Resolved! Synchronise 2 independent timers in OC Toggle mode
Hello, my problem is as follows:I am working with an STM32G484QET6 uC. I have configured two timers with two output channels as Output Compare Toggle Mode. So that I get two independent quadrature signals.I now want to synchronise these two quadratur...
Instruction Timings not matching ARM Cortex-M4 Manual
I am working with an STM32F3, a ChipWhisperer and the SimpleSerial library right now and trying to follow instructions executed. While doing so, I noticed that the number of CPU cycles does not seem to match what I expected from the ARM Cortex-M4 ins...
Resolved! Error: Data mismatch found at address 0x9000000D (byte = 0xFC instead of 0x00)
Hello,I recently created a custom board using the STM32F746. I'm encountering an issue with the QSPI interface. The problem arose when I replaced the external flash from the MT25QL128ABA model to the IS25LP128F model. I have checked the data sheet an...
Question about stm32f103c8
recently i been making a device that fulfill the following requirement using stm32f103c8:1. Use the STM32F103C8T6 (Blue Pill) development board.2. Connect to an RGB LED using suitable I/O pins. An RGB LED is a combination of 3 LEDs (red, green,and bl...
Modifying single byte or word and also large struct into flash
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...
TIMER1 STM32F411 Resync
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...
Resolved! STM32U575 Clock Configuration Confusion
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...
Resolved! CAN FD Error Status
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 ...
VDDA related question
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...
