HiWhen I want timer count (CNT register) until 5000 for overflow , Set ARR = 5000-1; now I want timer count until 1 So I have to set value ARR = 1_1 (ARR = 0) But When Set ARR = 0 timer don't work and don't have interrupt. Why??how to set ARR Fo...
HiI make a 32 bit timer by to 16 bit timer3(master) & timer4(slave)Now I want my timer count antil 150000 (for example)How to get 150000 in two TIM3->ARR & TIM4->ARR register??Does it have a special formula?this number (150000) isn't fixed.I have a...
Hello,I have a strange behaviour that I cannot explain. It is regarding the determinism of running code. My setup is simple. I have a save routine that save some setup in two seperate pages (two copys of same data). So my saveroutine consists of one ...
Edits: see updates below for listen stateGenerated code using the latest CubeIDE . I2C_GetMode is always 00h. Under which conditions does this mode value change to "slave" and how to move it into slave mode ? mode = HAL_I2C_GetMode (&hi2c1); /...
Hello.I am trying to change an old source code where a new UART port is implemented using pins PA2 and PA3 (UART2). When I run the old code with changes made for UART2 I've got communication errors Parity, noise, frame and overrun error. The huart->E...

Following me prev. question:I am using STM32F429zi boardBut found a RAM_DISK example for 9i boardI ran with / without RTOSIn both cases :all these word fine (return woth OK :(FATFS_LinkDriver, f_mount, f_mkfs, But when I call f_open I get FR_NO_FILES...
Hello,I manage to operate all UART/USART DMA's except for LPUART.For some reason, only with LPUART, I fail to start DMA transaction.Is it because it's request are from DMA2 instead of DMA1 (all UART's are connceted to DMA1, except for LPUART, which i...
