Posted on November 24, 2017 at 16:15I tried to figure out the specification of the max. UART baudrate for the SM32H7 series (@ 400MHz system clock).The data sheet says 12.5 MBit.Does this apply to all UART ports or only selected ones?I need 8 MBits ...
Hello, for the last couple of days I've been trying to set up my STM32F723ZET6 project as a USB HS CDC device with internal PHY.My code gets stuck in this loop do { count++; if (count > HAL_USB_TIMEOUT) { return HAL_TIMEOUT; ...
Hi,I’m currently working with the STM32G491RE MCU and have encountered an issue related to GPIO pin PB6.In our normal user application, PB6 is configured as a push-pull output. However, we would like to understand its behavior when the device enters ...
HiI am working on a project with an STM32H743 and a 32-bit SDRAMThe FMC signals are quite randomly scattered across the package and this makes layout quite convoluted and difficult. I'd like to swap byte-lanes and individual bits within each byte, fo...
IS61WV25616MEBLL and IS64WV25616MEBLL are recent Muxed PSRAM from ISSI. I would like to use these with an LQFN100 STM32H750VBTx to avoid complicated routing with SRAM and going to a larger LQFN or BGA package.The FMC of this MCU supports Muxed PSRAM....
I wrote a code for this microcontroller to test the CAN protocol, and it worked successfully in loopback test mode—data was transmitted and received correctly without using any external CAN transceiver. Then, I switched the CAN mode from loopback to ...
Hi Experts,I'm almost a newbie at STM32F7xx even though I've been working with STM32F4 series.I wanted to handle the flash memory as IAP.I tried flash erase as same as what I do on STM32F4 but it failed.So I checked and found that thera are two kind ...
I am working on a STM32N6570-DK board, and I want to make sure that if I want to start a program on the external Nor Flash(the default mode), before using the Cubeprogrammer to download it, the boot0 and boot1 can both be set to 0, or boot0 has to be...
Hi All,I have a project that is using the STM32H562. I am having an issue using tim13 and tim14 to generate PWM outputs going to LEDs. The project uses timers tim2, tim3, tim4, tim13, and tim14 for a range of different PWM peripherals. For all of the...
Hi, I have an STM32F407-DISC1 connected to an Raspberry PI via I2S. The clock frequency is about 3MHz. The STM is receiving as slave on I2S2 and feeding data to a ring buffer. When the ring buffer is half full transmission on I2S3 is started (as slav...
