I am using the NUCLEO-L433RC-P development board and in the process of designing my own PCB.But I am unsure what to do with the VDD12 pinsOn the NUCLEO-L433RC-P development board they are connected to an SMPS using an analogue switch.If I dont use an...
1. According to datasheet, STM32U0 family have an IRTIM (Infrared interface). But this section is missing in RM0503. Also in SYSCFG_CFGR1 there is missing IR_MOD and IR_POL bits.2. In RTC section Figure 297 it is missing RTC_OUT2 and RTC_REFIN pins. ...
Hello,We've been working with the B-G474E-DPOW1 kit with the intention of building a custom project board using the G474E. I've had success starting with the example buck/boost project in the STM32CubeIDE (1.18.1). Now though I need to move the HRTIM...
I am trying to do OTA programming modifications using the DUAL bank feature of my STM32U575 IC with 1Mbyte of memory.I have successfully done this when the program starts in BANK 1 and I reflash BANK 2. I change the User Option byte to OB_SWAP_BANK_E...
Hello,STM32F411CE microcontroller.What is FCLK Cortex clock for the STM32F411CE microcontroller (see Figure 1 below from the STM32CubeMX (Clock Configuration tab))? Is this clock related to processor clocking? As far as I know, the processor is clock...
Good Morning, I want to use a GPIO input or a ADC input as a logical reader which gives 0 or 1 if it reads 0 or 12 Volts. However, I know the maximal rating is normally 3.6 volts for those pins. However, i saw that the Adc can still read 5 volts, it ...
Hi, I am using STM32L476RG-Nucleo64 boards for one of my ultrasound projects. Basically, the process is:1)Send 2MHz pulses with pwm2) Sample 1000points with 8-bit interleaved ADC(500 each) and DMA3) Send ADC data through SPI.4) Wait TIM3 to trigger a...
I have an application in which I'm required to check the status of an accelerometer 5000 times per second but it's a battery powered device so I want to minimize power consumption. I'm using an STM32L053C8 on a custom board with an external LSE cryst...
Hello,A design I am working on utilizes a LSE crystal with the following parameters:f = 32.768kHzCL = 12.5pFCo = 0.9pFESR = 50kR MaxDL = 1uW MAXI am calculating gmcrit ~ 1.52uA/V. According to table 5 in AN2867, the drive level should be set to Medi...
