The "MX_RTC_Init" function called by default from the main.c resets the RTC's date and time to zero values (by default) or to some other predefined constant values.The standard practice is to set a bit in one of the backup registers after setting the...

I'm using STM32CubeMX 5.2.0 to generate a project for an STM32L0x1 device.In the code generator settings everything is selected as LL (no HAL).Nevertheless, Cube generates the selected PVD (SYS -> Power Voltage Detector In) configuration (and the int...

I couldn't find any discussions here about this newly released tool, so I'm creating one.Here is the link - STM32CubeIDE

From RM0377:6.3.3 - Peripheral clock gating......Disabling the peripherals clocks in Sleep mode can be performed automatically by resetting the corresponding bit in RCC_AHBLPENR and RCC_APBxLPENR registers (x can 1 or 2).I can't find the definitions ...

Sometimes I'm getting a I2C_EV interrupt called and none of the possible flags which can cause an interrupt are set. Only flags that are set are BUSY and TXE (ISR is 0x00008001), both of which shouldn't cause an interrupt.void I2C1_EV_IRQHandler(void...

PDF is a beast of a format (fonts, multimedia, compression, encryption, etc..), I don't think there will be a lightweight enough library without heavy external dependencies to generate PDFs in a microcontroller.Maybe you can try libharu, no warrantie...

STM32F401RB / STM32F401RC are less expensive, but they have 3 USARTs, you can use it and software-emulate the remaining one. Or software-emulate in your STM32F1.AN4655

Cube has a MCU selection tool where you can search and filter the available MCUs. Judging by your original MCU you want a LQFP64 part. You can use STM32F412RE or STM32F446RE for example.

Uh, you are right, I haven't used stm32 hardware crypto directly (only through X-CUBE-CRYPTOLIB), and it seems it prefers to work with 32-bit values. Yeah, that's logical, at the low level the values must be copied to/from hardware registers which ar...

Those functions are for unicode support, you must add the option/unicode.c file. Are you sure though that you need unicode? Maybe change _LFN_UNICODE and _STRF_ENCODE back to zero?
