Hello everyone, I am working on a design using STM32F401RE and need to interface a barcode scanner that works over a standard 5 V USB interface. The barcode scanner behaves like a typical USB device (likely HID/CDC) and expects: USB host on the other...
I am trying to capture timestamp values using STM32G474RE. Requirement I need to route: COMP1 output -> Timer input capture COMP2 output -> Timer input capture On each comparator edge, the timer should capture the current counter value and transfe...
Hello,I am currently working on a schematic featuring 3x STM32H753ZIT6 MCU , and I have a few questions regarding the JTAG implementation:(1) From what I’ve gathered from various sources, the NJTRST signal is a JTAG ENABLE, meaning that in normal op...
Hello,I am working with an STM32F407VGT on the Discovery board using bxCAN.I can communicate successfully at 125 kbps, but when I switch to 250 kbps or 500 kbps, communication completely fails:No messages are transmitted or receivedPCAN shows Bus Hea...
Hi,I took reference for calulating the timing / cycles for my MT29F1280AJAAA (I'm using STM32H745ZIT3) In Asynchronous mode - 5, which is saying ~50Mhz in the datasheet. But I'm running FMC at 131MHz clcok, what ever the calculation I have calculate...
I am generating a PWM signal using timer1 register and use it in Center aligned mode. I want to to know if i can modify the timer counter register TIMx_CNT register with some "x" value in the timer interrupt instead of resetting it to 0.
Hello,I want to know the DAC output buffer maximum safe output current before damaging the output buffer. I know that it's not possible to get the output swing mentioned in the datasheet under this condition.The datasheet maximum ratings doesn't stat...
Hi,This is my first time using an STM32N6 without internal flash, and since I am right before handing over files for artwork, I would appreciate it if you could check if the power lines and XSPI memory connections are correct.I have searched around a...
Hello ST Community, I am currently evaluating an architecture based on STM32H7 series MCUs (STM32H743 / STM32H7A3) and would appreciate guidance on external memory scalability and best practices. Target Architecture Bootloader in internal FlashMain a...
Hi, You know, there are some strict requirements about MCU used in optical module or production, which include1. Size and package2. Internal resource3. IO amount, especially ADC and DAC with >= 12bit resolution which be used to monitor signal and c...
