The software drives the SPI to drive the RF chip, and I add a 0r resistor to the SPI as shown in Figure 1, I can see through the logic analyzer that the SPI corresponds to the program one by one, but I don't understand that the RF chip does not emit ...
Hello Guys, I'm working in stm32h743 series in ethernet and i use latest version stm32 cube mx and toolchain is stm32 cube ide latest version , many times i tried but now i'm tired . Can anyone please help me with this communication protocol? If anyo...
I would like to implement a bootloader on STM32 MCU.We also plan to add a download function through CAN communication on the bootloader.How do I get CAN bootloader sample code?
Hello everyone, I have a stm32l072 microcontroller and an NB exs82 module connected via LPUART. And I'm trying to read a new .HEX firmware that is stored in the NB module's FFS and then make the microcontroller receive the packages that contain the r...
I use alternatives CAN pins PA11&PA12, based on spec standard CAN pins to use CAN bootloader are PB8-9. Is it possible to use PA11-12 to enter CAN bootloader or NOT? so far it does not work.
I am using multiple channel and multiple ADC's and I am trying to use the Interrupt method ,My first doubt was lets say we are using End Of Sequence Conversion flag So, the interrupt will be triggered when all conversion will be complete then how we ...
Hello everyone,I read PWM input value by Timer 16 bits in Nucleo-F767ZI (combined channel mode), but the value that I received is not the same after some days.For example, Day 1: PWM input value = 4200 but Day 4: PWM input value = 4000, no code chang...
Hi Team, I need to build USB PD program on ST32L562, The voltage they are expecting is up to 45V. How to do this?RegardsNithin
I used STM32F407VGT6, software-driven SPI, and analyzed with a logic analyzer, and the unpacking corresponded to the program, but there is no signal for this module, that is, it has a problem
Hello,I usually make a code based on the timer callback function to handle multiple tasks.However, I don't know why functions like printf in the systick callback function don't work at all if the flag switching is in the same function.It works If I p...
