Hello,I have custom board. I am working on STM32H7 controller. We use the external crystal of 25Mhz. But when we use that external oscillator using the HSE ,it doesn't provide the clock to controller. Why these happening. Can you please help me
Need your advice. PCB routing. I have Divided signals into 4 groups + (CLK) : 1: Address: SDRAM_BA[0-1]/SDRAM_A[0-11] 2: Command: SDNRAS/SDNCAS/SDNWE 3: Control: NE0/CKE0/NBL[0-1] 4: Data: SDRAM_D[0-7] ( sub goup1 ) & [8-15] ( sub group 2) 5: SD...
So, which DS am I supposed to download for STM32L452?JW
I am unable to find any working examples for this specific board with SMBUS/PMBUS.I am also having lot's of issues converting a SMBUS project from a different board.It would be great if anyone could assist me in either getting FW specific to the boar...
Has anyone here worked with Renode? An emulator remotely similar to QEMU, but more geared towards MCUs, esp. w.r.t. emulating peripherals.https://antmicro.com/platforms/renode/Renode does not seem to have a forum, only the github issues for their pro...
Is there an easy way to find out after the WFI() instruction if the device did really sleep? Using stop modes, the device will have switched clock to HSI/MSI. Setting the clock to the state before sleep is some effort and could be omitted, if sleep...
Hello, I've tried to use ADC for two Potentiometers only with injected group conversion but couldn't make it work. I'm using STM32F446RE. I couldn't find solution so I'm asking here. Previously I read their value correctly via polling and I know that...
Hello ST Microelectronics community,I'm using a STM32H743ZI and I'm currently working on configurating properly the different I/O I want to use.To do so I need to set the set the pull up/down, open drain,etc. And also the speed mode.I could not find ...
Dear.I work with stm32l073RZ and I have a blinking led code and that code works on bank1, but it doesn't work on bank2. The strangest thing is that I also used the sample code for a flashing led from stmcubel0 and it worked. I think it may be because...
I am currently trying on the linearity calibration and I am following the protocol (down below) but I do not understand where I am supposed to get the saved linearity correction factor bits[159:150] (step 3)? Every single ADC register is 32 bits at m...
