Timer Call back question ?
Dear Members,I have a callback :void Timer10_Callback() { seconds += 1; if (seconds == 30) { minute = 1; seconds = 0; rpm=count; rps=(float)rpm/30; count=0; } }and main() inside while()current_rps = rps; i...

Hello, Please suggest a Software solution where I can power on the entire LPUART1 peripheral on STM32L4 only when I want. Any data received on the UART lines before I power on the LPUART1 must in no way be accessible to the MCU Hello, I have an issu...
hello, i am using the STM32L073 for adc reading. And want to use the async clocks for the dc voltage reading. so i dont need a high speed clock.The problem is when i tested the async clocks on adc , the measurement time was sometimes(30~40%) differen...
Hello,My board includes SRAM, TFT (5.0 inch with ssd1963), NOR, NAND circuits.When TFT is not connected, SRAM passes all tests (all memory read/write).(I didn't test NOR or NAND)if TFT is connected, Sram test fails any address. (Or TFT doesn't work...
I am working on creating a reverse phase dimmer where the on/off timing for the 120/240 VAC sine wave is handled by an STM32L051C8Tx MCU. There is a separate analog circuit that generates a 3V3 pulse at every zero crossing and I take this as an input...
I have a system that uses an STM32L476 controller, where we are using EXTI0 to wake up on a falling edge interrupt.My interrupt service routine used to wake up, contains an IWDG reset, so any time the interrupt gets serviced, we just reset (that's th...
I've been trying to setup the DMA on UART Receive on both the STM32H7 and F7 nucleo boards however I can't seem to get it to work. I can get the DMA on transmit to work fine but whenever i send anything to the board, either by hard wiring UART2 TX to...
Hi there,in the new MotroControl SDK there is a new ESC listed with a STM32g431. The only document that I was able to find was UM2516. Is there some more info about availability and the usual product web site? Best regards,Ingo
