I bought a second non-working used 3D printer with the expectation of repairing it. Turns out the MCU was destroyed - it actually had holes blown in its casing! I bought a few new MCUs of the exact same type, and replaced it. I can successfully put t...
There bug in STM HAL Lib generated by cube mx. Problem: I am using usb communication on STM32L433. I have high speed traffic both direction on the same endpoint. USB is stopped in one of the direction, and doesn't transmit/receive data any more.Why:I...
Hello,I am trying to overcome some strange issue using IAR when starting freeRTOS thread from main.I have used the following example for usb\en.stm32cubeh7\STM32Cube_FW_H7_V1.3.0\Projects\STM32H743I_EVAL\Applications\USB_Host\HID_RTOSIt detects a HID...
Posted on July 05, 2018 at 08:56 Hi all, I'm having a strange problem with a design using the STM32F072V8 MCU. MCU operates at 3.3V. We have a USB connector internal to the product, solely for programming the MCU via DFU. I have the BOOT0 pin...
I am currently attempting to use the USBD drivers for the STM32F765 in order to communicate over USB C as a virtual com port. I get to the point where my computer recognizes the device and the driver that is necessary, therefore the control transfer ...
I see that there is a function to write SDRAM ( HAL_SDRAM_Write_32b ) but no FLASH.I want to take data from ADC array[2000] and save so I do not loose when it is powered down.And of course recall / display it later.
Hi,I need to write a bootloader which will load the new program from a USB memory stick.Unfortunately I cannot use the ROM based DFU bootloader.The bootloader would need to be held in FLASH and protected against update. Easy enough.I believe that the...
Hi, I'm using latest FW STM32Cube_FW_L4_V1.13.0 and the PWR_STOP2_RTC example seems to fail waking from sleep mode. It goes to sleep after 5 s alright and power consumption drops from cca 11 mA to 4 uA but after cca 33 s, as stated in readme, nothing...
Posted on November 19, 2015 at 20:35The AN4286.pdf SPI Bootloader application note specifies two different commands for erasing flash. On page 24 it specifies 0x44 with checksum 0xBB. However, on page 25 the datasheet specifies 0x43 with a checksum ...
I may be mistaken but It appears that the HAL is not computing the correct value for the RD_RWN bit as defined line 6319 of the file stm32l4xx_hal_i2c.c:/** * @brief Handles I2Cx communication when starting transfer or during transfer (TC or TCR f...
