I'm using ADC1 to measure the Temperature Sensor channel and the Vrefint channel. I expect those to vary very slowly and I am in not in a hurry so I am maximizing the sampling time. These are my settings in STM32CubeIDE:It generates the following in ...

I'm looking at https://www.st.com/resource/en/application_note/an4187-using-the-crc-peripheral-on-stm32-microcontrollers-stmicroelectronics.pdf. It says:Two examples are described, with the measurement of execution time:• CRC_usage example: how to co...

I'm running a STM32L496ZGT6U on a NUCLEO-L496ZG. Previously, I used the NUCLEO's integrated ST-LINK/V2-1 debugger/programmer. Now, I have sawed off the ST-LINK part of the PCB. I want to program and debug using a STLINK-V3MINI. I wired up STDC14 for...

In UM2179 Rev 9 it says:"5.4.4 Using ST-LINK/V2-1 to program and debug an external STM32 application...Note:JP4 NRST (target STM32 RESET) must be open when CN3 pin 5 is used in an external application."This is CN3: I think that should be CN5.

My system has a user-removeable SD Card. If there is a problem with the card at initialization time, the system gets stuck looping in SD_FindSCR() at stm32l4xx_hal_sd.c:3,970 0x8039632 SD_WideBus_Enable() at stm32l4xx_hal_sd.c:3,822 0x803947a HAL_S...

I see it now. Even though I selected Enable Regular Conversions: Enable in STM32CubeIDE:that, apparently, doesn't do anything. It's up to the user to manually setBit 0 ROVSE: Regular Oversampling EnableThis bit is set and cleared by software to enabl...

Interestingly, if I change the oversampling ratio to 16x, the time to EOS remains about the same.Now that I have changed the OVSR to 16x, ADC_CFGR2 is// 3 2 1 // 10987654321098765432109876543210 0b10001100 //...
