STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Im using a customboard and when it's able to upload and debug, it seems to get stuck at the HAL_Delay fucntion where get_systick(); always seems to return 0. problem with this is that i cannot find a way to solve this, and my SWD, on the chip does no...

I'm trying to flash ota using the BLE_Sensor iPhone app and I see different interfaces when the app is interfaced with the custom PCB and a NucleoWB55 board. The picture with the OTA config tab is the Nucleo board. The other is the custom pcb w/ modi...
Hi , I made a STM32F405VGT6 board with SD card interface. The SD code is generated using STM32CUBEMX and FatFs middleware. The SD file write is not stable, it return error sometimes after calling f_write(). However, if I run the same code in uVis...
Hi,I would like to implement a Modbus TCP server based on the library cubeMX and LWIP with the ability of multiple client connections.With only one client, it works perfectly well. With 2 clients, they can connect simultaneously but as soon as both s...
Hi all,I manage to move/modify the code for the wm8994 in the BSP project for STM32f746 disco board into my toughGFX project. I get no compile/run errors. The BSP readme says: "Copy file 'audio_sample_tdm.bin' (available in Binary) directly in the fl...
I am working on a design using the STM32F429 176pin LQFP 2MB device. Is there a F7 pin compatible part?
Hi I'm using a STM32L433 in a battery application, and running in Stop mode. I want to keep some variables in RAM2 so their values are not lost when the processor is woken up.I managed to get it working as follows. I created a block in the linker fi...
Hey everyoneI was successfully running i2s on the stm m4 cores but trying to make the jump to h7 and running into a issue. Using the same code and the DMA triggers but no code is being loaded in the rx buffer. Not sure the tx buffer is being sent out...
Have STM32G030K6T6 system that in bootloader mode fails to respond to I2C.Am asserting BOOT0 pin 25, negating NRST pin 6, wait 500ms, asserting NRST pin 6, wait three seconds, then attempt to send MCU erase packet to I2C1 device address 0x57 but get ...
