Hi,I would like to change at runtime some user-defined variables stored in Flash (so they remain on the system after power off). I have defined them as const and some are just 16 bits vars and others are more complex large structures. What is the bes...
Hello, I have a signal that is coming to a GPIO and the period of the signal might slightly change and I need to realign a timer each time the GPIO is on rising edge.I try to use the TIMER1 with Slave mode reset and use ETR1 as trigger source. but it...
I have a custom board that I am getting ready to program that is using the STM32U575. I am a little confused about the clock configuration. My board has an external 32768 crystal. I am not sure I have the MX program clock configuration correct. I wan...
Hi,I've tried finding a document that would describe what do the different error codes mean for the CAN FD module.Does anyone have a link or an idea where to search from?My CAN FD peripheral ends up in error status 516 at some point and I can't find ...
Hello. I have a question while looking at the datasheet.In the ai17535b, ai14125d image, 1uF and 10nF capacitors are indicated between VDDA and VDDS,but other datasheets (ex: MSv34738V1, MSv39402V2) indicate the capacitor capacitance as 1uF and 100nF...
Hii everyone,I am working on an inverter application . trying to implement unipolar pwm in the center-aligned mode 2. I am using DMA for the buffer transmission for the sine-wave PWM. Everything seems well without the pwm synchronization. i am initia...
I'm using stm32H750B-DK and i'm trying to send a frame via LIN protocole every one second .but when i run the code nothing happen .when debugging i found that the code blocked in an endless loop in SCB_EnableDCache() function
Hello STM Community,today while generating PWM using Alternate Function Register, I observed that for TIMER 5, Channel 1, I need not configure MOE bit in BDTR register. whereas for TIMER1, Channel 1 I had to configure the MOE bit in BDTR register. Wh...
I’m using an STM32 microcontroller and am trying to understand more about the flash memory endurance cycles. The datasheet mentions an endurance of 1 kcycle (1,000 program/erase cycles). I think possible Write and read (1000 cycles ) or is there any...
Hello!I have a major and pretty dumb problem regarding my communication between a RX2004A LCD (Documentation if needed) and a custom board with a STM32U535RET6 chipset. I'm just trying to print any message on the display. The problem is that the disp...
