STM32H7 HAL SPI too slow for my application
I'm using HAL SPI drivers to read some MCP23S17 expander chips. I am sending a 2 byte command and receiving a 6 byte response. The trouble is there is 6 mS of delay between the write and read. Code: // read encoder expander chips for encoder button ...

Problems with i2s
Hello, I am doing a project wich takes audio from an ESP32 via I2S, process it and then send bia i2S to an amplifier wich manage I2S signals as input.HARD:ESP32 (source of audio)ST nucleo F401Re (processing unit)Amp: MAX98357A.I manage to make work p...
STM32U5A5 Semp put/get speed test
I have callback ISR code (from UART) where I put in Semaphore put and other code with Threadx static implementation with stack (SRAM2), Semaphore get, etc. I placed two GPIO signals to measure the timing between put and get. I set the compiler to opt...
[BUG] STM32 HAL driver lock mechanism is not interrupt safe
STM32 HAL driver library is full of flawed and sub-optimal constructs. The most common one, which impacts almost all drivers, is the lock mechanism. It's a bad and limiting design and getting rid of it requires a major rewrite, but the worst fact is ...
Resolved! STM32G0B1 USB device not recognized in Windows 10
Hello,I'm using STM32G0B1-Nucleo (with no USB user connector), and I am trying to program USB device (I tried virtual COM, HID and MSC separately).I'm using the STM32CubeMx with STM32CubeG0 FW V1.5.1 to generate the configuration with PA12 and PA11 f...
I know sounds dumb, but how do you configure SysTick
I need to run SysTick every microseconds instead of every millisecond. So I called: SysTick_Config(SystemCoreClock / 1000000);except that delay never ended, because the interrupt was low priority so: HAL_InitTick(TICK_INT_PRIORITY);Except this s...
Resolved! STM32F7 lwIP, TCP, dupacks and delayed retransmit - w/ source code
Hello,I'm working with a STM32F767, on a custom pcb and a Nucleo-144, same behavior, so it's probably not hardware / board related.Source code:Bare metal, no OSSAI to ETH, via DMAETH: zero copy Tx & Rxhttp server (TCP) works perfectPTP via UDP works ...
