Hi， I'm using STM32G431 to drive my SPI screen. Due to the high cpu load, i decided to change the IT sending mode to DMA. After putting a little changes on code, it doesn't work any more, and i have confirmed it will work again once get it back to IT...
Hi,Master:platform: STM32G070CBphenomenon:When the MCU is empty (without any program), connect an external pull-up resistor 10K to the adjustable voltage source on the PA4 pin, adjust the voltage in the range of 4~18V, and find that the maximum clamp...
Hi,Anyone know where I can find memory benchmarks on using the different type of external memories on the STM32F469/79 ?How slower is the PSRAM on FMC or dual Quad SPI compare to internal SRAM ?thanks
Hi,(Sorry, I'm not sure where best to post this)After digging into issues with SPI hardware CRC on an STM32F103, it seems like the SPI HAL functions are not clearing the CRC flag before starting a new SPI transaction. I think they should be calling _...
Hello, is there any simple example for (STM32G0B1CBT6) or similar where I can simply filter int genration for eg. only for 0x505 id in standart mode. I tested many samples and I believe that there must be some bug in IDE. This is static void MX_FD...
Hello,I have a Nucleo-F439ZI as SPI master connected to four Nucleo-F030R8 SPI slaves.Initially, the SPI communication was working perfectly fine. But after a while, the master received only zeros on MISO line even though, the slaves where sending da...
Hi, I recently designed a custom stm32F405RGT6 board. However, I was unable to use the DFU mode.From what I understand, bootloader comes with DFU enabled. However, when I used stm32cubeprogrammer, it kept mentioning "DFU not detected". This is my sch...
Hi, I am looking for the STM32H series part with more GPIOs and Timers than STM32H753ZI. Can you please suggest me some of the options in H series?Below is my requirement GPIOSPII2CUARTTimerCANInternal ADC Channel6052216217
Hi Everyone, I am using stm32u575 microcontroller. I am facing issue of stuck the application code in Hardfault handler when jump from internal UART bootloader to the Newly written application code. Lets explain you the full process. I have a applica...
Hello,I have made several tries but non of them could possible solve my problem.In an STM32F030K Series, so Single Bank Flash memory, I am trying to have Flash Operation and UART module works together under the same build.I know that Interrupts durin...
