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...
My target is a 144 pin version of the STM32H5.I would like to implement both a JTAG and a FMC interface.More specifically, a 24-bit muxed-PSRAM.And I would like to output the Byte enable signals.However on this package size, there is only one possibl...
Hi,I am currently working on the firmware of a PCB with an STM32G031K8T6 as the MCU, supplied by a 1.8V voltage.When I enter Stop 1 mode, the consumption of the MCU drops to 100uA, instead of the 7uA stated in the datasheet.The app_stop function is a...
Hello,I'm new to this STM32 products. We designed custom module with STM32F103CBT6TR. We are facing issue with serial boot loader.I'm using CH340 UART to USB converter module. CH340 MOD TX --> Our Module's RXCH340 MOD RX --> Our Module's TXCH340 MOD ...
From the ES0335 errata there are two errata that look pretty significant for dual bank boot (which I'm planning to use as the basis of field firmware update):2.2.8 Dual-bank boot not working when the boot in flash memory is selected by BOOT0 pinDesc...
I have an I2C device that only operates with 1.8V logic (Pins are not 3.3V tolerant) that I want to connect to the STM32N6. I don't want to add an I2C redriver if I can avoid it. I want to keep as many of my I/O pins on the STM32N6 powered from 3.3...
I am trying to use SWD for printing using ITM_Sendchar, Printf not calling _write, I tried to put breakpoint and see, But it is not hitting breakpoint
I am encountering an issue with ADC readings on a custom board based on the STM32H533CET6.Hardware Setup: I have a simple analog filter connected to the ADC input. I have verified the input signal with a multimeter, and it correctly varies from 0V to...
Hello, I’m trying to transmit data at 2.5 Mbps (2500000 baud), but I’m not receiving any output. The same code works correctly at 2 Mbps, so the issue only appears when using 2.5 Mbps.I tested both 64 MHz and 40 MHz clock configurations for the UART....
Both in the manual and in CubeMX, it is shown that my microcontroller, has the ability to configure the FMC, for an asynchronous muxed PSRAM interface.However, in the manual I can only find the timing description for the asynchronous NOR Flash and fo...
