In a recent design I needed an additional pin and I configured the PA13 / SWDIO pin as a GPIO input.All going fine, code works, but then this happened: After I program the chip in automatic mode and set the option byte rdp to 0xBB I can't connect aga...
Hi, We are planning to use PSRAM chip apmemory (APS12808L-3OBM) with STM32U575QII6. Please check pin assignment from STM32 to PSRAM chip And also please share the schematic and layout guidelines for STM32U575QII6 OCTASPI to PSRAM chip integration. ...
I'm using an STM32H725 to communicate with an i2c sensor. I'm using the I2C4 bus with the HAL DMA functions. I also enabled the BDMA channels for the rx and tx and respective interrupts. The problem is that the complete rx/tx callbacks are not trigge...
i use STM32N6570-DK to do a simple project but i cannot get any useful info via printf() on SWVITM data console. (1) I add some code in systemcall.c for printf() on SWVITM data console or UART1 via a "define" in my main.c. (AS many professionals sugg...
Now I want to know whether the STM32C011J6Px has a Low-Power Timer (LPTIM).Currently, we are planning to use the STM32C011F6P6 MCU in STOP Mode 2. Since we do not have any external pin interrupt available as a wakeup source, we are planning to use th...
Hi, I am using STM32H743ZI Nucleo 144 board for one of my application. As per the observations I got the utilization factor with STM32H743 is 35% where as with STM32H752 it was 60%. We have not initialized any crypto or secure features on STM32H753 b...
Hi fellows,I have a custom board with STM32F407VGT6. The board was able to be programmed via the JTAG (4 wire JTAG interface; Boot pin is pulled low to ground and reset is connected to the JTAG interface (Nrset pin)) with a segger programmer - multip...
Hi,In STM32H742xI/G datasheet (DS12110 Rev 8), the SRAM3 memory block is not specified in the "Table 7. Flash memory and SRAM memory mapping" but I can see the availability of the SRAM3 in the generated .map file.Can someone please confirm, it is typ...
Hi We are using an STM32U073CCT6 on a battery-powered board. We need to put the processor in low-power mode to increase battery life. The current in STOP MODE 2 is about 20uA. To address some issue related to the power supply and our hardware, we put...
Hello Team, One more query is there. We are not using USB. In STM32H7S7L8H6 pin D9-VDD50USB is there. So, can we connect it with 3.3V supply? Thanks & Regards, Jignesh Karena
