Hello all, I want to count pulses with TIMER 1, because he has the fastest counting frequency. I was able to count pulses with TIMER 2 but something in my code is missing to make it work for Timer 1: (I also checked the reference manual ...)Maybe som...
This problem just popped up for me. I'm not sure if I'm doing anything wrong, but timers other than timer 1 don't have functioning PWM. I configured the timers the exact same (aside from ignoring timer 1's special features,) making sure to include HA...
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...
