STM32 devices names end with: VGTx, VGHx, RETx, REYx.The first 2 seem to be associated with memory size and the last 2 to the package. Is there any logic to it and is there any document describing it?
Can someone confirm the correct part marking for STM32L072KBU6?
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...
