I made a prototype board using STM32H7A3LIH6Q.Before the firmware was written, a current of 500mA flowed(@+3.3V).VDD and VSS were not shorted.Q1)Have there been such cases in the past?Q2)Are there any mistakes in the wiring of the circuit?Q3)VFBSMPS...
I have my own F411 PCB board, on which there are a few devices that MCU/F411 uses I2C1 (I2C HAL) to communicate.Sometimes I2C HAL API (HAL_I2C_Mem_Read, HAL_I2C_Master_Transmit, HAL_I2C_Master_Receive) calls may return with error: most of the time er...
Which is correct:BSP files assign PA6 as the LCD_RST lineSchematic assigns PA6 as the LCD_BL control lineBSP files assign PF10 as the LCD_BL lineSchematic assigns PF10 as the LCD_RST lineWhich is correct?
Can anyone please let me know, how is this possible?
Hi,I loaded the example Fx_NAND_Write_Read in a STM32H743I-EVAL and the example didn't work. So I noted that my STM32H743I-EVAL (MB1246 rev. B) has a NOR flash (MT28EW128ABA1LPC-0SIT) instead of the MT29F2G16ABAEAWP NAND flash from the example. Where...
Hello,I just ordered a STM32769I-EVAL board, it has revision B.Reading via ST-Link says: Version: 0221Build: Aug 23 2019 16:24:56I did some tests and finally wanted to reinstall the original demo software.So I downloaded the demo binary from ST webs...
I want to make USB which is operating in Device mode to enable pullup and pulldown resistors and reset without built-in VBus sensing pin. I've tried HAL_PCD_DevConnect(&hpcd_USB_OTG_FS) but it didn't work.How can I command USB to start working ?
