Multiple read from Peripheral to Memory using DMA
Dear Experts,Can I configure the DMA2 to do say 3 repeats read on GPIOx_IDR by a single DMA request? I do not want to have array of bytes instead I would like to write into a single variable and overriding it with the latest value.I have set the MINC...
ADC whit DMA. stm32f0
Hi every one.I want to read the value of a potentiometer connected to the pinA1, and if the read value is more than 2000, one of the LEDs, otherwise the second LED, will be on.Can anybody please help me? what is wrong with my code? I don't have too m...
STM32f4 Timer1 counting pulses
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...
Timers other than timer 1 don't have functioning PWM? (Blue pill)
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...
Resolved! STOP2 mode scrambles stack on STM32L4R9
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...
STM32F105 flash programming through CAN
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...
Bare metal STM32F767 PCB design
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...
Resolved! ADC power circuit
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...
STm32L496 IAP and BLE
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...
