are using uart1. You can use printf after calling RetargetInit#if...

Hi thanks for your help.I was not able to use the same timer because it is a custom board stm32wb55ceu6, So I used another board nucleo f072rb. I feed one timer with the calibrated 512 Hz and other timer with the same signal generator 1Hz, And trigge...
