New possibilities for the ultra-low power segment!

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...

static_cast in C?

freqError = static_cast<int32_t>(readRegister(REG_FREQ_ERROR_MSB) & B111);C has no static_cast, so how can I convert the above code to C?(It 's C++, from Arduino)

QuadSPI hangs with BUSY after 4 GB indirect read

I'm using QuadSPI in indirect dual-flash read mode to transfer data from an external chip (not flash memory). According to reference manual, when FSIZE = 0x1F and DLR = 0xFFFFFFFF, the transfer should continue indefinitely.However, with STM32H743ZIT6...

ETR prescaler bandwidth on STM32F401RC

Hello,I tried to prescale the TIM2_ETR signal on STM32F401RC, to increase the bandwith. In theory the ETR signal max frequency is 1/4 Fclock = 21 MHz, but it can be increased thanks to the prescaler. The RM0368 manual (STM32F401 reference manual) wri...
