Hi All,I notice a bug in the HAL_GPIO_TogglePin() when there are two pins with different voltage level. E.g. GPIOF, Pin9 = 1 and Pin 10 = 0. It turns out Pin9 was 1 and Pin10 =0, then Pin9 and 10 = 0 then 1 and so on. Support it should be Pin9 != Pin...
I am using the STM32F4 family. I have configured a GPIO pin as output push pull with no pullups. Speed is also set to low frequency. On some occasions, the GPIO pin seems to switch polarity on its own eg. when I set to low, it will sometimes switch i...
Hello:Problem Description: When I run STM32H7 + USB_HOST bare metal, the USB HOST peripheral of STM32H7 can work normally. When I add USB_HOST to Free RTOS, the program will get stuck in the USB enumeration process to get the device descriptor. at t...
I'm going to write a new code to replace HAL_GPIO_ReadPin(), HAL_GPIO_WritePin() and HAL_GPIO_TogglePin() using direct low level memory reads, writess, and logical operation on the STM32f4.I think about a lazy way can i use the debugging to track the...
I arrange 3 main advantage for using the HAL rountines compared with direct memory access.HAL will faster than direct access.HAL will offer more easy to remember the function names.HAL will make the code more portable.Is that three advantage is corre...
Hi Guys, I'm looking at STM32L475VET6 to use as OTG Host for USB Flash drive and usb barcode reader. Since USB hub is not supported by STM32L4 what is the best way to multiplex the D+/- pins of the MCU? I will always have the barcode reader connected...
Dear All,We have implemented the communication procedure between a STM32F7691-discovery based device and the server according to the sample code of STM32CubeExpansion_Cloud_AZURE_V1.1.0. Once the device make a connection to the server, it seems that ...
The following bug occurs in the stm32h7xx_hal_eth library:When a feature of the ehernet peripheral is enabled which causes the DMA to use RX context descriptors, for example the ieee1588 timestamping unit, this leads to an inconsistent state of the R...
I am working on STM32F412CGU.I have an application which runs correctly from 0x08000000. (consists MPU, freeRTOS etc)But need to verify that image so designed a bootloader that can jump to main application at 0x08008000 address.Now the problem is aft...
Hello,I download a file from server with netcomm_recv.l write in FreeRTOS, with several tasks.For this discussion, l have two tasks.One is general task and the other is for downloading the file from server.From the first task, there is a condition...
