Hi,I am using an STM32F777BIT6 in USB to Serial mode.Everything works fine except for a random loss of data on the windows side.After weeks of frustration I found the cause of this problem: Windows 10 CDC driver for virtual com ports. I tried the pr...
Which is the correct way to use the L4 HAL driver to start a conversion using two ADCs (ADC1 and ADC2) configured in "regular simultaneous multi-mode with independent injected" and MDMA disabled (MDMA=0b00)?The HAL_ADCEx_MultiMode_Start_DMA() only su...
lwip udp server does not send big data correctlyhelloI have implemented a udp server on stm32h7 using raw lwip.my function is reading data from sd memory and sending to pc, so I read a block(512bytes) of data from sd memory by f_read function of fatf...
Hello everyone, I am working on a project in wich I want to use a nucleo-l476RG as a MIDI device. I saw on midi official website that the USB Audioclass was compliant with MIDI application (https://www.midi.org/midi-articles/basic-of-usb). However wh...
Supposed I am using external memory via an 16 bit address / 8 bit data bus with FSMC (STM32F714). An RTOS is running.Is access to this memory atomic (in the sense of thread safety) when I read/write 32 bit wide data? The consideration is, for instanc...
Hi all,Bootloader selection for STM32G47xxxx described in AN2606 shows the different steps followed by the bootloader.Where can I find the delays available between steps ?For example, how long the booloader waits to receive the 0x7F value on USARTx ?...
Hello, I am trying to start the bootloader on a STM32F427 to program the MCU via USB port in DFU mode. I am not new to this topic because I wrote some programs for STM32F072 where I can successfully start the bootloader and take externally control of...
I'm planning to use a cheap STM32 board (either with a F103 or F401/11) as a joystick/rotary encoder controller for arcade games. I already have a working proof of concept using the old STM32duino cores (not HAL based), but I prefer to use the HAL en...
