Has anyone ever successfully connected the CODEC TLV320AIC14 to the SAI port of the STM32F427 ?

Why I can not call function from address 0x00000000 or 0x08000000?

I have created a pointer to function like void (*MyFun)(void); and I assigned first time 0x00000000 and the second time 0x08000000. in both cases after call MyFun(); I get HardFault error.Why? PS. This is simple project created in CubeIDE (default pr...

Hello everyone,​we have to uart bootloader for stm32 mcu application. We update binary files with uart bootloader. But we need stm32 header for binary files. ​There are multiple binary files and Multiple devices that I have loaded with uart from the ...

INVSTATE hard fault with SPI interrupt handler. STM32F405

I'm attempting to have my program run some code when a SPI transfer is complete using the RXNE flag. Setting the RXNEIE bit invokes SPI2_IRQHandler() as expected but it always results in a hard fault (CFSR register = 0x20000), without any additions t...

Source Code for STM32G071R External Loader

There is an external loader for the G0 series MCUs that comes with the M01 display kit. Does anyone know where the source code to that external loader is located at?

MCO capability

I'm working on a board redesign due to supply chain issue with a NXP MK70 MCU. The previous design clocked both the MK70 and a Spartan 6 FPGA with an external 50MHz crystal oscillator.The new design is using the STM32L4R9AII6 MCU -- max HSE input fre...

I want to measure the number of impulse for signal so I use a timer en mode ETR (signal like a horloge en extern de timer) But I don't know how Create this task

SPI data transfer is not working when using registers to initialize the SPI unit

I used this function to initialize and setup STM32H743IIT6 uC to work with SPI in master mode:void InitSPI(void) { RCC->APB2ENR=0x00102000; //Enabling SPI45 clock (default: rcc_pclk2=25MHz) SPI4->CFG1=0x30070007; //Baud rate = SPI clock / 16 = 1....
