RTC in Vbat Mode

2024-11-25
Custom board with STM32H563 and 32.768KHz LSE and supercap for RTC in Vbat mode. I want RTC longevity in terms of weeks; it lasts 4 days. Is there anything SW can do to extend this time? For short intervals (minutes) the RTC updates fine. Disabling S...

STM32CubeIDE Project For Static Library

2024-09-11
I had a STM32CubeIDE v1.15.1 static library project against which I was linking with no problems. The static library project created the lib*.a file fine.After moving the project to a different workspace, the lib*.a file is no longer created. Instead...

ADC Conversion Time STM32H563

2024-07-09
ADC1 clocked @ 65 MHz, pre-scaler of 8, 7 channels active, 640.5 cycles/conversion, 256 oversampling, interrupts, scan mode. The numbers suggest all channels will be converted 1x in (8/65000000) * 640.5 * 7 * 256 = 141 ms. But when I look at uwTick b...

ADC Initialization Function Generated From IOC

2024-06-24
STM32CubeIDE 1.15.1, Windows, STM32H563 MCU When MX_ADC2_Init() generated by saving IOC file I get the wrong sampling time and rank for Vddcore. The IOC file shows 640.5 cycles and rank 3 but MX_ADC2_Init() shows 2.5 cycles and rank 1:   /** * @bri...

STM32F042F6P7 (TSSPOP20 package): CAN availability on CubeMx

2024-03-08
Using STM32CubeIDE (v1.14.0) with STM32F042F6P7 (TSSOP 20) to configure CAN pins on custom board. However the CAN peripheral is grayed-out when I open the IOC file in STM32CubeIDE. For pin assignments, PB8 is available for CAN rx but CAN tx is not sh...
