I'm really struggling with this problem. This is my first time trying to do anything low power, so please forgive any noob mistakes. All I'm trying to do is get the hang of a simple low power program so I can apply it to a larger one. My code is here...
I have an application where I must be able to update the code remotely through the CAN2 link and the embedded bootloader. This worked fine using the mass erase function, but now I need to erase sectors individually. The ap note AN3154 poorly describe...
Hello This is my first time using STM32 MCU on my own PCB. I know that I have to take many things into consideration. Please help me if I am missing somethingI have wired up all VDD/VSS/VDDA/VSSA/VUSB with bypass caps as close as I couldI have used e...
Hello, I am developing a circuit using STM32L4R9AI, VDD = 1.8v, VDDA&VREF+ = 3.13v, according to ST hardware design manual (I attached) for a better power filtration there should be bead between VDD and VDDA, will that create a problem given the volt...
Hi !I've been trying to update my STM32L496 firmware over BLE.Our bootloader use Ymodem to transfer files (as it's explained in the Application note). I have connected the UART of my BLE chip with the UART of the STM32). I can send the file (only fro...
Hi,I am using a NUCLEO F334 development board.I am using the ADC with the DMA. I developed that feature and tested and everything looked alright. I have been developing some more over that and I see that after startup the values are correct but after...
Hi everybody,Currently we have a weird thing with Ethernet on STM32H7.Everything work fine if disable cache globally.When enable cache, work fine. We can send/receive few hundreds MB or keep ping /t from PC few days, no error. So we believe we config...
In the follwoing code i would like to use same interrupt multiple times in order to blink the 4 leds different time. i am storing the data in unint8_t ABB, i expect that each time i press the button the value in ABB is incremented but practically n...
Updated Question:I have a custom PCB board with L052K8 and F051K8 with the same peripherals and correct hardware design for each (F051K8 has a VSSA for the ADC and different bypass cap), but only the L051K8 is able to program its firmware and reset c...
Hi all,I'm currently using STM32F051K8 for a smartwatch project I'm pursuing on a custom made PCB. For power consumption reasons, I wanted to change the MCU to STM32L051K8 which has the exact same UFQFPN-32 footprint.Now, my project works perfectly f...
